Posted by Jason Industrial on | Comments Off on How to Protect a Hydraulic Hose
In the industrial and commercial sectors, hydraulic hose assemblies are generally exposed to rough and demanding environmental conditions that gradually cause damage and degradation. They are also subjected to constant motion and vibration that cause chafing and rubbing that leads to premature wear. While both situations ultimately result in hose failure, the time it takes to reach that point may vary based on the preventative measures employed.
In the following article, we outline some of the best methods of protecting hydraulic hoses from failure to extend their service life and save industry professionals time and money.
Guard Against Erosion
One of the leading causes of hose failure is erosion, which occurs when an external leak prompts the ingress of fluid into machinery. The protective measures against this issue are as follows:
Using the correct hose size for the system’s maximum velocity rating
Checking the hose is not too tight for the flow of the system and not too abrasive for the inner tube
Following the engineer specifications regarding installation that came with the hose at purchase
Ensure Fluid Compatibility
Another common cause of hydraulic hose failure is using incompatible process fluids, which can cause the inner tube component to swell or wash out. When selecting a hydraulic hose assembly for a system, ensure all construction materials—including for the outer coverings, inner tubes, fittings, and O-rings—are appropriate for the system’s process fluids.
Monitor Insertion Depth
During assembly operations, the hose should not be pushed beyond its insertion depth, as doing so can result in failure. Be sure to check the hose’s fitting shell, which indicates the strength of its holding. It is also a good idea to use depth blocks to gauge the hose and fitting connection to ensure the hose is fully inserted without being over-extended.
Stay Within the Bend Radius
When a hose surpasses its bend radius, the tube and its cover may rip apart. Checking the engineering specifications before installing and using the hose assembly can help prevent buckling during operations. Changing the fittings, lengths, and configurations employed can also protect the hose from exceeding the bend radius.
Avoid Contamination
Contamination can occur when cutting and inserting the hose during assembly operations. Any contaminants that enter the assembly can have significant impacts on the individual hose components (e.g., cause cracks on the inner tube) and the system as a whole (e.g., cause erosion). Before attaching the hose to the fitting, clean it properly—paying particular attention to the inner tube—to prevent debris and dust from entering in the first place. Once fully constructed, the assembly should be capped to prevent contamination during transportation and storage.
Prevent Overheating
When exposed to temperatures above their maximum rating, tubes are prone to stiffening and cracking. If the outer cover appears dried out or the hose assembly emits cracking noises, the hose assembly may be experiencing overheating. Prevention methods against this issue include using hose assemblies with higher temperature ratings and integrating thermal guards and shielding for the protection of the assembly.
Minimize External Abrasions
Nearly three-quarters of all hydraulic hose failures occur as a result of external damage to the assembly. For this reason, it is important to monitor and inspect equipment for signs of wear regularly. Excessive wear may be a result of components rubbing against each other or other unwanted movements. Protective hose accessories—such as sleeves, shielding, spring guards, and wraps—can minimize the damage experienced by the assembly.

Posted by Jason Industrial on | Comments Off on Mixing & Matching Hydraulic Hose and Couplings
As we progress through our introduction of hydraulic hose and coupling products at Jason Industrial, there have been a number of requests for interchange to competitors’ hose and couplings.
The term “interchange” needs to be clarified. No hydraulic hose or coupling is truly interchangeable because each manufacturer produces products that are tailored to their own processes and equipment. This is why mixing and matching is never recommended by anyone concerned about the satisfaction and safety of their customers and end users. Even though a particular hydraulic hose may carry the same SAE, ISO, or EN standard labeling, they are not made to the same tolerances and materials.
The same is true for couplings, perhaps even more so. Nearly every manufacturer has developed their own unique designs customized for their own validated and approved hose products. Additionally, the assembly specifications for crimping these hoses and couplings are unique to each piece of equipment.
Let’s focus on the coupling side of interchange for today’s discussion. Jason currently has three series of couplings for our hydraulic hose products.
The JB12 for our 1 or 2 steel braid reinforced hoses
The JB40 for our 100R12
The JB60 for our 100R13
Other manufacturers may have one series that covers both wire braid and some wire spiral such as 100R12 or even 100R13 (skived). Others may have a series that covers thermoplastic hoses like 100R7 and can be crimped on certain wire braid hoses like 100R16, but not 100R2. While there are many similar examples, the bottom line is always the same: it is never going to be a one to one direct interchange.
So how do you address this when you’re working with a customer who could move to Jason as a supplier? We recommend that you first sort out which hoses the customer is using or wishes to buy. Once you’ve established this list, evaluate the competitor’s couplings to identify an equivalent Jason part to provide the connector ends needed for the hoses we’re offering. This will ensure that the customer will have the correct hose and couplings for their needs when an order is processed.
Posted by Jason Industrial on | Comments Off on California Proposition 65: Compliance and the Jason Industrial Portfolio of Products
Effective August 30, 2018, Proposition 65, also known as the Safe Drinking Water and Toxic Enforcement Act of 1986, will be expanded to include almost 1,000 chemicals known to cause cancer or reproductive toxicity. As a result, the previous generic warning enacted in 1986 will need to be replaced with a warning that identifies specific chemical ingredients used in the manufacture of products shipped to California.
Full implementation of the Prop 65 amendment means that violators will face sanctions for failing to comply with the requirements set forth. Jason Industrial is making sure that we will be fully compliant with Prop 65 before the deadline. To further explain this law and its purpose, we will explore the history of Prop 65, why there is a demand for more specific warning labels on product packaging, and the steps we are taking to achieve full compliance with the law.
History of Proposition 65
When it was enacted and approved by a majority of California voters in 1986, Proposition 65 – or the Safe Drinking Water and Toxic Enforcement Act of 1986 – sought to keep harmful and carcinogenic chemicals out of California’s drinking water, and to warn residents if water they used for drinking and cooking had been potentially contaminated. The list of harmful chemicals has grown significantly since that time—there are now more than 1,000 chemicals on the list.
Previously, only generic warning labels on products containing these chemicals had been required. In 2016, the law was amended to require all businesses to add more specific warning labels on the full range of products now covered by the law.
Jason Industrial’s Compliance
Jason Industrial is currently taking all required steps to be fully compliant with Prop 65 before the deadline. As a first step, we have identified all products that need packaging with the required new labels under the amended Prop 65.
These products are shipped from our branches, whether to California or from other U.S. customer locations that may ship to California will have the proper warning label attached. Additionally, we will label the outside of shipping boxes noting Megadyne Americas compliance with Proposition 65 beginning August 30th, 2018. Customers receiving products that include chemicals noted on the revised proposition must ensure they carry the warning labels to their customers.
To ensure that we do not miss anything, we will send instructions and labels to all Jason Industrial shipping points so that products which may contain these chemicals can be pinpointed.

Posted by Jason Industrial on | Comments Off on How & When to Replace a Hydraulic Hose
In hydraulic systems, hoses carry pressurized hydraulic fluid to or from pumps, motors, valves, actuators and other system components. Due to their critical function, the hoses employed are designed and constructed for suitable flexibility and durability. They must be flexible enough to bend in and around the confines of equipment, fit into tight spaces and may span long distances while being durable enough to withstand the high operating pressures and temperatures. For these reasons, they are generally made from a combination of multiple layers of materials—such as elastomers, fluoropolymers, thermoplastics, textiles and metals. Typically, hydraulic hoses have an inner lining or tube made of rubber or thermoplastic, braided or spirally applied reinforcement layers of textile yarn or wire and a cover also made of rubber, thermoplastic or braided material. All of these are uniformly bonded together as one unit. Finally, for a hydraulic hose to be useful it requires suitable connections with hose fittings (permanent or reusable type) designed to attach to the hose to allow full utilization of the hose’s rated pressure and performance for maximum service life. It is vital to achieving this maximum acceptable service life and safe use that only manufacturers matched and approved components must used together and assembled to their recommendations. Mixing/matching of hose components outside of this recommendation can lead to unsatisfactory performance and disaster.
While hydraulic hoses are highly durable, the pressure cycles they experience through normal operation and natural degradation will eventually lead to failure. If hose failure occurs unexpectedly, it can result in employee injury, property damage, expensive cleanup, wasted production, unscheduled downtime and increased material and labor costs. With these consequences in mind, most hose experts recommend a proactive rather than reactive approach to hose replacement—i.e., replacing the hose assembly once it nears the end of its safe and useful life span but before it fails—for the sake of safety and cost savings.
Given the durability generally demonstrated by modern hydraulic hoses, it can be challenging to know when it’s time to replace them. Sometimes there are obvious signs that a hose has begun to fail, but that’s not always the case. In the following article, we discuss when and how to replace hydraulic hoses.
What Is the Typical Service Life of a Hydraulic Hose?
The Society of Automotive Engineers (SAE) has generally set the standard shelf life of unused bulk rubber hoses to six years total ( 4 years as bulk and 2 years as assembly) from their date of manufacture when properly stored. However, there are many factors that influence the actual working or service life of a hydraulic hose, such as the type and temperature of the fluids, operating pressure and flow, static or dynamic conditions and environmental conditions. While the hose manufacturer or distributor can provide insight into the expected working life when in doubt, replacement should not be delayed if the hose is showing any signs of wear or degradation. Most hydraulic hoses are designed to pass the cyclical impulse pressure requirements at specific pressure levels above the rated working pressure, temperature and bend radius. This qualification testing requires the use and assembly with the properly specified end fittings attached to the hose for a number of cycles. For example, most two wire braid hoses require a successful testing of a minimum of 200,000 pressure impulse cycles, while most wire spiral hoses require at least 500,000 cycles. This is why wire spiral hoses are normally considered longer service life hoses for equipment running lots of pressure surges within the hydraulic system.
You must keep in mind that every application is different and no manufacturer can predict with accuracy a service life for a particular situation without in depth knowledge of all parameters. The equipment designer bears this responsibility for a given system.
Generally, if the service life of a hose has proven to provide acceptable durability, replacement with the same or better rated hose should also provide similar life. The branding on the hose can usually provide the rating such as the manufacturer’s part number and/or the SAE or ISO ratings.
Factors Influencing the Service Life of Hydraulic Hoses
As indicated above, the actual working life of a hydraulic hose depends on many factors. Some of the considerations to keep in mind when assessing how long a hose assembly may provide acceptable service life include:
Size: Hydraulic hoses differ in size depending on the anticipated flowrate needs of a system. It’s important to be aware of the limitations of the hoses employed to avoid exceeding their operating capacities. Excessive velocity will damage the inner surfaces of the hose’s tube and other system components may be damaged from the tube debris. Excessive flowrate will also raise the temperature of the hydraulic fluid due to friction. Using a simple nomograph provided by the hose manufacturer provides guidance in safely sizing the hoses for hydraulic system’s pressure and return circuits once the pump output flowrate is selected. Normally, return hoses must be sized larger than pressure lines (see manufacturer’s nomograph).
Temperature: Typical rubber hoses are designed for operating temperatures ranging from -40° F to 212° F. Certain other hose materials can provide safe performance up to 250°, even 300° F. PTFE tubed hoses can safely be used up to 450° F. Hydraulic fluids or ambient conditions outside of this range can lead to premature failure. Higher temperatures can lead to the hose becoming hard, brittle and cracked, while lower temperatures result in the hose becoming cracked without losing its softness or flexibility. The cooler the hose fluids can be usefully used at well below the rated maximum, the longer the hose will be able to not experience material degradation. Care must be taken to properly route and shield hoses away from external heat sources such as engine manifolds which can quickly reduce the life of the hose and often lead to fires.
Pressure: In addition to having set operating temperatures ranges, hydraulic hose assemblies have maximum rated working pressures. If the system pressure exceeds beyond this point, the hose may suffer permanent damage and/or fail. For this reason, it is recommended to use hoses rated for a few hundred psi over the system’s maximum working pressure to avoid surpassing the hose’s rating. The integration of quick acting pressure-relief valves can also help minimize the risk of excessive pressure spikes. Pressure spikes create cumulative damage within the hose and adds up over time and eventual likelihood of hose failure.
Application: Each hose is designated for a specific set of system functions and duty cycles. However, even when used properly, hoses can be damaged by environmental factors related to their application. For example:
Hoses used in mobile equipment often rub against other equipment components or even other hoses, which leads to damage to the cover and reinforcement over time. Again, routing of hoses near engine exhaust components can quickly damage a hose from the high temperatures.
Hoses used in indoor environments may be exposed to higher temperatures, especially when situated near furnaces or ovens, which can lead to thermal damage.
Hoses used in vertical installations experience more stress than those used in horizontal installations.
Hoses used in applications with cyclical pressure loading can move due to up to 3% change in length. Hoses have to be routed and design length chosen to account for this movement. Any such application should have suitable inspection of the hose to see if there is degradation of the hose itself or the connections leaking. Any rotation of the fitting swivel under use will lead to leakage or ultimate failure unless the connection is made using a “live swivel” intended for dynamic swiveling.
If the hose is installed on components that experience movement (such as a pivoting hydraulic cylinder) routing is very important to allow for proper length for flexing and all twisting or bending in multiple planes of the hose should be avoided.
While these conditions may be unavoidable, ensuring the hose is properly installed and implementing protective measures (e.g., hose guards or shielding) can significantly extend the service life of the hose assembly.
Fluid: When selecting a hydraulic hose assembly for a system, ensure all of its construction materials are compatible with the chosen hydraulic system fluid. Its compatibility can be determined by checking the Material Safety Data Sheet (MSDS) for the fluid in combination with the hose manufacturers listings of compatibility. Using incompatible materials can damage the assembly and compromise system performance. Some fluids can easily damage the hose tube and lead to failure, so you must make sure of compatibility with the hose.
Signs Signaling a Need for Hydraulic Hose Replacement
While it is often difficult to determine whether a hose assembly needs replacement, there are some visual cues that indicate it has reached the end of its service life. For example, if the hose assembly has any of the following conditions, it must be replaced:
Crushed or distorted hoses
Fluid leakage (within the hose length or at the fitting end)
Exposed wire reinforcement
Significant surface damage (beyond scuffs and small nicks)
Kinks (an indication of incorrect routing)
Twisted hoses (another indication of incorrect routing)
Hardened or blistered cover as well as any signs of the cover softening significantly which may signal a fluid compatibility problem
Corroded fittings (white oxidation is normally, acceptable while red rust warrants replacement)
Steps for Replacing Hydraulic Hoses
The replacement process for a hydraulic hose is as follows:
Identify the issue. Verify which hose is damaged before removing and replacing it. Be thorough in assessing the situation to ensure that the repair actually addresses the problem. With this information in hand, purchase a suitable replacement that will provide same or better performance rating.
Assess the situation. Check what system components need to be removed to allow for the replacement of the problem hose.
Prepare the system. Address any components connected to and around the hose to ensure they do not hinder the replacement process. This step must include relieving pressure to avoid the leakage of process fluids, lowering pieces to the ground to prevent them from falling and removing parts to allow for an obstructed view and workspace. Note, at this point it may be useful to photograph a few suitable views of the hose’s routing to assure a replacement is put back in place properly.
Loosen the fittings. Once the hydraulic assembly is prepared for the actual replacement operation, loosen the fittings as required that attach the hose to the machine.
Remove the hose. When the fittings are loosened, remove the hose and pour any residual fluid into a waste container.
Seal the fittings. Before installing the replacement, seal the fittings with a designated fitting plug or rag to avoid further leakage.
Install the new hose. Install the replacement using the proper techniques and reassemble the rest of the system. Refer to manufacturer’s recommendations for details and any applicable torque recommendations. Consider tagging the hose (see later in this document).
Visually check the installed hose. This will help make sure the installation is proper in routing and connection.
Test the system. Once the hose assembly is replaced and the system is fully reassembled, test the system to ensure there are no leaks or performance issues.
Determine Replacement Intervals
Keep records as to what the inspection of the hoses is showing regarding hose durability and determine what replacement intervals may be needed to assure hoses are replaced before failure. Tagging the hose when installed, inspection intervals and replacement dates will help in this process. The goal is to make sure that the hoses are replaced before failure.
