  • 2. Flexibility Rubber hoses maintain their flexibility even in colder temperatures, allowing for easy maneuvering around job sites without kinking or breaking.
  • Understanding EN 857 1SC


  • Conclusion


  • 3. Fluid Compatibility Hydraulic hoses must be compatible with the fluids they carry. Moving from a 3% to a 4% hose can also mean improved material compatibility with various hydraulic fluids. This reduction in chemical degradation leads to fewer maintenance interventions and enhances the reliability of the hydraulic system over time.


  • High-pressure hoses, specifically those rated at 1% and 4%, are essential components in various industrial applications. Understanding their construction, material properties, and pressure ratings is vital to ensuring safety and performance in their designated uses. As industries continue to evolve, the demand for reliable and durable high-pressure hoses will only grow, underscoring their importance in modern operations.


  • 4. Wide Range of Sizes Spiral wire hoses come in various diameters and lengths, making them adaptable for numerous applications. This versatility allows industries to choose the proper hose configuration for their specific needs.


  • - Construction Heavy machinery such as excavators, backhoes, and bulldozers rely on hydraulic hoses to operate effectively. These machines often require hoses that can endure the rigors of rugged environments while maintaining performance under high pressure.


  • 1. Pressure Handling A 4% hydraulic hose can often be designed to handle higher operating pressures compared to a 3% hose, which is essential for demanding applications in industries like construction, manufacturing, and oil and gas extraction. Higher pressure capability reduces the risk of hose failure, enhancing system safety.


  • 5. Cost-Effective Solution By enabling on-site hose assembly, businesses can save on transportation costs and reduce the time spent waiting for replacement parts. Additionally, technicians can perform repairs using existing materials rather than purchasing new assemblies.

  • 2. Pressure Rating Choose a crimper that can handle the maximum pressure rating of your hydraulic system to ensure durability and safety.
  • The Advantages of Stainless Braided Oil Lines


  • Since hose may change in length from +2% to -4% under the surge of high pressure, provide sufficient slack for expansion and contraction.
    Never use a bending radius less than the minimum shown in the hose specification tables. The bending radius of the hose should be far away from the hose fitting (A>1.5R)
    Hose bending radius is bigger when it is in motion.
    Choose proper fittings, avoid twisting in hose lines bent in two planes.
    Avoid twisting in hose by use clamp properly.
    Hose should not be twisted, hose is weak when installed in twisted position. Also pressure in twisted hose tends to loosen fitting connections. Design so that machine motion produces bending rather that twisting.
    Leave proper length when the hose in connected
    Choose proper fittings, avoid too small bending radius and excess force.
    Choose proper fittings, avoid excessive hose length.
    Reuse friction, avoid hose touching the object directly or far away from the object.
    Hose Active Working Pressure Working Life
    As shown , when active working pressure in 1.25 times recommended working pressure, the hose working life is only half of i under working in recommended working pressure.
    Store Conditions of the Assembly.
    1.If possible, the storing temperature range is within 0-30 ℃. During storing, temperature should not exceed 50℃
    2.The storing areas can not place equipment within can produce ozone.For example mercury vapour lamp, high voltage electric device and other equipment which can produce spark or set out electricity.
    3.Can not be placed with erosive products or exposed over gas-volatile on these products.
    4.Far away from heat source and equipment which can produce electric field or magnetic field
    5.Avoid sunshine or strong artificial light source
    6.Avoid to touch the sharp objects or the ground
    7.Guarantee against rodent attacking.
    8.Observe the rule of “First in, then first out”

  • Next, check the hose's PSI (pounds per square inch) rating, ensuring it aligns with the requirements of your tools and pressure source. Additionally, look for hoses with a protective outer layer, as this will prolong the hose's life by protecting it from abrasions.


  • The Versatility and Importance of Sandblast Rubber Hoses


  • - Chemical Compatibility The inner tube material should be compatible with the hydraulic fluid to prevent degradation.


  • What are Stainless Braided Oil Lines?


  • High-pressure hoses with 1% and 4% ratings have diverse applications across various industries


  • In summary, PTFE hoses are becoming an invaluable component in power steering systems and broader automotive applications. Their unmatched chemical resistance, temperature tolerance, flexibility, lightweight nature, and durability make them a superior choice for manufacturers and drivers alike. As the automotive industry continues to prioritize performance, safety, and efficiency, it is likely that we will see an increased adoption of PTFE hoses across various functions. Adopting this technology can lead to enhanced vehicle performance and longevity, ultimately transforming the driving experience for all.
