Selecting the Right Hydraulic Hose for Your Application

Choosing the right hydraulic hose is key for safe and efficient equipment use. To pick the best anti-kink hydraulic hose, hydraulic hose assemblies, or smooth surface hydraulic hose, use the “STAMPED” method. This includes Size, Temperature, Application, Material, Pressure, Ends, and Delivery.

First, figure out the size of hose you need. This depends on your system’s inside diameter and flow needs. For high-pressure work, 1/4″ (6.4mm) and 3/8″ (9.7mm) diameters are common. Longer hoses work better with 3/8″ diameter for easier oil flow back to the reservoir.

Then, think about the temperature the hose will face. Rubber hoses work well from –40°C (–40°F) to 100°C (212°F). Thermoplastic hoses are better in cold, down to –60°C (–75°F).

  • Rubber hoses are more flexible, great for high-pressure spikes.
  • Thermoplastic hoses are less flexible in cold but work well with twin hoses for torque wrenches.

Look at the application and check against SAE, ISO, or DIN standards. Make sure the hose’s material, rubber or thermoplastic, fits your system’s fluids and conditions.

Think about the pressure needs. Hydraulic hoses usually have a 4:1 safety factor. Rubber hoses have a 2:1 factor, while thermoplastic hoses offer 4:1.

Choose end fittings that match your system’s connections. Consider portability and storage. Quick couplers at both ends make disassembly fast, prevent leaks, and save on refills.

Lastly, check the delivery of the hose. Coupling hoses together can save money and make replacement easier for long runs.

By weighing these factors, you can find the right anti-kink hydraulic hose, hydraulic hose assemblies, or smooth surface hydraulic hose for your needs. This ensures your hydraulic system operates safely and reliably.
