Nylon resin high-pressure hoses are widely used in hydraulic equipment, engineering machinery, test systems, and industrial pressure transmission applications. To select the right hose, consider the following key parameters.

1.Working Pressure and Burst Pressure

The working pressure should be lower than the hose’s rated pressure, with a reasonable safety margin. Burst pressure is usually much higher than working pressure, but it should not be used as the basis for daily operation. Always consider actual pressure fluctuations in the equipment to avoid long-term operation near the upper pressure limit.

2 Inner Diameter and Outer Diameter

The inner diameter affects flow rate and pressure drop, while the outer diameter affects installation space and bending radius. For limited installation space, a more compact hose structure may be preferred. For higher flow requirements, a larger inner diameter may be necessary.

3.Fluid Compatibility

The conveyed fluid may include hydraulic oil, water, gas, or other industrial fluids. It is important to confirm compatibility between the hose inner layer and the fluid to prevent aging, swelling, or leakage caused by material mismatch.

4.Temperature Range

Operating temperature affects hose service life and performance. Applications with high temperature, low temperature, or frequent temperature changes should use hoses with a suitable temperature rating.

5.Fitting Type

Common fittings include threaded fittings, quick-connect fittings, and custom fittings. When selecting a hose, confirm the fitting size, thread standard, sealing method, and compatibility with existing equipment.

6.Bending Radius and Installation Environment

A bending radius that is too small can accelerate fatigue damage. If the equipment has limited space, vibration, abrasion, oil exposure, or other special conditions, these should be clarified in advance so that a more suitable hose structure and outer layer material can be selected.

Common Selection Mistakes

Focusing only on price while ignoring pressure rating and fluid compatibility;

Using burst pressure instead of working pressure for selection;

Not confirming fitting standards, leading to installation mismatch;

Overlooking bending radius and installation space limitations.
