High Pressure Power Steering Hose – Professional FAQ

1. What material options are available for high pressure power steering hose?

Industry-standard choices include EPDM (ethylene propylene diene monomer) for cost/performance, PTFE (for chemical/temperature extremes), and stainless steel braiding for enhanced pressure and abrasion resistance. Custom alloys or polymer mixes also available for unique fluids.

2. What are standard sizes and pressure ratings?

Common inside diameters range from 5mm to 18mm, with working pressure ratings of 80–420 bar and burst ratings from 320 to 1200 bar. Always select based on OEM/ISO requirements and application-specific factors.

3. What is meant by “high pressure hose for power steering pump”?

This refers to the hose handling output from the power steering pump to the steering gear/rack—subjected to the highest system pressures. Design must ensure minimal expansion, leak risk, and excellent fatigue life even at maximum load.

4. Are installation standards critical for service life?

Yes. Proper routing, bend radius (see SAE J1273), and torque on connections are essential for rated performance. Over-torque, overbending, and using incompatible fittings are common installation failures.

5. What testing & certifications should be demanded?

Insist on ISO 4079, SAE J188/J189 compliance, with hydrostatic burst test, cyclic fatigue, salt spray (ISO 9227), and traceable lot identification. For critical sectors, require full batch documentation and third-party certificates.

6. Can you supply hoses for aggressive or exotic fluids?

Yes—using custom PTFE, fluoropolymer, or specialty elastomer inner cores paired with compatible stainless/chemical-resistant outer layers. Specify fluid type, temp, and pressure for optimal selection.

7. What customer support and warranty is offered?

KEMOHOSE provides 24/7 technical support, rapid replacement for verified material/workmanship faults, and up to 24 months or 200,000+ cycle guarantee, including engineering assistance for installation & fluid troubleshooting.
