3. Manufacturing Process of High Pressure Power Steering Hose

Step-by-step Process Flow

1
Material Selection & Inspection
Only certified raw materials (EPDM/ PTFE/ Stainless Steel) are sourced and verified for tensile, abrasion and chemical resistance.
➜
2
Extrusion & Inner Tube Forming
Inner tube is extruded at controlled temperature & thickness for optimal hydraulic fluid compatibility.
➜
3
Reinforcement Braiding
High-tensile synthetic yarns or steel wires (1/2-layer) are precision braided for burst & fatigue resistance.
➜
4
CNC Machining of Fittings
End-fittings are precisely cut, grooved and threaded by CNC (Computer Numerical Control) machines.
➜
5
Assembly & Crimping
Hose and fittings are assembled and hydraulically crimped using advanced presses to guarantee leak-free connections up to 850 bar.
➜
6
Hydrostatic Testing & Inspection
100% tested for internal leakage, pressure cycle and dimensional accuracy per ISO/SAE. Select batches tested for ozone, UV and salt spray corrosion resistance.

9. Expert FAQ: High Pressure Power Steering Hose

Q1: What material options are available, and how do I choose the right one?
Main options: EPDM (excellent temperature and ozone resistance), PTFE (best for aggressive fluids, higher cost), NBR (general use), and stainless/nylon braiding. Choose based on your system’s fluid (ATF, mineral oil), operating temp, and corrosion risk.
Q2: What is the typical working pressure for a high pressure power steering hose?
Standard hoses: 120–210 bar working pressure; custom solutions up to 320 bar. Check both pump specs and steering rack limits for safe selection.
Q3: How does custom fitting/connector choice affect installation?
Correct end-fittings (JIC, DIN, ORFS, BSP) ensure leak-free, vibration-resistant joints and reduce the risk of hose twist or abrasion. Custom-tailored length and bend angle also minimize installation time.
Q4: What testing protocols ensure my hose meets global standards?
All hoses undergo hydrostatic burst, pressure cycling (ISO 6802), and dimensional/corrosion resistance testing (FMVSS 106, EN 857/853).
Q5: What guarantees does Kemo Hose offer?
12–36 month written warranty covering manufacturing quality, dimensional compliance, and burst resistance, with quick-response technical support worldwide.
Q6: What is the recommended minimum bend radius?
