Product Description
High Pressure Power Steering Hose
A power steering hose is a critical component in vehicle hydraulic steering systems, designed to transport pressurized hydraulic fluid between the power steering pump, steering gear/rack, and reservoir. These flexible yet durable hoses withstand continuous exposure to high pressures (typically 150-1,500 PSI) and extreme temperature fluctuations (-40°F to +300°F).

Multi-layer Construction:
  • Inner tube: Synthetic rubber or thermoplastic resistant to hydraulic fluid degradation.
  • Reinforcement: Braided steel wire, textile mesh, or spiral-wound fibers for pressure containment.
  • Outer cover: Weather-resistant EPDM or CR rubber to protect against abrasion and environmental damage.
⚙️ High-Pressure Supply

Handles peak system pressures from pump to gear.

🔄 Low-Pressure Return

Directs excess fluid back to the reservoir.

🛡️ ISO Certified

Complies with SAE J188 and ISO 11425 standards.

Frequently Asked Questions
What are the primary materials used in these hoses?
The inner layers are typically made of oil-resistant synthetic rubber like NBR or HNBR, reinforced with high-strength fiber or wire braided layers, and covered with wear-resistant polyurethane or rubber.
Can you produce hoses based on custom samples?
Yes, production can be customized according to specific samples or technical drawings provided by the customer.
What testing standards are performed before delivery?
All goods undergo 100% visual inspection and rigorous performance tests, including pulse pressure tests and leak proof checks, to ensure compliance with ISO and SAE standards.
What is the typical working temperature range?
The standard operating range is -40°C to +120°C, with short-term tolerance capability up to 135°C.
What types of hydraulic fluids are compatible?
These hoses are compatible with Automatic Transmission Fluid (ATF) and Power Steering Fluid (PSF) meeting Dexron or ISO 7308 standards.
What are your standard delivery terms?
Commonly used delivery terms include FOB, CIF, EXW, and CFR, with a general lead time of approximately 45 days depending on order volume.
