【Product Basic Overview】

The low-pressure power steering hose assembly is a core basic accessory of the hydraulic power steering system, mainly undertaking the core functions of low-pressure conveying and pressure stabilization of ATF power steering oil in the power steering system. It solves common problems of ordinary steering hoses such as poor oil resistance, easy aging and cracking in high and low temperature environments, easy damage from repeated steering flexing, oil leakage due to loose joint connection and short service life caused by outdoor harsh climate erosion. Adopting multi-layer rubber composite vulcanization integrated molding process and standardized clamp locking joint connection technology, the hose and joint fit tightly with strong sealing and excellent tensile resistance. Produced and tested in strict accordance with multiple national and international authoritative technical standards for automotive hoses. Balancing medium conveying performance, mechanical flex fatigue resistance and all-weather weather protection performance, it adapts to complex working conditions such as vehicle driving bumps, frequent steering bending, outdoor seasonal temperature differences and sand and dust erosion. No oil leakage, delamination or cracking during long-term use, effectively ensuring sensitive vehicle steering control and stable driving safety.

【Product Structure & Core Material Description】

1. Oil-Resistant Inner Rubber Layer: Made of special synthetic rubber resistant to ATF hydraulic oil, with excellent power steering oil corrosion resistance, no oil swelling and strong anti-seepage performance. The smooth inner wall reduces oil transmission resistance, no aging or impurity precipitation during long-term ATF oil conveying, avoiding oil pipeline blockage and oil deterioration, and long-term protecting precision parts of the steering hydraulic system. 2. Skeleton Reinforcement Layer: Adopting high-strength polyester fiber braided and wound reinforcement structure, improving the overall tensile, flex and deformation resistance of the hose. It withstands frequent steering bending and driving vibration tension of vehicles, no fatigue or fracture after long-term repeated deformation, and stably maintains the pipeline structure shape. 3. Weather-Resistant Outer Rubber Layer: Adopting modified special weather-resistant rubber formula, heat resistant, cold resistant, ozone resistant and UV resistant, resisting sunlight exposure, rain and snow erosion, sand and dust wear. No hardening, pulverization or cracking after long-term outdoor use, fully protecting the internal structure. 4. Assembly Connection Process: The hose and metal joint are fixedly connected with high-quality special clamps, with high pressing fitting accuracy and uniform locking force, tensile and anti-loosening, tight sealing, no oil leakage or falling off under long-term oil pressure working conditions, easy installation and strong compatibility.
