Womala Power Steering Pressure Return Hose Line OE 1644602224 for Mercedes
The Power Steering Pressure Return Hose Line (OE: 1644602224) is a key transmission component of the power steering system for Mercedes Benz W164 series GL models. It connects the power steering pump and steering rack, responsible for transporting hydraulic fluid back to the reservoir. As an OE-grade part, it meets Mercedes’ strict standards for pressure resistance, leak-proof performance, and durability, ensuring reliable operation across conditions (e.g., engine vibration, temperature fluctuations, long-term use).
Constructed from high-performance materials: the inner tube uses oil-resistant rubber (to withstand power steering fluid corrosion), while the outer layer is reinforced with fiber braiding (for pressure resistance and shape retention). Precision-molded fittings ensure tight connection with system components, avoiding fluid leakage.
Core Functions
Fluid Circulation: The primary function is to guide the return flow of hydraulic fluid, completing the power steering system’s fluid circulation cycle.
Pressure Resistance: Withstands the hydraulic pressure of the return line, preventing hose burst or deformation under working conditions.
Leak-Proof Protection: Tight fittings and high-quality rubber material ensure no fluid leakage, maintaining stable hydraulic pressure in the system.
Compatible Vehicles
This Power Steering Pressure Return Hose Line is tailored for the following Mercedes models and its respective OE number:
Notes: This Power Steering Pressure Return Hose Line is model-specific and designed exclusively for the listed Mercedes W164 series GL models. Do not use it for other models or variants to avoid mismatched fittings, insufficient pressure resistance, or fluid leakage. During installation, ensure the hose is routed correctly (avoiding kinks or contact with high-temperature components) and fittings are tightened securely. Use only Mercedes-approved power steering fluid. Periodically check for hose aging, cracks, or leakage, and replace immediately if faulty to maintain the power steering system’s normal operation and driving safety.
