Product Details
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.

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.
