Product Details

The Gates Pressure Line Assembly line focuses on replacement steering hoses built to match OE-style fit and function. This 358620 assembly combines a male inverted flare connection with a swivel O-ring Type I end, along with a steel tube section finished in zinc single wall steel for corrosion resistance. The hose is specified for pressure-side steering use and is sized for the pump-to-rack/gear box position.

This part cross-references Edelmann 70426 and Four Seasons 66374 for the same application. Gates 358620 is a practical replacement choice for Ford Bronco and Ford F-150 steering repairs where the original pressure line has leaked, cracked, or lost sealing integrity.

Common Uses

• Replacing a leaking power steering pressure hose
• Restoring steering assist after pressure-line seepage
• Correcting fluid loss at hose end connections
• Addressing corrosion or wear in the steel tube section
• Repairing steering noise or hard steering caused by pressure loss

Installation Notes and Tips

Verify end styles, routing, and switch-port requirements before installation. Inspect mating fittings, sealing surfaces, and adjacent steering components for wear or contamination before connecting the new line. Properly route the hose to avoid contact with moving parts, heat sources, or sharp edges, and confirm all connections are tightened to the vehicle manufacturer’s specifications.

Quality Assurance

This Gates pressure line assembly is built to OE performance expectations and uses hose material that exceeds SAE J188 specifications. The anti-corrosion steel crimp sleeve and zinc steel tube construction support durable service in power steering applications.
