Common Problems This Hose Can Address

• Power steering fluid leakage from a worn or damaged pressure line
• Loss of steering assist caused by pressure loss in the hydraulic circuit
• Noise or stiffness in steering operation related to restricted fluid flow
• Corrosion-related hose or tube deterioration in harsh road conditions
• Fitment issues when replacing an aging original hose assembly

Installation Notes and Tips

Verify the end fitting types and sizes before installation: End 1 is a Male O-Ring, size 18, and End 2 is a Flange, size 11. Confirm routing, connection points, and vehicle application before removal of the original line. Because this is a pressure line hose assembly, clean the mating surfaces and inspect related steering components for wear or contamination during service.

Quality Assurance

Each hose is pressure tested before it leaves the factory to help ensure proper operation after installation. Sunsong builds this assembly with high-pressure durability targets and corrosion-resistant tubing to support long service life in steering system use.
