Sunsong 3401790 uses precision-engineered dimensions, 1\/2 in. male O-ring ends, and an 11 in. length to match the listed steering cylinder applications. The hose construction combines CSM material with steel tubing protected by zinc plating, helping resist rust, road salt, moisture, and grime in demanding underhood and chassis environments. Sunsong 3401790 is also pressure tested before it leaves the factory to support consistent operation after installation.\u003c\/p\u003e\u003cp\u003eThis part cross-references Gates 355600 for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePower steering fluid leaks at the cylinder line hose\u003c\/li\u003e\n\u003cli\u003eLoss of steering assist from a damaged hydraulic line\u003c\/li\u003e\n\u003cli\u003eCorrosion-related hose or tube deterioration\u003c\/li\u003e\n\u003cli\u003eImproper sealing at O-ring style fittings\u003c\/li\u003e\n\u003cli\u003eSteering noise or erratic assist caused by restricted fluid flow\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eConfirm the vehicle uses the listed cylinder application and O-ring fitting style before installation.
