Detailed Description
This Sunsong power steering pressure line hose assembly is built to meet demanding steering system requirements on Jeep TJ and Jeep Wrangler platforms. Part number 3402414 uses a 16 mm female O-ring fitting on one end and an 18 mm male O-ring fitting on the other, with a 46.6-inch overall length for the specified applications. The hose is constructed with CSM material and is designed for pressure-line use where consistent fluid transfer and secure sealing are critical.
According to the manufacturer, this hose assembly is engineered to exceed original equipment performance standards, with a maximum working pressure of 1,500 psi, a burst pressure rating of 8,700 psi, and tensile strength of 1,600 lb. Sunsong also states that its pressure hoses are high-pressure tested before leaving the factory. This part cross-references Dorman - HELP 80474 and Gates 352023 for the same application.
What This Hose Helps Address
- Steering fluid leaks from a worn pressure line
- Loss of power steering assist caused by hose damage
- Cracked, hardened, or deteriorated hose material
- Incorrect sealing at O-ring connections
- Pressure-line failure on Jeep TJ and Wrangler steering systems
Installation Notes and Tips
Verify end fitting sizes, hose routing, and PS switch port requirements before installation. Match the hose to the vehicle’s steering layout and inspect mating surfaces, O-rings, and related components for wear or contamination. Proper routing helps prevent chafing, heat exposure, and premature hose damage.
Quality Assurance
Sunsong subjects each hose to high-pressure testing before it leaves the factory to help ensure consistent operation and installation readiness. The manufacturer also specifies pressure ratings and corrosion-resistant steel tubing with zinc coating for durability in harsh road conditions.
