Sunsong 3401897 Power Steering Pressure Line Hose Assembly - Pump To Hydroboost

Power Steering Pressure Hose Assembly

Sunsong 3401897 is a power steering pressure line hose assembly built for OE-style replacement on select vehicles that use a 16 mm male O-ring end and an 18 mm male O-ring end. It is engineered for consistent steering-fluid transfer under pressure, with corrosion-resistant steel tubing and CSM hose materials for long-term service.

For drivers searching for a power steering pressure hose for Honda Civic or similar OE replacement steering hose applications, this part number 3401897 is built to restore proper hydraulic routing and pressure control. It cross-references Gates 365120 for the same application.

• Burst pressure rating of 8,700 psi
• Tensile strength rated at 1,600 lb
• High-grade steel tubing with zinc electroplating for rust and corrosion resistance
• Precision-engineered hose assembly for exact fitment
• End fittings: 16 mm male O-ring and 18 mm male O-ring
• Length: 43.3 in. (1099 mm)
• CSM and steel construction for durability

Detailed Description

Sunsong 3401897 is a replacement power steering pressure line hose assembly designed to meet demanding hydraulic steering requirements. The hose construction combines CSM and steel materials, while the tubing uses zinc-coated steel to resist moisture, road salt, grime, and other underbody exposure. This makes it a practical choice for OE replacement on vehicles such as Honda Civic applications where pressure-line integrity matters.

The assembly is built to exact fit standards and is high-pressure tested before leaving the factory. That attention to fit and pressure performance helps support stable steering response and reliable fluid delivery in everyday driving. If you are replacing a worn or leaking pressure hose, part number 3401897 provides a direct-service solution for steering systems that use male O-ring connections.

Common Problems This Part Can Address

• Power steering fluid leaks from a cracked or worn pressure hose
• Steering noise caused by pressure loss in the hydraulic line
• Hard or inconsistent steering effort from restricted fluid flow
• Corrosion damage on exposed steel hose tubing
• Failed hose fittings at the O-ring connection points

Installation Notes and Tips

Verify end fitting sizes, routing length, and connection style before installation. This hose uses male O-ring ends and measures 43.3 inches long, so matching the original routing path is important for proper clearance and alignment. Inspect mating surfaces, seals, and adjacent steering components for wear before installing the new hose.

For Honda Civic pressure hose replacement searches and other OE-style steering repairs, confirm the vehicle’s hydraulic line configuration against the original part number 3401897 and the existing hose layout.

Quality Assurance

Each Sunsong pressure hose is pressure-tested before shipment to help ensure proper operation after installation. The manufacturer states that this assembly is engineered to exceed original equipment performance standards in pressure capacity and durability.
