Detailed Product Description

The Sunsong 3401373 power steering pressure line hose assembly features a 43-inch length made from chlorosulfonated polyethylene (CSM), a material known for its excellent resistance to heat, ozone, and hydraulic fluids. Both ends of the hose are equipped with male o-ring fittings—16 mm on one end and 18 mm on the other—ensuring a tight, leak-free seal within the power steering system. This assembly does not include a bracket and does not have a power steering switch port, simplifying installation in compatible vehicles.

Specifically engineered for use in Chevrolet Express and GMC Savana full-size vans, this hose assembly supports the hydraulic pressure needed for smooth steering operation. The part number 3401373 corresponds directly to these models, providing a precise replacement option for maintaining factory steering performance.
