Detailed Product Description

This Sunsong power steering pressure line hose assembly (part number 3401276) is manufactured to meet the specifications required by Chevrolet and GMC full-size vans and trucks, including the Express and Savana series. The hose is made from chlorosulfonated polyethylene (CSM), a material known for its resistance to heat, oil, and abrasion, which helps maintain hydraulic integrity under demanding conditions. Both ends feature male o-ring fittings—16 mm on one end and 18 mm on the other—ensuring a secure, leak-free connection within the power steering system. The absence of a bracket simplifies installation in vehicles where the original hose did not include one.
