Detailed Product Description and Specifications

This power steering pressure line hose assembly from Sunsong features a robust CSM (chlorosulfonated polyethylene) hose material, known for its resistance to heat, oil, and abrasion, which is critical for maintaining hydraulic integrity under demanding conditions.
