Detailed Product Description and Specifications
The Sunsong 3402312 power steering pressure line hose assembly features a robust CSM (chlorosulfonated polyethylene) hose material, known for its resistance to heat, oil, and abrasion. This 44-inch (1117 mm) hose is equipped with male o-ring fittings on both ends—16 mm on one end and 18 mm on the other—ensuring a secure, leak-resistant connection within the power steering system. The absence of a bracket simplifies installation in compatible Ford Super Duty trucks, while the lack of a power steering switch port indicates this hose is designed for models without integrated pressure sensors.
