Detailed Product Description

The Sunsong 3401111 power steering pressure line hose assembly is built to meet the hydraulic demands of power steering systems in Nissan and Infiniti vehicles, specifically the Armada, Pathfinder Armada, TITAN, and QX56. This hose assembly uses a 16mm banjo fitting on one end and a 14mm male o-ring fitting on the other, ensuring compatibility with factory components and preventing fluid leaks. The hose material is CSM (chlorosulfonated polyethylene), known for its durability and resistance to heat, ozone, and abrasion, which helps maintain system integrity under demanding driving conditions. With a length of 48.1 inches (1222 mm), this assembly fits precisely without the need for modification. The absence of a bracket and power steering switch port simplifies installation and reduces potential failure points.
