Detailed Product Description
The Sunsong 3401298 power steering pressure line hose assembly is specifically designed to meet the hydraulic requirements of various GM vehicles, including models such as the Chevrolet Camaro, Buick LeSabre, Pontiac Firebird, Cadillac DeVille, and Oldsmobile Cutlass. This hose assembly measures 31.9 inches (810 mm) in length, providing an exact fit for the power steering system's pressure line. Both ends feature male inverted flare fittings—5/8 inch on one end and 11/16 inch on the other—ensuring a leak-resistant connection to the power steering pump and steering gear.
Constructed from CSM (chlorosulfonated polyethylene) hose material, this assembly offers resistance to heat, oil, and abrasion, which is critical for maintaining system integrity under demanding operating conditions. The absence of a bracket simplifies installation in applications where mounting hardware is not required. This part is identified by the part number 3401298 and is compatible with a range of GM vehicles from the late 1990s and early 2000s.
