Technical Details and Specifications

This manual transmission output shaft seal from National is part of the 220000 series and is constructed from nitrile, a material known for its resistance to petroleum-based fluids and mechanical wear. The seal features a 1.575 inch (40 mm) inside diameter and a 2.058 inch (52.28 mm) outside diameter, fitting precisely into a housing bore of approximately 2.047 inches (52 mm). The 0.276 inch (7 mm) thickness ensures a secure fit and effective sealing against oil leaks. The clockwise-spiral lip design enhances sealing efficiency by directing fluid back into the transmission, reducing the risk of contamination and premature wear.
