Detailed Product Description

This National 224215 seal is specifically designed for manual transmission extension housings, ensuring a tight seal around the shaft to prevent oil leakage. The polyacrylate material offers resistance to heat, wear, and transmission fluids, making it suitable for demanding automotive environments. The counter-clockwise spiral lip design enhances sealing efficiency by maintaining consistent contact pressure on the shaft, reducing the risk of contamination and fluid loss.

With precise inside and outside diameters, this seal fits the housing bore and shaft dimensions commonly found in Nissan models such as the 300ZX, D21, Frontier, Pathfinder, Pickup, and Xterra. The 8 mm thickness provides a robust barrier against leaks while accommodating slight shaft misalignments.
