Detailed Product Description

The National 710796 transfer shaft seal is constructed from polyacrylate, a material known for its resistance to heat, wear, and transmission fluids. Its 32-type clockwise-spiral lip design ensures a tight seal around the shaft, minimizing the risk of oil leakage in automatic transmissions. With precise inside and outside diameters of 1.890 inches and 2.646 inches respectively, this seal fits securely within the housing bore of 2.638 inches, maintaining optimal sealing pressure. The 0.295-inch thickness provides a robust barrier against contaminants and fluid loss, contributing to the longevity of the transmission system.
