• Constructed from durable polyacrylate material for enhanced wear resistance
• Clockwise-spiral lip design (helix type) ensures effective sealing under pressure
• Inside diameter of 1.811 inches (46.000 mm) fits specific transmission shafts
• Outside diameter measures 2.764 inches (70.200 mm) for precise housing bore compatibility
• Thickness of 0.315 inches (8.000 mm) provides optimal sealing width

Detailed Product Description and Specifications

The National 710868 torque converter seal is part of the 710800 series, designed to meet OEM specifications for automatic transmission sealing systems. Its polyacrylate construction offers resistance to heat and transmission fluids, ensuring durability in demanding operating conditions. The seal features a clockwise-spiral lip design that enhances sealing efficiency by directing fluid away from the shaft, reducing wear and leakage. With an inside diameter of 1.811 inches (46 mm) and an outside diameter of 2.764 inches (70.2 mm), this seal fits transmission shafts and housing bores precisely, including a housing bore diameter of 2.756 inches (70 mm). The 0.315 inch (8 mm) thickness provides a robust sealing surface to maintain fluid containment within the torque converter assembly.

Compatible Vehicles and Applications

This automatic transmission torque converter seal is compatible with a range of Acura, Honda, and Saturn models, including but not limited to:

• Acura MDX, NSX, RL, TL
• Honda Accord, Accord Crosstour, Crosstour, Odyssey, Pilot, Ridgeline, RL, TL, TSX
• Saturn Vue

It is specifically designed for use in automatic transmissions requiring a 32-type seal with the dimensions listed above.
