Internal Seal Ring

Transmission seal rings help to engage rotating clutches in transmissions and torque convertors. They allow oil to flow from a stationary component into a rotating component while minimizing fluid loss.Cat® Seal Rings are made of a various materials including rubber, energized rubber, and plastic. These seals are capable of handling the most aggressive pressure and speed applications. From the seal ring geometry to the finish and heat treatment of mating surfaces, all aspects of the sealing system are engineered to work together, resist wear and provide reliable performance.
