The Cometic oil pump seal is a single-pack replacement gasket made from Viton, a material chosen for its resistance to heat and oil. It is designed to seal the oil pump to the engine case, creating a reliable, leak-free connection at one of the most important sealing points in the oil system.

Riders and builders choose this seal because a compromised oil pump seal can lead to significant problems, and proper oil pressure is essential to engine health and longevity. Replacing the seal during maintenance or rebuilds is a straightforward way to help prevent future leaks and keep the oil system sealed.

Constructed from high-grade Viton, the seal offers superior resistance to heat and oil degradation compared to standard materials. It is supplied as a 1-pack, giving you a direct replacement seal for the oil pump-to-engine case interface and dependable peace of mind for your oil system.

Almost identical to OEM. Good fit. I did miss that they are sold as each and not as a pair. Small detail and my fault but it did slow my project down a bit.
