Whether its for a full rebuild or some standard maintenance, the proper engine components are needed to make sure your vehicle is running smooth.

Valve stem seals are designed to prevent the mixture of air and oil within your vehicle's combustion chamber. Over time, your vehicle's valve stem seals can wear out and your vehicle will begin to burn oil. If your vehicle is burning oil or you are rebuilding your engine, we recommend replacing your valve stem seals.

All Cometic products are made in the United States with materials manufactured on American soil.

Launched by four partners including current Founder and CEO Bob Gorman in 1989, Cometic was originally dedicated exclusively to the powersports industry. Operating from a tiny 1,500 square foot manufacturing facility, the company produced a mere 900 SKUs in its first year.

The company is now wholly owned by the Gorman family - and has grown into a global leader and innovator in the highly competitive engine supplier marketplace.
