Ferrea 11/32 .500in ID Viton Hi-Temp Exhaust/Intake Valve Stem Seal - Set of 16

If you're rebuilding the top end of your engine, replacing the valve stem seals is a critical step to prevent oil from getting into the combustion chamber. These Ferrea valve stem seals are made from Viton, a material known for its excellent resistance to high temperatures and aggressive fluids, making them a solid choice for both intake and exhaust valves.

Each seal in this set of 16 has an 11/32 inch stem size and a 0.500 inch inside diameter, designed to fit snugly onto your valve stems. Using Viton helps ensure a long service life, even under the demanding conditions found in an engine's cylinder head. This is important because worn-out seals can lead to increased oil consumption, blue smoke from the exhaust, and fouled spark plugs.
