Supertech Nissan 6mm Viton Exhaust Valve Stem Seal - Set of 12

If you're rebuilding the top end of your Nissan engine, these Supertech valve stem seals are a solid choice. They're made from Viton, a material known for its excellent resistance to heat and oil, which is exactly what you need where the valve stem meets the head. This set includes 12 seals, enough for a typical 6-cylinder engine, ensuring you have what you need to keep oil from leaking down the valve guides.

These seals are designed to fit 6mm valve stems, a common size in many Nissan engines. Viton is a durable material that holds up well in high-temperature environments, helping to prevent premature wear and oil consumption. Installing new valve stem seals is a key step in ensuring your engine runs cleanly and efficiently, especially after a rebuild or if you're experiencing oil burning issues.
