Supertech Nissan 7mm Viton Valve Stem Seal - Single

Supertech is known for making well-built engine components, and this single valve stem seal is no exception. This seal is designed for Nissan 7mm valve stems and is made from Viton, a material that holds up well to heat and oil.

When you're rebuilding the top end of your engine, or just replacing worn-out seals, these are a solid option. Viton seals are a good choice because they resist degradation from engine oil and high temperatures, helping to prevent oil from leaking down the valve guides and into the combustion chamber. This particular seal is a direct fit for 7mm valve stems.
