Supertech Nissan 7mm Viton Valve Stem Seal - Set of 8

Made from Viton, these 7mm valve stem seals from Supertech are built to handle the heat and stress inside your Nissan engine. Viton is a high-performance fluoroelastomer known for its excellent resistance to oil, fuel, and high temperatures, making it a solid choice for keeping oil out of your combustion chambers. This set includes eight seals, enough for a typical four-cylinder engine, ensuring you have what you need for a complete valve job or rebuild.

Properly sealing your valve stems is crucial for maintaining engine performance and preventing excessive oil consumption. When these seals wear out, oil can seep past the valve guides and burn in the combustion chamber, leading to blue smoke from the exhaust, fouled spark plugs, and reduced engine efficiency. Replacing them with well-built Viton seals like these can help restore your engine's health and keep it running smoothly.
