Product Details

COMP Cams PTFE valve seals are engine valve stem oil seals, also called valve guide seals or valve stem seals. They are made for performance and racing engines. They help control the amount of oil that passes down the valve guide, which reduces oil consumption and helps keep oil out of the combustion chamber.

Key Features:

  • PTFE construction: PTFE holds up to high temperatures and resists wear. It is a common choice for high-performance valvetrain applications.
  • Oil control: The seals meter oil to the valve stem and guide. This helps protect the valve stem and guide while limiting excess oil in the combustion chamber.
  • Made for performance engines: The seals suit street performance, racing and high-RPM builds. They are designed to work with aftermarket valve springs and high-lift camshaft setups.
  • Sold as a seal set: The line covers several valve stem and guide size options, so you can match the seals to your engine build.

COMP Cams has been a well-known name in camshafts and valvetrain components for many years. These PTFE valve seals are a dependable choice when rebuilding or upgrading an engine's valve train. Confirm the valve stem and guide size for your application before ordering.
