Product Details

COMP Cams Metal Body Viton Valve Seals are performance valve stem oil seals (also called valve guide seals or valve seals). They control oil at the valve stem and help keep oil out of the combustion chamber. Each set is made for a specific valve stem and guide combination. Viton valve seals suit performance engine builds and are a step up from standard rubber seals.

Key Features:

  • Viton sealing material: Resists heat, oil and chemicals, so the seal holds up under the demanding conditions inside a performance engine.
  • Metal body construction: Gives the seal a secure, durable fit on the valve guide.
  • Spring clearance: The compact seal design gives more room for performance valve springs, including dual and beehive styles.
  • Oil control: Helps reduce oil consumption and protect the valve guides from wear.
  • Made in the USA by COMP Cams, a respected name in camshafts and valvetrain components.

These seals are a common upgrade in street performance, racing and engine rebuild projects. Choose the variant that matches your valve stem diameter and valve guide size.
