COMP Cams Valve Stem Oil Seal Guide Stem Metal Viton

COMP Cams Viton metal body valve stem oil seals, also called valve seals or valve stem seals, keep unwanted oil out of the combustion chamber. They block oil that would otherwise seep through the clearance in the valve guides. They suit performance engine builds where oil control, valve spring clearance and long-term durability matter.

Key Features:

• Viton fluoroelastomer sealing material: Resists heat, oil additives and abrasion. It gives better sealing than factory O-ring style seals.
• Metal body construction: Keeps the seal firmly in place for long-term durability.
• Compact outside diameter: Gives more clearance for performance dual and beehive valve springs. It also suits applications where inner spring clearance is limited.
• Guide-mounted design: These seals attach to the valve guide instead of riding on the valve. The guide typically needs machining, so check the instructions for your seal before installing.
• Made in the USA: Built to COMP Cams quality standards.

The COMP Cams valve seal line covers a range of valve stem and valve guide configurations. Choose the variant that matches your valve stem diameter and guide outside diameter. A precision seal installation tool is available from COMP Cams or Powerhouse to help with installation.

COMP Cams has built valve train components since 1976. These seals help improve oil control and engine efficiency in street, racing and high-performance builds.
