11/32in Valve Stem Seals O-Ring Type

The COMP CAMS 11/32in Valve Stem Seals O-Ring Type are essential components for engine builders and performance enthusiasts focused on precision valve train control. These seals are designed to prevent oil from leaking into the combustion chamber through the valve guides, which helps eliminate blue smoke at startup and ensures proper oil consumption during engine rebuilds.

Featuring an O-ring design that utilizes elastomer compression sealing, these valve stem seals offer superior consistency and a longer service life compared to traditional umbrella-style seals. The 11/32-inch diameter is compatible with many small-block and mid-block valve stem dimensions, making them suitable for various applications, including Chevy LS, small-block Ford, and Mopar engines. Their high-temperature elastomer construction resists heat and oil breakdown, maintaining sealing integrity even in demanding conditions.

These seals are ideal for engine rebuilds and should be replaced during any head gasket job or top-end rebuild to ensure optimal performance. Installation requires cylinder head and valve removal, making it a task best suited for experienced builders and machine shops. Proper selection and installation of valve stem seals are crucial for maintaining engine reliability and cleanliness.
