Valve Seals 11/32 PTFE .500 Guide

The Valve Seals 11/32 PTFE .500 Guide from ALLSTAR PERFORMANCE are precision components designed for high-performance engine builds where valve guide wear and combustion blowby demand a reliable seal. These seals are essential for mechanics and engine builders who are either restoring classic small-blocks or preparing race engines.

Featuring an 11/32-inch bore diameter and a .500-inch guide specification, these valve seals ensure a snug fit that prevents oil from leaking into the combustion chamber. Made from PTFE (polytetrafluoroethylene), they offer excellent thermal stability and low friction, maintaining their performance across varying temperatures.

Ideal for engine builders restoring worn cylinder heads or tuners upgrading original equipment, these valve seals are compatible with small-block Chevy, Ford 289/302, and equivalent platforms. Their compact design allows for easy installation during top-end assembly, making them a reliable choice for enhancing engine performance.
