These OE-style valve guide seals feature a low-friction, graphite-impregnated PTFE sealing element engineered to conform to mating surfaces and manage oil flow without letting parts run dry. The durable PTFE material maintains its mechanical integrity at temperatures up to 260°C (500°F) for dependable performance in demanding conditions.

Designed with steel cladding, these low-profile seals provide exceptional seal-to-retainer clearance and fit neatly inside dual spring assemblies. They offer direct compatibility for classic Harley-Davidson Panhead and Shovelhead engine builds.
