KIBBLEWHITE Seal Valve — 3/8" stem, 4-pack – 57-83 Sportster

These valve seals are high-quality components manufactured for long-term reliability. The OE-style intake seals use a low-friction, graphite-impregnated PTFE sealing element that minimizes wear and improves sealing performance.

PTFE does not have memory and is therefore subject to creep; this allows the sealing element to conform to mating surfaces, controlling oil without letting parts run dry. PTFE retains mechanical properties at temperatures up to 500° F.

The steel-clad, low-profile design provides seal-to-retainer clearance and fits inside dual spring assemblies. Typical measurements include stem diameter 3/8", overall length 0.400", seal O.D. 0.720" and guide diameter 0.625". 🔧
