Seal, HD OE Style, 3/8" Stem X 0.625" Guide Seal Detail, HD®, Shovelhead™ 80", 1978-1983 (Pkg. of 4)
These OE style seals incorporate a special low friction graphite impregnated PTFE sealing element. PTFE material does not have “memory” and therefore is subject to creep. Creep allows the seal to conform to mating surfaces, controlling oil, but not letting the parts run dry. PTFE is known to retain its mechanical properties at temperatures as high as 500°F. These steel clad seals have a low profile for seal-to-retainer clearance, and will fit inside dual spring assemblies.
