COMP Cams Positive-Stop PTFE valve seal fits 3/8" valve stems and .500" valve guides, with a .600" outer diameter. These PTFE seals provide better sealing than O-ring or umbrella designs while offering extra clearance for dual-spring setups. Their smaller diameter compared with COMP umbrella seals allows use with double springs without sacrificing control of oil entering the combustion chamber.
