COMP Cams 11/32" umbrella valve seal is part of a complete valve stem seal range and is used to keep oil from entering the combustion chamber through valve guide clearance. The umbrella style is intended for larger‑diameter spring installations and normally requires no machining. COMP also supplies O‑ring, positive‑stop PTFE, and smaller Viton seals for other spring and guide setups.
