COMP Cams 11/32" umbrella valve seal fits 11/32" valve stems with OE‑size guides (.750" OD) and prevents oil migration past the valve guides. Normally used with larger‑diameter springs, this umbrella seal typically requires no machining and serves as a practical replacement option for stock guide applications where spring size or seal condition necessitates a new seal.
