COMP Cams 11/32" umbrella valve seal fits 11/32" valve stems with OE‑size guides (.750" OD) and prevents oil from passing the valve guide clearance. The umbrella style is normally used when a larger‑than‑stock diameter spring is installed and typically requires no machining, making it a convenient replacement for stock guide applications that need a reliable seal upgrade.
