Black Rubber PCV Grommet for Aluminum Valve Covers

• Black rubber grommet seals breather, PCV, or plug openings in valve covers

• Sized for a 3/4" ID opening with a 1 1/4" OD and 1/8" groove width

• Fits aluminum valve covers with a matching 3/4" breather-style opening

• Sold individually — a low-cost fix for a worn or missing grommet

The Black Rubber PCV Grommet for Aluminum Valve Covers seals the opening where a breather, PCV valve, oil cap, or plug installs into a compatible aluminum valve cover. Black rubber construction is sized for a 3/4" inside diameter, 1 1/4" outside diameter, and 1/8" groove width, matching the standard PCV-style opening used on many aluminum valve covers.

This grommet is commonly used to replace a worn, cracked, or missing grommet during breather or PCV valve installation or valve cover service, rather than being sold as part of a complete breather or valve cover kit.

Verify your valve cover opening matches the 3/4" ID / 1 1/4" OD / 1/8" groove sizing before ordering, since grommet sizing varies between valve cover styles and manufacturers.

Applications
