Vc Pcv Grommet

The VC PCV Grommet by TRANS-DAPT (MPN 4998) is a precision engine ventilation component designed for crankcase evacuation systems in automotive applications. This rubber grommet serves as a critical seal and mounting point in positive crankcase ventilation (PCV) systems, protecting against oil vapors and preventing engine pressure buildup. Whether you're performing routine maintenance, rebuilding an engine, or upgrading an existing PCV setup, this grommet ensures a secure, leak-free connection in your emission control network.

Engineered from durable black rubber, the VC PCV Grommet features a 0.75-inch inner diameter (ID) and 1.25-inch outer diameter (OD) with a 0.672-inch thickness, providing a secure fit for standard PCV tubing and valve configurations. The robust rubber construction resists heat, oil exposure, and vibration degradation common in engine bay environments, maintaining its seal integrity over thousands of operating hours. This design allows controlled venting of crankcase pressure while preventing backflow and external contamination—essential for proper engine breathing and longevity.

Technicians and DIY enthusiasts rebuilding classic or performance engines rely on TRANS-DAPT PCV grommets to restore original factory specifications or adapt aftermarket systems. The grommet's compact dimensions (2.7 x 1.2 x 3.75 inches) and lightweight profile (0.06 lbs) make installation straightforward in tight engine compartments. Replace worn or cracked grommets to prevent vacuum leaks, oil seepage, and performance loss—compatibility spans numerous domestic and imported platforms using standard 0.75-inch ID PCV tubing.
