Detailed Description

Fel-Pro 70800 is an engine crankcase vent O-ring used in emission control and sealing system service. Fel-Pro gaskets are engineered for vehicle-specific sealing performance, using materials selected for the application rather than a one-size-fits-all approach. This makes the part a practical choice when servicing crankcase vent connections on vehicles such as Chevrolet Camaro, Pontiac Firebird, Buick Regal, and Oldsmobile Cutlass Supreme.

This part cross-references Dorman - HELP 79101 and MAHLE B25934 for the same application. The Fel-Pro 70800 part number is also commonly referenced in sealing and gasket catalogs for related service work.
