What Type of Gasket Material Is Used Around Gasoline?

by Derek Wray

The type of gasket material used around gasoline depends upon the specific application. Automotive fuel injectors use rubber o-rings and so do many other fuel system components. For automotive purposes, there are three common examples of fuel resistant gasket materials:

Nitrile bonded cork gasket material is gasoline resistant and acceptable for use in some automotive applications.

Rubber coated paper gasket material can be used for carburetor float bowl and other applications where fuel resistance is required.

Fuel resistant gasket dressing can be used on applications when a gasket requires a sealant added for extra fuel resistance.

Warnings

Silicone sealants are not recommended for use in a gasoline environment. The gasoline will attack the product.
