Sealing Solutions Since 1967
Made from Closed Cell Nitrile (Buna-N), C43NBR is a firm density, black sponge material that is used for indoor and outdoor sealing applications requiring oil, fuel, and UV resistance. With a density of 10lbs/ft³, C43NBR is an excellent gasket material in petroleum-based applications, resisting vegetable oil, animal oil, mineral oil, and other aromatic hydrocarbons.
Closed Cell Nitrile Sponge can be supplied with or without adhesive and will maintain its properties and structure in temperatures from -40 to 250°F (-40 to 121°C). C43NBR also passes the flammability standard of FMVSS-302.
