The Remflex 11-003 exhaust gasket is made from 100 percent flexible graphite for a high-temperature seal on Oldsmobile V8 400-455 engines. The graphite construction handles continuous exhaust heat up to 3,000 degrees F and uses a built-in 50 percent crush to conform to the flange, filling gaps and surface imperfections up to 1/16 inch. Because the material rebounds against the sealing surfaces as it heats and cools, the gasket keeps its seal without re-torquing.
