Cometic HTG exhaust gasket set for Oldsmobile 400/425/455 features .094in thickness with 1.920in x 1.550in rectangular ports. These HTG gaskets use a mechanically bonded graphite/fiber facing on a perforated stainless core for heat and sealing resilience. The facing contains graphite with Kevlar fiber reinforcements for durability, and the asbestos-free construction suits older V8 exhaust flanges needing reliable sealing without additional sealants.
