Permatex® Anaerobic Gasket Maker OEM specified. Non-corrosive gasketing material designed primarily for use on aluminium, iron, and steel flanged mating surfaces. Ideal when a conventional gasket is unavailable (not for use with conventional gaskets). Fills gaps up to 0.38mm and cures to a solvent-resistant seal that will not tear or decay during service. Parts disassemble easily even after extended service. Old gasket material can be removed in minutes with the Permatex Safer Scraper. Suggested Applications: For use on machined aluminium metal components; transmission pans, transmission case covers, transaxle casings, transfer cases, split crankcases, pumps, and housings.
