Permatex Anaerobic Gasket Maker is designed primarily for use on aluminum, iron, and steel flanged mating surfaces. This non-corrosive gasketing material is ideal for on-the-spot and emergency repairs, or when a conventional gasket is unavailable. Fills gaps up to .015 inches and cures to a solvent-resistant seal that will not tear or decay during service. Parts disassemble easily even after extended service and old gasket material can be removed in minutes with a simple putty knife. Suggested applications include water pumps, thermostat housings, transmission pans, transmission case covers, transaxle casings, and o-ring replacement.
