Loctite® 518 cures when confined in the absence of air between close fitting metal surfaces. It is an anaerobic gasketing material designed for use on rigid iron, aluminum and steel flanged mating surfaces. Loctite® 518 fills gaps up to 0.25 millimeters and forms a flexible, chemical-resistant seal that will not tear or decay. Parts disassemble easily, even after extended service. Typical applications include sealing close fitting joints between rigid metal faces and flanges. It is also used as a formed in place gasket on rigid flanged connections, e.g. transmissions and motor housings.
