LOCTITE® 574 seals close-fitting joints between rigid metal faces and flanges. The product cures when confined in the absence of air between close-fitting metal surfaces. It provides resistance to low pressures immediately after assembly. Typically used as a form-in-place gasket on rigid flanged connections. The nature of LOCTITE 574 reduces the migration of liquid product after application to the substrate. It has a high oil tolerance and excellent water and glycol resistance.

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 mm 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.
