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 0.25mm 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.

Features:

• Semi-flexible, medium-strength anaerobic flange gasket.
• For active and inactive rigid metal flanges.
• Cures through minor surface contamination.
• Adapts to flange surface irregularities and gaps up to 0.25mm.
• Gel-type consistency.
• Seals instantly against low pressure.
• Reduces inventory costs – no need for large inventory of cut gaskets.
• Resists high pressure when fully cured.
• No compression set or misaligned gaskets.
• Easy to automate.
• Reduces process costs – eliminates manual assembly of conventional gaskets.
• NSF P1 Reg. No. 123758.
