518 25ml Loctite

Medium strength gasketing

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 and Benefits

• 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 0.25 mm
• Seals instantly against low pressure
• Resists high pressure when fully cured
• Gel-type consistency
• Reduces process costs – eliminates manual assembly of conventional gaskets
• NSF P1 Reg. No. 123758
