Description

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.

  • Semi-flexible, medium-strength anaerobic flange gasket
  • Easy to automate
  • Reduces process costs – eliminates manual assembly of conventional gaskets
  • NSF P1 Reg. No. 123758
  • For active and inactive rigid metal flanges
  • Cures through minor surface contamination
  • Adapts to flange surface irregularities and gaps up to 0.25 mm
  • 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
