Loctite 518 General purpose, semi-flexible sealant for rigid flanges

  • Loctite 518
  • LOCTITE® 518 is a general purpose, primer less, semi-flexible, form-in-place anaerobic flange sealant.
  • It cures – even in the presence of minor surface contaminants – to seal close fitting joints between rigid metal flanges, and will flex with minor flange movements.
  • It provides resistance to low pressures immediately after assembly of flanges, and is ideal for use on aluminum substrates where you need very good flexibility.
  • Typically used as a form-in-place gasket for pumps, thermostats, compressors, transmission housings and axle covers, it not only works on active metals (e.g. mild steel) but also on passive substrates, such as aluminum with a low copper content.
  • You can expect gap performance to 0.25 mm (0.01″).
  • Semi-flexible anaerobic flange sealant
  • Adapts to surface irregularities and gap fill up to 0.25 mm (0.01″)
  • Forms an instant low-pressure seal
  • Cures on inactive surfaces without primer
  • NSF registered
