LOCTITE® 518
Features and Benefits
Available sizes:
This general purpose, semi-flexible anaerobic-curing gasketing product is ideal for sealing close fitting, rigid machine flanges made of aluminium, iron or steel.
LOCTITE® 518 is a general purpose, primerless, 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 aluminium 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 aluminium with a low copper content. You can expect gap performance to 0.25mm.
- 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
- 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
