Loctite® 518

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 flexibility.
