Loctite 574 Instant Gasket Sealant 50 ML

LOCTITE®
574™ seals close fitting joints between rigid metal
faces and flanges. The product cures when confined in the
absence of air between close fitting metal surfaces. Provides
resistance to low pressures immediately after assembly of
flanges. Typically used as a form-in-place gasket on rigid
flanged connections, e.g. gearbox and engine casings, etc.
The thixotropic nature of LOCTITE®
574™ reduces the
migration of liquid product after application to the substrate.
