Gasketing Product - general purpose. Ideal for use on machined and rigid metal flanges
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. It provides resistance to low pressures immediately after assembly. Typically used as a form-in-place gasket on rigid flanged connections. The nature of LOCTITE® 574 reduces the migration of liquid product after application to the substrate. It has a high oil tolerance and excellent water and glycol resistance.
