Loctite 574 Flange Sealant

Overview

Loctite 574 is a form-in-place, instant-seal anaerobic gasket sealant for close-fitting rigid metal faces and flanges, providing resistance to low pressures immediately after assembly. Its thixotropic formula reduces product migration and is typically used as a form-in-place gasket on gearbox and engine casings.
