LoctiteåÂ 5203 Flange Sealant seals close fitting joints between rigid metal faces and flanges. Provides resistance to low pressures immediately after assembly of flanges. TheÌ_ product cures rapidly when confined in the absence of air between close fitting metal surfaces. Fully cured product can easily be removed from flange faces, particularly on aluminum.
Typically used as a form-in-place gasket on rigid flanged connections, e.g. gearbox and engine casings, etc. The thixotropic nature of Loctite 5203 reduces the migration of liquid product after application to the substrate.
