Loctite 574 Flange Sealant
Loctite 574 is a fast curing flange sealant designed for sealing close fitting joints between rigid metal faces and flanges. Loctite 574 cures in the absence of air between close fitting metal surfaces and provides a low-pressure seal straight after assembly. Once applied to the part Loctite 574 will not run as it maintains its viscosity in static conditions.

What Are The Benefits of a Flange Sealant?
Flange sealants prevent the leakage of fluids and gases in machine parts or pipe connections. The sealant also strengthens the assembly and prevents corrosion. The liquid form of the sealant enables surface voids and irregularities to be filled. Once cured flange sealants are able to resist displacement and will not shrink, crack or relax like conventional gaskets
