What is Loctite 573 used for?

You use it to seal close-fitting joints between rigid metal faces and flanges, such as gearboxes and engine casings.

How does this flange sealant cure?

It cures anaerobically, which means it hardens in the absence of air when confined between close-fitting metal surfaces.

What is the maximum gap size for Loctite 573?

This sealant is designed for close-fitting flange parts with gaps up to 0.25 mm.

Why choose Loctite 573 for complex assemblies?

Its slow cure rate allows you ample time to align and assemble large or intricate flanges without premature curing.

Which fluids is this sealant resistant to?

It offers high resistance to common industrial fluids, engine oils, transmission fluids, and water.
