LOCTITE® 573 is a high-performance flange sealant ideal for preventing leaks between metal flanges. It cures in the absence of air, forming a tough, flexible seal resistant to oils and fluids, making it perfect for demanding industrial applications.
LOCTITE® 573 is an advanced anaerobic sealant formulated for sealing close-fitting flanges in industrial assemblies. It cures when confined between metal flanges in the absence of air, providing a durable, leak-proof seal. LOCTITE® 573 eliminates the need for traditional gaskets and is resistant to various industrial fluids, including oils, coolants, and fuels.
This sealant is designed to fill gaps between rigid metal flanges and can be used on slightly contaminated surfaces, including those with light oil residues. Its resistance to high temperatures and pressures makes it suitable for a wide range of applications, from automotive to heavy machinery to power generation and chemical processing. LOCTITE® 573 offers a superior gap-filling capabilities, ensuring reliable sealing even on imperfect or misaligned surfaces.
