LOCTITE® 592 is a thick, white, anaerobic-curing lubricating thread sealant paste, which prevents leaks and galling on pipe threads and fittings. It provides immediate low-pressure sealing and allows the readjustment of fittings shortly after assembly. The joint seals against pipe burst pressure after 72 hours. Suits applications up to 204°C (400°F). Unsuitable for plastic piping.
