Description
Loctite 37397 is LOCTITE® 592, a thick, off-white, anaerobic, PTFE-filled thread sealant paste for metal pipe threads and fittings; it provides immediate low-pressure sealing, prevents galling with high lubricity, allows readjustment shortly after assembly, and seals to pipe-burst pressure after 72 hours, with typical service up to 400 °F (204 °C). It is medium-strength and not recommended for plastic piping.
