Loctite 237051 542 is designed for locking and sealing metal pipes, fittings, and other cylindrical metal assemblies. The product cures when confined in the absence of air between close-fitting metal surfaces, preventing loosening and leakage caused by shock and vibration. The thixotropic nature of Loctite 542 reduces the migration of the liquid product after application to the part.
