Loctite 542 Thread Sealant for Metal Fittings 50 ML

LOCTITE®
542 is designed for the locking and sealing of metal
pipes and fittings. The product cures when confined in the
absence of air between close fitting metal surfaces and
prevents loosening and leakage from shock and vibration. The
thixotropic nature of LOCTITE®
542 reduces the migration of
liquid product after application to the substrate.
