The ND INDUSTRIES 42050 is an industrial-grade anaerobic thread sealant designed to lock and seal threaded fasteners in demanding service environments. Supplied in a 50 ml tube, this white-colored compound cures in the absence of air to create a durable seal that resists loosening caused by shock and vibration. Rated for high-temperature applications, the 42050 is a go-to solution for licensed plumbers, pipefitters, HVAC technicians, and industrial maintenance professionals who need a reliable, chemical-grade alternative to mechanical locking hardware on threaded connections.
This sealant is suited for use on metal threaded pipe joints, fastener assemblies, and fittings found in residential and commercial HVAC systems, plumbing installations, and general industrial equipment. It is applied directly to male threads before assembly, filling the gaps between mating surfaces to prevent fluid or gas leakage while simultaneously locking the connection against vibration-induced loosening. The white formulation allows for visual confirmation of application coverage during installation.
Designed as an industrial-grade thread sealant and locker for use on metal threaded fasteners and pipe connections in HVAC, plumbing, and general industrial assemblies.
Applied by licensed plumbers, pipefitters, or HVAC technicians as part of a standard threaded assembly procedure. Clean and degrease mating threads before application to ensure proper cure and adhesion. Apply the compound to the male threads, assemble immediately, and allow adequate cure time before pressurizing or returning the system to service. Refer to applicable IPC or IFGC code requirements for sealant use on gas and fluid-carrying pipe systems.
