ST. LOUIS — Nu-Calgon has launched NuLock™, a family of anaerobic-based products designed for metal fastener thread locking and sealing in the HVACR market.

NuLock is available in multiple formulations for different applications:

1)         A general purpose thread sealant for metal fasteners;

2)         A thread sealant for refrigerant systems;

3)         A thread sealant with PTFE for metal threaded pipes and fittings; and
