Loctite LOC37127 Pipe Thread Sealant 19 Gm Tube

Product Description

The LOCTITE LOC37127 is a pipe thread sealant supplied in a 19 gram tube, formulated for sealing threaded pipe connections in plumbing and mechanical systems. This anaerobic sealant cures in the absence of air when confined between metal threads, locking and sealing fittings against leaks from the first assembly. It is suited for use on metal and compatible plastic fittings and is typically applied by licensed plumbers, pipefitters, and HVAC technicians working on low- to medium-pressure systems. The compact tube format allows precise application and reduces waste on smaller jobs or service calls.

This thread sealant is appropriate for residential and light commercial plumbing, gas distribution, hydronic heating, and HVAC refrigerant line connections where a reliable, pressure-resistant pipe seal is required. The PST 561 formulation is designed for use on metal pipe threads including steel, stainless, and brass fittings commonly found in service and new-construction applications.

Installation Notes

Application is typically performed by a licensed plumber, pipefitter, or HVAC technician. Shut off system pressure and depressurize the line before disassembling or reassembling any threaded connection. Clean threads of oil, debris, and old sealant before applying a uniform bead of sealant to the male threads. Allow adequate cure time before returning the system to service pressure, following the sealant manufacturer guidelines and applicable code requirements such as the IPC or IFGC.
