Installation Notes

Installation is performed by a licensed plumber or pipefitter. Shut off and depressurize the piping system completely before removing or installing any threaded plug. Apply an appropriate thread sealant or PTFE tape to the male threads before engagement, following local plumbing code requirements such as the IPC or IFGC where applicable. Do not overtighten; use a pipe wrench with steady, controlled force to seat the plug without stressing the fitting body.
