Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, including the International Plumbing Code and International Fuel Gas Code where relevant. Depressurize and isolate the pipe section before installing or removing threaded plugs. Apply an approved thread sealant or PTFE tape to the NPT threads before engagement. Do not overtighten, as this can damage the fitting or the receiving threaded port.
