Installation Notes

Installation is performed by a licensed plumber or pipefitter following applicable IPC or IFGC requirements for the service type. Depressurize and isolate the line before installing or removing any pipe plug. Apply thread sealant or PTFE tape appropriate for the service medium — consult the sealant manufacturer for compatibility with gas or fuel applications. Use a properly sized wrench on the square head; do not use pliers directly on the brass body to avoid deforming the fitting.
