Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable local codes and IFGC or IPC requirements depending on service type. Shut off gas or liquid supply and depressurize the line before installing or removing any threaded plug. Apply appropriate thread sealant or tape rated for the service medium before threading the plug into the port. Do not over-tighten; use a proper fitting wrench on the square head to achieve a secure, leak-free connection.
