Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, IPC, and IFGC requirements. Shut off and depressurize the pipe system completely before removing or installing any union fitting. Apply appropriate thread sealant rated for the service type — liquid, gas, or steam — to all threaded connections before assembly. Do not overtighten threaded joints; use a pipe wrench with proper support to avoid stressing adjacent fittings or pipe sections.
