This assortment is suited for residential and light commercial applications involving 1/2 inch black iron pipe. Typical install scenarios include natural gas and propane supply lines, as well as steam and air distribution systems where black iron fittings meet code requirements. The imported iron construction makes this pack a practical option for general service and maintenance stock.
Designed as an OEM-style replacement and service fitting for standard 1/2 inch black iron pipe systems used in gas supply, steam, and industrial piping applications.
Black iron nipple fittings are typically installed by licensed plumbers or gas fitters following local mechanical codes and IFGC requirements. Always shut off the gas supply and verify zero pressure at the line before disassembling or installing any fitting. Apply an approved pipe thread sealant or PTFE tape rated for gas service to all threaded connections. Pressure test all connections after installation per applicable local code before returning the system to service.
