This fitting connects three sections of pipe in a branch configuration, directing flow from a main run to a lateral outlet. It is used in black iron piping systems for gas distribution, steam, and industrial fluid conveyance. The nominal size is 1 x 3\/4 x 1 inches, making it a reducing tee with a 3\/4-inch branch off a 1-inch run. Plumbers, pipefitters, and gas line technicians are the primary installers of this fitting class.\u003c\/p\u003e\n\u003cp\u003eThis tee is suited for residential and light commercial applications including natural gas and propane distribution lines, steam heating systems, and low-pressure air or fluid piping. The 150 lb pressure rating covers standard service conditions found in most building mechanical systems. The black oxide finish provides corrosion resistance appropriate for interior dry piping and is standard on gas-line fittings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMalleable iron construction provides strength and thread engagement superior to cast iron in threaded connections\u003c\/li\u003e\n  \u003cli\u003e150 lb pressure class rated for standard-service gas, steam, and fluid systems\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish standard for interior gas and steam piping applications\u003c\/li\u003e\n  \u003cli\u003eReducing tee configuration: 1-inch run, 3\/4-inch branch, 1-inch outlet\u003c\/li\u003e\n  \u003cli\u003eThreaded NPT connections compatible with standard black iron pipe and fittings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-installation fitting for 150 lb threaded malleable iron piping systems using standard NPT pipe threads.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or pipefitters in accordance with applicable codes such as the IFGC for gas systems or the IPC for water and steam systems.
