The ASC ENGINEERED SOLUTIONS 1XD.NMT is a malleable iron reducing tee designed for threaded pipe assemblies in gas, water, and general plumbing distribution systems. It features female NPT (FNPT) threads on all three outlets and is rated for 150 lb service pressure, making it suitable for standard commercial and residential piping installations. The tee reduces from a 1-inch run on both the straight-through ports down to a 1/2-inch branch outlet. A hot-dip galvanized finish provides corrosion resistance for both interior and exterior applications. Licensed plumbers and pipefitters are the primary installers of this fitting.
This reducing tee is used in residential and light commercial plumbing, hydronic heating, compressed air, and gas distribution piping where a branch takeoff at a reduced diameter is required. The 1 x 1 x 1/2-inch configuration is one of the most common reducing tee sizes in low-pressure pipe systems. Domestic manufacture supports projects with Buy American or domestic-content requirements.
Designed as an OEM-style replacement or new-install fitting for standard 150 lb malleable iron threaded pipe systems using NPT connections.
Installation is performed by a licensed plumber or pipefitter in accordance with applicable plumbing codes such as the IPC or IFGC. Shut off and depressurize the pipe system completely before cutting into an existing line or removing any fittings. Apply an appropriate thread sealant or PTFE tape to all male threads before assembly. Do not over-torque threaded connections, as malleable iron fittings can crack if excessive force is applied.
