The ASC Engineered Solutions 1.NMT is a 1-inch malleable iron pipe tee with female NPT (FNPT) connections on all three outlets, rated for 150 lb service. Constructed from domestic galvanized malleable iron, it provides corrosion resistance and durability in threaded piping systems. This tee is used to split or combine flow in a run of pipe, forming a branch at a 90-degree angle to the main line. It is a standard fitting type installed by licensed plumbers and pipefitters across a wide range of commercial and residential applications.
This tee is suited for use in gas distribution, water supply, and general-purpose piping systems where 150 lb rated threaded fittings are specified. The galvanized finish makes it appropriate for mildly corrosive environments and exposed piping runs. It is a commonly specified fitting in new construction, retrofit, and repair work in both residential and light commercial settings.
Designed as an OEM-style replacement or new-installation fitting for 1-inch threaded malleable iron piping systems rated at 150 lb service class.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and standards such as the IPC or IFGC depending on service type. Shut off and depressurize the piping system fully before removing or installing any threaded fittings. Apply appropriate thread sealant or PTFE tape to all male threads before assembly. Do not over-torque threaded connections, as this can crack the fitting body.
