The ASC Engineered Solutions 1D.NMT is a 1-1/2 inch malleable iron pipe tee with female NPT (FNPT) threads on all three outlets, rated for 150 lb service. This domestically manufactured fitting provides a reliable branch connection in threaded piping systems. The galvanized finish delivers corrosion resistance suited for wet or exposed installations. Plumbers and pipefitters use this tee to split or combine flow in water, gas, and general-purpose piping runs where a threaded malleable iron fitting is required by specification or code.
This fitting is suited for residential and light commercial plumbing, gas distribution, and mechanical piping systems that require a 1-1/2 inch threaded branch connection. The 150 lb pressure rating meets common requirements for low-pressure steam, water, and gas lines. Its FNPT threads on all three ports accept standard NPT male pipe ends, making it compatible with typical Schedule 40 pipe assemblies in new construction and retrofit work.
Designed as an OEM-style replacement or new-installation fitting for threaded malleable iron piping systems using 1-1/2 inch NPT pipe.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and IFGC requirements for gas service. Shut off and depressurize the piping system completely before disassembly or fitting installation. Apply an appropriate pipe thread sealant or PTFE tape to the male threads before assembly, and tighten to the fitting manufacturer's standard hand-plus-wrench turns guidance. Do not over-torque malleable iron fittings, as the material can crack under excessive force.
