Asc Engineered Solutions 1DX1B.BMT Malleable Iron Reducing Tee

Product Description

The ASC ENGINEERED SOLUTIONS 1DX1B.BMT is a black malleable iron reducing tee rated for 150 lb service, threaded with female NPT (FNPT) connections on all three ports. The run measures 1-1/2 x 1-1/2 inches and the branch reduces to 1-1/4 inches, making it a standard branch-reduction fitting for gas, air, and compatible fluid piping systems. Domestically manufactured, this fitting is used where a smaller branch tap is required without replacing the main run piping. Plumbers, pipefitters, and mechanical contractors install this fitting in both residential and light commercial applications.

The 1DX1B.BMT suits branch connections in natural gas distribution lines, compressed air systems, steam systems rated within the 150 lb pressure class, and general-purpose black iron piping assemblies. Its FNPT threading accepts standard NPT-threaded nipples and male-end fittings, enabling straightforward integration into existing black iron pipe infrastructure. This fitting is commonly used in boiler rooms, mechanical rooms, and gas service rough-in work.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes, including the International Fuel Gas Code (IFGC) and International Plumbing Code (IPC) where applicable. Shut off and depressurize the pipe system completely before disassembling any fittings or making new connections. Apply listed pipe thread sealant or PTFE tape rated for the intended service medium to all male NPT threads before assembly. Do not over-tighten threaded connections in malleable iron fittings, as the material can crack under excessive mechanical force.
