The ASC Engineered Solutions 310050406 is a black malleable iron reducing tee designed for threaded pipe assemblies in gas, steam, and water distribution systems. Manufactured domestically from malleable iron with a black coating, this fitting connects a 2-inch run pipe to a 1-1/2-inch outlet and a 1-inch branch, allowing three-way flow direction changes with inline diameter reductions. Weighing 1.57 pounds, it is sized for use in moderate- to heavy-duty piping configurations. Licensed pipefitters and plumbers install this fitting in commercial and residential mechanical systems where threaded iron pipe is the specified material.
This reducing tee is suited for threaded black iron piping systems used in natural gas distribution, low-pressure steam heating, compressed air lines, and potable or non-potable water supply. The domestic manufacturing designation indicates the fitting meets domestic production standards. Its 2-inch by 1-1/2-inch by 1-inch configuration makes it appropriate for headers, branch takeoffs, and distribution manifolds where simultaneous run reduction and branch sizing are required in a single fitting.
Designed as an OEM-style replacement or new-install fitting for threaded black malleable iron pipe systems using standard NPT connections.
Installation should be performed by a licensed plumber or pipefitter following applicable IPC or IFGC requirements for the intended service. Shut off and depressurize the piping system completely before disassembling any threaded connections. Apply appropriate thread sealant or PTFE tape to male threads before assembly and tighten to hand-tight plus wrench turns per pipe trade practice. Do not over-torque, as malleable iron fittings can crack under excessive force.
