The ASC Engineered Solutions 310049606 is a black malleable iron reducing tee designed for threaded pipe assemblies in plumbing, HVAC, and industrial piping systems. This domestically manufactured fitting connects a 2-inch run pipe with a 1/2-inch branch outlet, allowing flow direction changes and branch takeoffs in a single fitting. The black coating provides corrosion resistance suited for gas distribution, compressed air lines, and general-purpose black iron piping systems. Licensed plumbers, pipefitters, and HVAC technicians install this type of fitting wherever a reducing branch connection is required on threaded iron pipe.
This reducing tee is used in residential and light commercial applications where black iron pipe is the specified material. Common installation scenarios include natural gas supply lines, propane distribution, steam systems, and fire protection branch lines. The 2-inch by 1/2-inch size ratio makes it a practical choice for main-line runs that require a smaller-diameter branch takeoff for appliance connections or instrument taps.
Designed as an OEM-style replacement and standard-stock fitting for 2-inch by 1/2-inch NPT threaded black iron pipe systems in residential and commercial plumbing, HVAC, and gas piping installations.
Installation of black malleable iron fittings should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable local codes, the International Fuel Gas Code (IFGC), and the International Plumbing Code (IPC). Shut off and depressurize the line before disassembly or assembly of any threaded fitting. Apply appropriate thread sealant or PTFE tape rated for the intended service medium to all male threads before assembly. Do not over-tighten threaded connections, as malleable iron fittings can crack under excessive torque.
