The ASC ENGINEERED SOLUTIONS 300048402 is a black cast iron reducing tee designed for threaded pipe systems. It connects a 2-inch run pipe to a 1-1/4-inch branch outlet while maintaining a 2-inch through passage, making it a reliable choice for reducing branch connections in drainage, waste, and vent (DWV) or low-pressure piping systems. Weighing 3.49 pounds, this domestically produced fitting delivers the mass and durability expected from cast iron in demanding service environments. Licensed plumbers and pipefitters install this fitting as part of threaded iron pipe assemblies in both new construction and retrofit work.
This reducing tee is suited for residential and light commercial plumbing applications where threaded cast iron pipe assemblies are specified. The 2 x 1-1/4 x 2-inch configuration handles branch takeoffs from a main 2-inch line, directing flow to a reduced 1-1/4-inch branch. It is commonly used in above-grade drain and supply rough-in work, mechanical room piping, and industrial process lines where cast iron threaded fittings are the material of choice.
Designed as an OEM-style replacement and standard threaded fitting for use with 2-inch and 1-1/4-inch black iron threaded pipe assemblies in plumbing and mechanical piping systems.
Installation is performed by a licensed plumber or pipefitter following applicable IPC and local mechanical code requirements. Shut off the water supply or isolate the pipe segment before cutting into an existing line. Apply an approved thread sealant or PTFE tape to all male threads before assembly, and tighten with pipe wrenches to achieve a leak-free joint. Do not over-torque cast iron threaded fittings, as the material is brittle and susceptible to cracking under excessive force.
