The ASC Engineered Solutions 311050801 is a galvanized malleable iron reducing tee designed for threaded pipe systems in plumbing, HVAC hydronic, and industrial piping applications. The fitting connects a 2-inch run to a 1-1/4-inch branch outlet with a 1-1/2-inch inlet, allowing flow to be redirected or split across different pipe sizes in a single fitting. The galvanized coating provides corrosion resistance for wet or damp service environments. At 2 pounds, the malleable iron construction delivers the durability and thread integrity required for pressure-rated installations. Licensed plumbers and pipefitters are the typical installers for this type of fitting.
This reducing tee is suited for residential and light commercial piping systems where transitions between pipe sizes are needed at a branch point. Common applications include water supply lines, hydronic heating distribution piping, steam systems, and general-purpose threaded iron pipe assemblies. The domestic manufacturing origin makes it a reliable choice for projects requiring domestically produced components. The reducing configuration eliminates the need for additional bushings in many standard transition scenarios.
Designed as an OEM-style replacement or new-installation fitting for standard NPT threaded malleable iron pipe systems. No specific model or system compatibility data was provided in the product input.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or local plumbing codes. Shut off and depressurize the supply line before removing or installing any threaded fittings. Apply an approved pipe thread sealant or PTFE tape to male threads before assembly, and tighten to a firm, wrench-tight connection without over-torquing malleable iron threads. Inspect all joints for leaks after restoring pressure to the system.
