The ASC Engineered Solutions 810044008 is a black malleable iron reducing tee designed for threaded pipe assemblies in gas, air, and industrial fluid distribution systems. The fitting connects a 1-1/4 inch run on both ends with a 3/4 inch branch outlet, making it a standard reducing tee configuration used when a branch line steps down from the main run. The black oxide coating provides corrosion resistance suitable for dry or low-moisture environments. Weighing 1 pound, this import fitting is sized for common commercial and light industrial piping layouts where NPT-threaded malleable iron fittings are specified.
This fitting is used in threaded black iron pipe systems commonly found in commercial gas distribution, compressed air lines, and industrial process piping. Plumbers, pipefitters, and mechanical contractors install this type of fitting when routing a branch off a main 1-1/4 inch line while reducing the branch to 3/4 inch. The malleable iron construction handles the mechanical stress of field assembly and disassembly better than cast iron, making it a standard choice in service and retrofit work.
Designed as an OEM-style replacement or new-installation fitting for 1-1/4 inch threaded black iron pipe systems using standard NPT connections.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and fuel gas codes, including IFGC and ASME B31 standards where required. Shut off all gas or fluid supply and relieve system pressure before disassembling or threading new fittings. Apply an appropriate pipe thread sealant or PTFE tape rated for the service medium to all male threads before assembly. Do not over-tighten threaded connections, as malleable iron fittings can crack under excessive torque.
