The ASC ENGINEERED SOLUTIONS 810042606 is a black-coated malleable iron reducing tee designed for threaded pipe assemblies in plumbing, gas distribution, and mechanical piping systems. The main run measures 1-1/4 inches and the branch outlet measures 3/4 inches, making it a standard reducing configuration used when transitioning between pipe sizes within a distribution line. At 0.92 pounds, this fitting delivers the durability and thread integrity that malleable iron is known for in high-demand trade applications. Licensed plumbers, pipefitters, and mechanical contractors install this type of fitting as part of new construction and retrofit work.
This reducing tee is suited for residential and light commercial piping applications where a threaded black iron fitting is required. Common uses include gas supply lines, steam systems, compressed air distribution, and water piping where the system design calls for a branch takeoff at a reduced diameter. The 1-1/4 inch by 3/4 inch configuration is a frequently specified size in both new installations and repair scenarios where existing piping infrastructure uses standard NPT threaded connections.
Designed as an OEM-style replacement or new-installation fitting for threaded black malleable iron piping systems using standard NPT connections.
Installation should be performed by a licensed plumber or pipefitter following applicable local codes, including IFGC requirements for gas piping applications. Shut off and depressurize the system completely before disassembling or adding to any piping run. Apply an approved thread sealant or PTFE tape to all male threads before makeup. Do not over-tighten threaded fittings, as malleable iron threads can crack under excessive torque.
