The ASC ENGINEERED SOLUTIONS 810040808 is a black malleable iron reducing tee designed for threaded pipe assemblies in plumbing, gas distribution, and mechanical piping systems. The fitting measures 1 inch on the run with 3/4 inch outlets, making it a standard reducing configuration for branch line connections. The black coating provides corrosion resistance suited to dry and low-moisture environments. Licensed plumbers and pipefitters install this type of fitting when transitioning from a main run to a reduced branch line in ferrous pipe systems.
This reducing tee is used in residential and light commercial applications including gas supply lines, compressed air distribution, and black iron steam or water piping. The threaded ends accept standard NPT pipe threads for assembly with a pipe wrench and thread sealant or PTFE tape. It is appropriate for use where a branch takeoff at a reduced diameter is required from a larger main line.
Designed as an OEM-style replacement and standard-use fitting for threaded black iron pipe systems using NPT connections in plumbing and mechanical piping applications.
Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable codes including the IPC and IFGC. Shut off gas or water supply and depressurize the line before disassembly or installation. Apply an appropriate thread sealant or PTFE tape to all male threads before assembly. Do not over-tighten threaded fittings, as malleable iron threads can crack under excessive torque.
