The ASC Engineered Solutions 810038612 is a black malleable iron reducing tee designed for threaded pipe assemblies in gas, air, and general industrial piping systems. The fitting transitions from a 3/4 inch run to a 1/4 inch branch, allowing techs to tap off a main line without cutting in an additional section. The black oxide coating provides corrosion resistance suited to dry and low-moisture service environments. Malleable iron construction gives the fitting the ductility and thread engagement strength needed for reliable, leak-free connections in demanding trade applications.
This reducing tee is used in residential and light commercial piping work where a threaded branch connection is needed off a 3/4 inch main. Typical applications include gas supply lines, compressed air distribution, and black iron piping systems in mechanical rooms, utility spaces, and equipment pads. It is installed by licensed plumbers, pipefitters, and HVAC technicians as part of new construction or retrofit piping runs.
Designed as an OEM-style replacement and standard-use fitting compatible with threaded black iron pipe systems using NPT connections in 3/4 inch and 1/4 inch pipe sizes.
Installation should be performed by a licensed plumber, pipefitter, or HVAC technician in accordance with applicable codes such as the IFGC or IPC. Shut off and depressurize the line before disassembling any existing fittings. Apply thread sealant or tape rated for the service medium before hand-tightening and then wrenching to a secure fit. Do not over-torque malleable iron fittings, as the material can crack under excessive force.
