The ASC Engineered Solutions 810040006 is a black malleable iron reducing tee designed for threaded pipe assemblies in plumbing, gas distribution, and mechanical piping systems. This fitting connects a 1-inch run with a 1/2-inch branch outlet, allowing branch takeoffs in low-pressure gas, air, or water systems. The black oxide coating provides corrosion resistance suitable for dry and semi-dry service environments. At 0.61 pounds, the fitting is a standard-weight threaded tee intended for installation by licensed plumbers, pipefitters, and HVAC technicians working with black iron pipe systems.
This reducing tee is commonly used in residential and light commercial applications including natural gas and propane distribution lines, compressed air headers, fire suppression rough-in, and hydronic heating supply and return branches. The 1-inch by 1/2-inch reducing configuration is a frequently specified size for branch drops off a main gas trunk line or compressed air distribution loop. Installers typically use this fitting where a full-size run must be maintained while supplying a smaller-diameter branch circuit.
Designed as an OEM-style replacement or standard stock fitting for threaded black iron pipe systems using NPT connections in residential and commercial plumbing and gas piping applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) where required. Shut off and depressurize the line before cutting into any existing system. Apply an approved pipe thread sealant or PTFE tape rated for the intended service medium to all male threads before assembly. Do not over-tighten threaded connections in malleable iron fittings, as the material can crack under excessive torque.
