The ASC ENGINEERED SOLUTIONS 300150703 is a black cast iron concentric reducer fitting designed to transition between a 2-inch pipe and a 1-1/4-inch pipe in threaded piping systems. The concentric design keeps both pipe centerlines aligned, making it the correct choice when maintaining a straight run centerline is required. Weighing 1.78 pounds and finished with a black coating, this fitting is built for industrial and commercial piping applications where durability and a consistent bore alignment matter. It is typically installed by licensed plumbers and pipefitters working on gas, water, or general-purpose piping systems.
This reducer is suited for residential and commercial piping installations where a reduction from 2-inch to 1-1/4-inch pipe is needed within a straight run. Common applications include gas distribution piping, hydronic heating systems, and general-purpose black iron piping assemblies. The black coating is standard for gas service piping and is compatible with typical threaded black iron pipe systems found in mechanical rooms, boiler rooms, and utility spaces.
Designed as an OEM-style replacement or new-installation fitting for threaded black iron pipe systems requiring a concentric reduction from 2 inches to 1-1/4 inches.
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 relevant. Shut off and depressurize the piping system fully before removing or installing any fittings. Use appropriate pipe thread sealant rated for the intended service medium when making threaded connections. Do not over-tighten threaded connections, as cast iron fittings can crack under excessive force.
