The ASC Engineered Solutions 300151206 is a black cast iron concentric reducer designed to transition between pipe sizes in threaded piping systems. This fitting reduces a 2.5-inch connection down to a 1.5-inch connection using a concentric design, keeping both pipe centerlines aligned. Weighing 2.75 pounds, it is built from cast iron with a black coating for corrosion resistance in standard service conditions. Licensed plumbers and pipefitters install this fitting in commercial and industrial pipe runs where a straight, centered reduction is required.
This concentric reducer is suited for use in water supply, hydronic heating, and general-purpose piping systems where maintaining pipe alignment is a priority. The concentric geometry is preferred in horizontal runs where flow balance and system symmetry matter. It is domestically produced and intended for threaded pipe assembly in both new construction and retrofit applications.
Designed as an OEM-style replacement or new-installation fitting for threaded cast iron piping systems requiring a concentric reduction from 2.5-inch to 1.5-inch pipe.
This fitting is installed by licensed plumbers or pipefitters working on threaded piping systems. Shut off and depressurize the system fully before removing or installing any threaded fittings. Apply appropriate thread sealant or PTFE tape to all male threads before assembly, following local plumbing code requirements such as the IPC or applicable mechanical codes. Do not over-torque threaded cast iron fittings, as the material is brittle and may crack under excessive force.
