The ASC ENGINEERED SOLUTIONS 300156007 is a black cast iron eccentric reducer designed for piping systems that require an offset centerline transition between two different pipe sizes. Sized at 2.5 inches by 1 inch, this fitting connects a larger pipe to a smaller pipe while keeping one flat side aligned, which is critical for drainage applications and systems where air pockets must be avoided. At 2.74 pounds, it is a domestically produced cast iron fitting suitable for use in commercial and industrial piping installations. Licensed plumbers and pipefitters are the typical trade professionals who specify and install this type of reducer.
Eccentric reducers are commonly used in horizontal pipe runs where maintaining a consistent invert elevation is necessary, such as in drain, waste, and vent systems, steam piping, and certain process piping applications. The flat-side orientation of an eccentric reducer prevents air or gas accumulation in liquid lines and keeps drainage flowing properly. This fitting is appropriate for both new construction and retrofit piping work in commercial buildings, industrial facilities, and multi-family residential projects.
Designed as an OEM-style replacement or new-installation fitting for cast iron pipe systems requiring a 2.5-inch to 1-inch eccentric reducing connection.
Installation of cast iron pipe fittings should be performed by a licensed plumber or pipefitter in accordance with applicable plumbing codes, including the IPC and local amendments. Shut down and depressurize the piping system completely before cutting into any existing line. Use appropriate joint methods for the piping system type, such as threaded, grooved, or mechanical joint connections, as specified by the system design. Verify eccentric reducer orientation before final assembly to ensure the flat side is positioned correctly for the intended drainage or flow direction.
