The ASC ENGINEERED SOLUTIONS 308011204 is a 4-inch black cast iron reducing flange rated for 125 lb service. It features a 13.5-inch outer diameter and is designed to connect pipes of differing sizes within low-pressure piping systems. Cast iron construction provides durability in demanding commercial and industrial environments. The black coating offers corrosion resistance and a finished appearance. Licensed plumbers and pipefitters install this flange as part of new construction or retrofit piping assemblies where a reducing connection is required.
This reducing flange suits residential and commercial plumbing, hydronic heating, and industrial process piping applications where a 4-inch pipe must transition to a larger-diameter flange connection. The 125 lb pressure class makes it appropriate for standard low-pressure water, drain, and process lines. Its domestic manufacture supports projects requiring domestically produced components. Pipefitters and licensed plumbers are the primary installers for this type of fitting.
Designed as an OEM-style replacement or new-installation reducing flange for 4-inch, 125 lb class cast iron piping systems.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and ASME B16.1 standards for cast iron flanges. Shut off and depressurize the piping system completely before removing any existing flange or fitting. Inspect mating flange faces and gasket surfaces for damage prior to assembly. Do not exceed the 125 lb pressure class rating for this fitting.
