The ASC Engineered Solutions 308009802 is a Class 125 cast iron reducing flange designed for use in piping systems that require a transition between a 4-inch pipe bore and a 10-inch outer diameter flange face. The black coating provides a standard corrosion-resistant finish suited to indoor mechanical and industrial installations. Weighing 16 pounds, this flange is built for durability under moderate pressure service conditions typical of Class 125 applications. Licensed plumbers and pipefitters install this type of fitting when connecting different pipe sizes within a flanged assembly, particularly in commercial and industrial mechanical rooms.
This reducing flange is appropriate for commercial and industrial piping applications where Class 125 cast iron flanged connections are specified. It is commonly installed in HVAC hydronic systems, process piping, and water distribution lines where a flanged reducing connection is required. The domestic origin indicates domestic manufacturing, which may satisfy project specifications requiring domestically produced components. This fitting is installed by licensed plumbers or pipefitters working on flanged piping assemblies governed by applicable mechanical codes.
Designed as an OEM-style replacement or new-installation fitting for Class 125 cast iron flanged piping systems requiring a 4-inch by 10-inch outer diameter reducing connection.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes. Isolate and depressurize the piping system completely before removing any existing flange or beginning installation. Verify flange face alignment and use appropriate gaskets and fasteners rated for Class 125 service. Inspect the mating flange face for damage or debris before bolting up the connection.
