The ASC Engineered Solutions 309003002 is a Class 125 galvanized cast iron companion flange designed for use in pipe joining and connection applications across plumbing, mechanical, and industrial piping systems. With a 2-1/2 inch nominal pipe size and a 7-inch outer diameter, this domestically produced fitting provides a reliable mating surface for flanged pipe assemblies. Licensed plumbers and pipefitters install this type of flange when connecting pipe sections or equipment in low-to-medium pressure piping systems. The galvanized cast iron construction offers corrosion resistance and the durability expected in commercial and industrial service environments.
This companion flange is suited for residential and commercial piping installations where Class 125 flanged connections are specified. It is commonly used in water distribution, HVAC hydronic piping, and general mechanical piping applications. The 2-1/2 inch size fits standard pipe in that nominal diameter, and the 7-inch outer diameter is consistent with Class 125 bolt-circle dimensions. Plumbers and pipefitters working on flanged piping assemblies will find this fitting appropriate for standard gasketed flange connections in both new construction and retrofit projects.
Designed as an OEM-style replacement or standard companion fitting for Class 125 flanged piping systems using 2-1/2 inch nominal pipe.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable plumbing and mechanical codes, including the IPC and ASME B16.1 standards for cast iron flanges. Shut off and depressurize the piping system fully before removing or installing any flanged fitting. Use appropriate gasket material rated for the service fluid and pressure class, and torque flange bolts in a star pattern to ensure even seating. Inspect the mating flange face for damage or debris before assembly.
