Asc Engineered Solutions 309004000 Companion Flange 6in Class 125

Product Description

The ASC Engineered Solutions 309004000 is a Class 125 cast iron companion flange designed for use in piping systems where a bolted, mating-flange connection is required. At 6 inches nominal pipe size with an 11-inch outer diameter, this flange provides a robust mechanical joint for water, wastewater, and general industrial piping applications. The galvanized finish adds corrosion resistance for use in wet or exposed environments. Licensed plumbers and pipefitters working on commercial and municipal piping systems are the primary installers of this fitting.

This companion flange is suited for residential and commercial plumbing, waterworks, and mechanical piping systems that operate at Class 125 pressure ratings. The 6-inch size is commonly used in larger distribution lines, pump connections, and equipment flanged tie-ins where a reliable, full-face or raised-face bolted joint is needed. Domestically manufactured, it meets standard dimensional requirements for Class 125 cast iron flanged fittings.

Compatibility

Designed as an OEM-style replacement or new-installation companion flange for Class 125 cast iron flanged piping systems at 6-inch nominal pipe size.

Installation Notes

Installation is performed by licensed plumbers or pipefitters. Isolate and depressurize the line completely before disassembling any flanged connection. Use appropriate gaskets rated for the service fluid and pressure class, and torque flange bolts in a cross-pattern sequence following applicable IPC or ASME B16.1 guidelines. Inspect the mating flange face for damage or corrosion before assembly.
