Authentic Asc Engineered Solutions 308004407 Companion Flange 10in

The ASC Engineered Solutions 308004407 is a Class 125 cast iron companion flange designed for use in piping systems requiring a secure, bolted connection between flanged components. Rated at 125 pounds pressure class and finished in a black coating, this flange features a 10-inch nominal fitting size with a 16-inch outer diameter. Weighing 35.75 pounds, it is built for durability in demanding industrial and commercial piping installations. Licensed plumbers and pipefitters install this type of flange where rigid, leak-resistant pipe joins are required. Domestically manufactured, it conforms to standard dimensional requirements for Class 125 cast iron flanges.

This companion flange is suited for commercial and industrial piping systems where cast iron flanged connections are specified. Typical applications include water distribution, low-pressure steam, and process piping where Class 125 pressure ratings are appropriate. It is commonly installed in mechanical rooms, utility plants, and large-scale plumbing systems. The 10-inch nominal size makes it appropriate for main distribution runs where high flow capacity is needed. Installation is typically handled by journeyman plumbers or pipefitters working to ASME or local mechanical code requirements.

Key Features

• Class 125 pressure rating for standard-duty piping applications
• 10-inch nominal fitting size with 16-inch outer diameter for proper mating with standard flanged pipe
• Cast iron construction provides long service life in commercial and industrial environments
• Black coating finish for corrosion resistance and clean appearance
• Domestically manufactured to standard Class 125 dimensional tolerances
• Companion flange type designed for bolted, face-to-face pipe connections

Compatibility

Designed as an OEM-style replacement or new-installation companion flange for Class 125 cast iron flanged piping systems with a 10-inch nominal pipe size.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter. Isolate the line and depressurize the system fully before removing any existing flange or beginning installation. Proper gasket selection and bolt torque sequencing are critical for a leak-free seal — follow applicable ASME B16.1 guidelines and local mechanical codes. Do not overtighten bolts unevenly, as this can distort the flange face and compromise the seal.
