Asc 309004208 Threaded Flange 8 in Class 125 Galvanized

Product Description

The ASC ENGINEERED SOLUTIONS 309004208 is an 8-inch NPSC Class 125 threaded flat face flange manufactured from galvanized malleable iron. Built to ASME B16.1 standards, this flange provides a flat sealing surface for low-pressure piping systems where bolted pipe connections are required. The galvanized finish resists corrosion in wet or exposed environments. At 26 pounds, it is a substantial fitting suited for commercial and industrial piping installations. Licensed plumbers and pipefitters are the typical installers for this class of flanged connection.

This flange is used in Class 125 threaded piping systems handling water, gas, or compatible process fluids in commercial or light industrial applications. The flat face design is standard for cast iron and malleable iron flange pairings where full-face gaskets are required. The 8-inch pipe size makes it appropriate for main distribution lines, pump connections, and large-diameter branch takeoffs in mechanical rooms and plant piping systems.

Key Features

• ASME B16.1 Class 125 rated for standardized low-pressure piping applications
• Flat face seating surface designed for full-face gasket installations
• NPSC threaded bore for direct connection to threaded pipe without welding
• Galvanized finish provides corrosion resistance in wet and outdoor environments
• Malleable iron construction offers impact resistance and machinability
• 13.50-inch outer diameter with 1.75-inch length through hub for standard bolt-circle fitment

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 8-inch Class 125 threaded malleable iron or cast iron flanged piping systems conforming to ASME B16.1.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical codes including ASME B31 and local plumbing codes. Shut off and fully depressurize the piping system before removing or installing any flanged connection. Use a full-face gasket between mating flat face flanges to prevent flange cracking due to uneven bolt load. Do not over-torque flange bolts on malleable iron fittings, and follow bolt-torque sequences per ASME PCC-1 guidelines.
