Anvil 0308002401 1-1/4" Cast Iron Threaded Flange trap

1-1/4" Cast Iron Threaded Flange

The Anvil 0308002401 is a Class 125 cast iron pipe fitting with a 1-1/4 inch flanged by FNPT connection. It is faced and drilled with four bolt holes on a 4 5/8 inch outside diameter for secure alignment. The component meets ASME B 16.4 and UL FM standards for pressure piping systems. It suits installers needing a durable, code-compliant flange for threaded pipe assemblies.

Upgrading from worn or non-standard flanges

Replace corroded, cracked or mismatched flanges that leak at the bolt circle or thread interface. The jump is worth it when the system operates up to 175 psi at temperatures between -20 and 150 degrees F or handles saturated steam at 125 psi. Its standardised drilling pattern eliminates field rework and ensures gasket sealing on the first make-up.

For commercial and industrial steam or water lines

This flange suits maintenance crews and pipefitters working on Class 125 systems that require ASME B 16.4 compliance. It is not for installations needing a larger bore, a different pressure class, a welded connection or a material other than cast iron. Buyers requiring stainless steel, higher temperature ratings or metric dimensions should look elsewhere.
