Anvil 1/2" Malleable Floor Flange Trap

The Anvil 0310105002 is a raised floor flange designed for plumbing drain connections. It suits installers joining a 1/2 inch nominal pipe to a flanged fitting in non-pressure systems. The malleable iron body provides structural rigidity for floor-mounted trap assemblies.

Flanged x FNPT Connection With Four Bolt Holes

This flange features a flanged face with four bolt holes mating to a female National Pipe Thread end. The configuration determines whether the part aligns with the existing pipework and mounting pattern. Verify the bolt-circle layout and thread type before purchase.

Plain Malleable Iron Class 150 For Non-Pressure

The plain finish malleable iron meets A197 Class 150 standards and is rated for non-pressure service only. It requires a compatible gasket and bolts to seal the flanged joint. The component does not accept pressurised media, so it must be used in gravity-flow drain installations.

Questions about this item

How does the 1/2" nominal pipe size translate when the flange is installed in a real piping system?

The 1/2" nominal pipe size indicates the flange connects to standard 1/2" pipe via its FNPT threaded end, while the flanged face with four bolt holes mates to a matching Class 150 companion flange or equipment connection.

What does the Class 150 rating actually cap in everyday service?

The product is explicitly marked not for pressure service, so the Class 150 designation reflects dimensional standards for bolt pattern and flange thickness rather than a pressure limit for this fitting.

What physical clearances and hardware are needed to mount this floor flange?

The flange measures 3 1/2 inches in outside diameter with four bolt holes, requiring a matching bolt circle and four bolts to secure it to the floor or mating surface.
