Anvil 1" Flanged Floor Trap

The Anvil 0310105408 is a raised-face flange designed for 1-inch nominal pipe size connections. It features a flanged end with four bolt holes mating to an FNPT threaded end. The fitting is cast from malleable iron to ASTM A197 and carries a Class 150 rating. It is supplied in a plain finish and is not rated for pressure service.

Plumbers needing a 1-inch transition piece

This component suits installers joining a flanged pipeline to a female-threaded pipe or fitting at 1-inch nominal size. The malleable iron construction handles standard mechanical and thermal loads in drainage or low-pressure piping. It will not serve systems requiring a pressure-rated joint, a different nominal diameter, or a welded connection instead of a bolted flange.

Straightforward bolt-up installation

Alignment is simple: position the 4-inch diameter flange against the mating face, insert bolts through the four holes, and thread the FNPT end onto the male pipe. Common issues include cross-threading the taper threads, omitting suitable thread sealant, or over-tightening the flange bolts and cracking the iron casting. Ensure the mating flange surface is flat and clean before assembly.

Questions about this item

What size pipe must I already have to connect this 1" FNPT flanged trap?

You need a 1-inch nominal pipe with male NPT threads to mate with the female NPT end of this fitting.

Can I bolt this Class 150 malleable-iron flange to an existing cast-iron drain flange that uses the same four-hole pattern?

Yes, the four bolt holes on the 4-inch outside-diameter flange align with standard Class 150 patterns used on older cast-iron floor flanges.

After installation, how can I confirm the trap is seated and leak-free without pressure-test equipment?

Run water through the drain and watch the joint; no seepage at the flange face or threads means the A197 malleable-iron fitting is sealing correctly.
