  • Malleable iron construction resists cracking under mechanical stress
  • Class 150 rating suits standard low-pressure plumbing installations

Floor Flange for 1-1/2 in Pipe

This malleable iron floor flange fits 1-1/2 inch piping and meets Class 150 specifications. It uses a flanged connection with female NPT threads. The fitting conforms to ASTM A-197 standards for material quality.

Replaces Worn or Corroded Flanges

Install this fitting when an existing floor flange shows thread damage, corrosion, or leakage at the base. The Class 150 rating matches standard low-pressure plumbing requirements. The jump is worth it when the old flange can no longer seal reliably.

Verify Pipe Size and Thread Type

Confirm the system uses 1-1/2 inch pipe with male NPT threads before ordering. This flange is not rated for pressure service or saturated steam. Operating temperature must stay within -20 to 366 degrees Fahrenheit.

Questions about this item

What size pipe does the 1-1/2 in floor flange connect to?

The flange accepts a 1-1/2 in pipe with FNPT threads on the flanged connection.

How is the malleable iron floor flange installed onto the piping system?

Thread the FNPT end onto the male pipe threads and bolt the flange base to the floor or mounting surface.

Will the Class 150 malleable iron flange need replacement due to temperature cycling?

It is rated for -20 to 366 degrees F, so normal hot-water cycles stay within limits and replacement is not scheduled.
