Floor Flange for 1-1/4" Pipe

This malleable iron floor flange connects a 1-1/4 inch nominal pipe to a female NPT thread. It suits plumbing installations that require a secure floor-mounted anchor point. The Class 150 rating fits standard low-pressure water, oil or gas lines in residential and light commercial systems.

Temperature Range and Pressure Class

The fitting operates from -20 to 366 degrees Fahrenheit, so it handles both chilled-water returns and hot-water supply without derating. Malleable iron to ASTM A197 maintains strength across that span, and the Class 150 designation confirms the pressure envelope for continuous service rather than brief test spikes.

Malleable Iron Construction and FNPT Connection

The A197 casting resists cracking under mechanical shock better than grey iron, giving durability when the pipe sees vibration or occasional impact. Female NPT threads accept standard male pipe ends without adapters, and the 3/4 inch overall length keeps the assembly close to the floor for a clean, low-profile installation.

Questions about this item

How much heat can the malleable iron flange handle during continuous use?

The flange is rated for service temperatures from -20 °F up to 366 °F, so it will withstand typical hot-water or steam lines without softening.

What pipe thread and fitting standard are needed to connect this flange?

It accepts a 1-1/4 inch nominal pipe with FNPT threads and meets the A197 Class 150 pattern for standard flanged joints.

Will the Class 150 bolt pattern match older malleable iron flanges already in the system?

Yes, the A197 Class 150 drilling is the long-standing industry standard, so it aligns with existing malleable iron flanges of the same class.
