Reducing Companion Flange 1-1/2

This cast iron reducing companion flange connects a flanged pipe end to a female NPT thread in drainage systems. It carries a Class 125 rating with a maximum operating pressure of 175 psi. The fitting operates reliably from -20 to 150 degrees Fahrenheit. Four bolt holes secure the 7-inch flange diameter.

Plumbing installers and maintenance teams

Suits professionals joining flanged and threaded components in commercial or residential drain lines. Not suited for installations requiring a straight coupling or a larger nominal pipe size. Buyers needing a different pressure class or material should look elsewhere.

Class 125 pressure rating

The Class 125 designation and 175 psi limit determine whether this flange matches the system design pressure. Verify the rating against your piping specification before purchase. The temperature range of -20 to 150 degrees Fahrenheit also governs suitability for the intended fluid service.

Questions about this item

Should I pick the 1-1/2" flanged or the FNPT threaded end for my pipe run?

This reducing companion flange provides both: a 7-inch Class 125 flanged face with four bolt holes on one side and a 1-1/2-inch FNPT threaded connection on the other, so you join flanged and threaded pipe in a single fitting.

What does the 175 psi rating mean once the trap is installed in a real system?

It is the maximum operating pressure the cast-iron body is designed to contain at temperatures between -20 °F and 150 °F; system pressure must stay at or below this value.

How does the Class 125 flange standard limit what I can bolt to it?

Class 125 defines the bolt-circle diameter, hole spacing and flange thickness; only mating flanges or equipment drilled to the same Class 125 pattern will seal correctly with the four bolt holes.
