Red brass floor flange with four bolt holes

Value Brand

Value Brand 1" FNPT Red Brass Flange Class 125 200 psi

SKU CH-5V50-ZPA68

A 1-inch FNPT red brass floor flange rated Class 125 for 200 psi maximum operating pressure from -20 to 400 degrees Fahrenheit

  • Red brass construction resists corrosion in water lines
  • Class 125 rating handles 200 psi working pressure
  • FNPT threads connect directly to 1-inch pipe
  • Operates from -20 to 400 degrees Fahrenheit
  • Four bolt holes simplify secure mounting

Brass Flange for 1" Pipe

This Value Brand floor flange connects to a 1 inch nominal pipe using FNPT threads. The red brass body carries a Class 125 rating and a 200 psi maximum operating pressure. It operates across a temperature range of -20 Degrees to 400 Degrees F. Four bolt holes secure the flange to the mounting surface.

Suits Low-Pressure Brass Piping

Installers working with red brass pipe in water, oil or gas lines up to 200 psi will find this fitting matches the class and thread standard. The four-hole pattern aligns with common Class 125 drilling. Buyers who need a higher pressure class, a different flange facing or a material other than red brass should look at something else. This item is restricted from sale in California.

Class 125 Pressure Rating Decides Fit

The single specification that determines whether this is the right part is the Class 125 rating combined with the 200 psi maximum operating pressure. Match this class exactly to the mating flange and system design pressure. A different class or pressure rating will not seal safely in the same joint.

Questions about this item

What pressure does the Class 125 rating limit this flange to?

The Class 125 rating caps the maximum operating pressure at 200 psi for this red brass floor flange.

What bolt pattern and clearance does the 4-1/4 inch outside diameter need?

The flange has a 4-1/4 inch outside diameter with four bolt holes, so the mounting surface must accommodate that diameter and the bolt circle.

How do you seal the 1 inch FNPT threads without cracking the brass?

Wrap the male threads with PTFE tape or pipe dope, thread the flange on by hand, then tighten one to two turns with a wrench; over-tightening splits the red brass.
