Brass flange for residential

This red brass flange connects to 1-1/2 inch FNPT pipe threads and suits water, air or steam lines in homes and smaller commercial buildings. The Class 125 rating and brass construction resist corrosion in typical indoor installations. It is not intended for high-pressure industrial mains or cryogenic service.

Threaded connection limits at 200 psi and 400 °F

The FNPT thread seals directly on the pipe without a gasket face so leak-tightness depends on thread quality and sealant. Maximum operating pressure is 200 psi and temperature range is -20 to 400 °F; exceeding either limit risks joint failure. The four bolt holes align with standard Class 125 drilling but the flange itself has no raised face.

Verify pipe size thread type

Confirm the mating pipe is 1-1/2 inch nominal with female NPT threads and that the system pressure and temperature stay within the stated range. California Proposition 65 notices apply because the brass alloy contains listed chemicals. No gaskets or bolts are included so source matching hardware separately.

Questions about this item

Which size should I choose for a 1-1/2 inch pipe?

This flange matches a 1-1/2 inch nominal pipe size and has a 5 inch outside diameter with four bolt holes for standard Class 125 connections.

What does the 200 psi rating mean when the flange is installed?

The 200 psi maximum operating pressure is the highest internal pressure the brass flange can handle continuously at its rated temperature range.

How does the FNPT thread standard affect the seal?

FNPT provides tapered female threads that create a mechanical seal when mated with a matching male NPT pipe, tightening as it is turned.
