Brass Reducing Coupling 2" x 1-1/4

This brass reducing coupling connects a 2-inch female NPT pipe to a 1-1/4-inch female NPT pipe. It meets ANSI B1.20.1, ASME B16.15 and ASTM B62 standards for Class 125 fittings. The fitting is certified to NSF61 and AB1953 for potable water use. It suits plumbing professionals and maintenance teams needing a durable transition between different pipe sizes.

Check Thread Type And Pressure Rating

Verify that both pipe ends use FNPT threads before ordering. The maximum working pressure is 125 psi, so confirm your system operates within this limit. The temperature range spans -20 to 400 degrees F, making it suitable for hot and cold water lines. Ensure the Class 125 rating matches the specification required by your project or local code.

Brass Construction And Threaded Connections

The brass body resists corrosion and handles the stated temperature extremes without degradation. FNPT threads allow direct assembly onto male NPT pipe nipples or adapters using thread sealant or tape. The reducing design creates a step-down in a single fitting, reducing potential leak paths compared to multiple bushings. Brass construction permits disassembly and reassembly for system modifications.

Questions about this item

Does the 2" x 1-1/4" FNPT brass reducing coupling come with thread sealant or do I need to buy PTFE tape separately?

Only the brass reducing coupling is supplied; thread sealant or PTFE tape must be purchased separately for the FNPT connections.

Which fitting class and standard should I select for a 125 psi water line — Class 125 to ANSI B1.20.1 or a different rating?

This coupling is Class 125 and meets ANSI B1.20.1, ASME B16.15 and ASTM B62, matching a 125 psi requirement.

What does the 125 psi maximum pressure rating mean when the coupling is installed in a hot-water system at 400 °F?

The 125 psi rating is the maximum allowable pressure across the full -20 °F to 400 °F temperature range.
