Hexagonal red brass reducing coupling with threaded ends

Value Brand

Value Brand 1/2" x 1/4" FNPT Red Brass Reducing Coupling bathware

SKU CH-SV2M-EBWKD

Red brass reducing coupling joins 1/2 in and 1/4 in FNPT threads, rated to 125 psi from -20 to 400 degrees F

  • TypeOther
  • Red brass resists corrosion for long service life
  • FNPT threads seal tight without extra sealant
  • Reduces 1/2 in to 1/4 in for flexible piping
  • Rated 125 psi and 400 °F for demanding systems
  • Meets ANSI B1.20.1, ASME B16.15, ASTM B584 standards

1/2" x 1/4" FNPT Red Brass Coupling

This reducing coupling connects a 1/2 inch FNPT pipe to a 1/4 inch FNPT pipe. It is made from red brass to ANSI B1.20.1 and ASME B16.15 standards. The fitting suits plumbing and hydronic systems requiring a durable, lead-free alloy transition.

Suits installers needing a 1/2 to 1/4 transition

Plumbers and maintenance technicians reducing pipe size in water, air or steam lines will find this Class 125 fitting appropriate. It is not for systems exceeding 125 psi or temperatures above 400 degrees F. Installers needing a different thread type or a larger step-down should look elsewhere.

Maximum pressure 125 psi at 400 degrees F

The coupling is rated for 125 psi across a temperature range of -20 to 400 degrees F. This pressure-temperature limit is the decisive factor for safe operation in the intended application. Verify that your system design stays within these bounds before specifying this part.

Questions about this item

What pipe sizes must I already have to connect this 1/2" x 1/4" FNPT reducing coupling?

You need a 1/2-inch male NPT thread on one pipe and a 1/4-inch male NPT thread on the other to screw into the female ends.

Will this Class 125 red brass fitting handle the same 125 psi pressure as my existing ANSI B1.20.1 threaded pipe?

Yes, the coupling is rated to 125 psi and meets ANSI B1.20.1, so it matches the pressure class of standard Schedule 40 threaded pipe.

How can I verify the joint is sound after threading the coupling onto both pipes?

Pressurise the system up to 125 psi and inspect the threads for leaks; the red brass material and ASME B16.15 compliance ensure a reliable seal when properly tightened.
