Hexagonal red brass reducing coupling with threaded ends

Value Brand

Value Brand 2" x 1" FNPT Red Brass Reducing Coupling

SKU CH-VS07-BBKK2

Red brass reducing coupling joins 2-inch and 1-inch FNPT threads, rated 125 psi from -20 to 400 degrees F per ASTM B584 and ASME B16.15

  • Red brass construction resists corrosion for long service life
  • FNPT threaded ends create secure leak-free connections
  • Class 125 rating handles up to 125 psi working pressure
  • Operates reliably from -20 to 400 degrees Fahrenheit
  • Meets ASTM B584 ASME B16.15 ANSI B1.20.1 standards

Plumbing fitting for size transitions

The Value Brand reducing coupling joins a 2 inch pipe to a 1 inch pipe using female National Pipe Thread connections on both ends. It is made from red brass to ASTM B584 and rated for Class 125 service. The component suits residential and light commercial water, air or gas lines that require a step change in diameter.

Standards and pressure envelope

The fitting meets ASME B16.15 and ANSI B1.20.1 for thread form and dimensional tolerances. It handles a maximum working pressure of 125 psi across a temperature span of -20 to 400 degrees Fahrenheit. These ratings define the design envelope for any system that incorporates the coupling.

Thermal and chemical considerations

Red brass construction resists dezincification and handles the full rated temperature range without softening or embrittlement. The joint introduces no moving parts, so it adds no vibration or noise to the pipeline. California Proposition 65 notices apply because the alloy contains listed chemicals.

Questions about this item

What is the maximum operating pressure of this 2" x 1" FNPT red brass reducing coupling?

The coupling is rated for a maximum pressure of 125 psi according to the ASME B 16.15 and ASTM B584 standards listed in the specifications.

How does the temperature range affect the fitting during continuous operation?

The fitting handles a temperature range from -20 to 400 degrees F, so sustained high-temperature service up to 400 degrees F is within its design limits.

Which piping standard must the existing pipe threads match for this coupling to seal correctly?

The FNPT connection follows ANSI B 1.20.1, so the mating pipe threads must conform to that same National Pipe Thread standard.
