Copper reducing coupling with two cup ends, larger and smaller diameter, smooth metallic finish

Nibco, Inc.

Nibco, Inc. 600R 2" x 3/4" Copper Reducing Coupling

SKU CH-A3WT-ZNM65

Copper reducing coupling joins 2 in and 3/4 in tubes for air, gases or potable water, rated to 291 psi at 200 °F

  • Reduces 2 in tube to 3/4 in for versatile plumbing connections
  • Wrot copper construction resists corrosion in air, gas and potable water systems
  • Sweat cup ends on both sides create strong, leak-tight joints when soldered
  • Rated 291 psi at 200 °F for reliable performance under pressure
  • Withstands temperatures up to 400 °F for demanding hot-water applications

Copper Reducing Coupling for Plumbing Systems

This Nibco sweat fitting joins a 2-inch copper tube to a 3/4-inch copper tube in a straight line. It is designed for air, gases, and potable water supply lines. The wrot copper construction provides a reliable joint for residential and commercial plumbing installations.

Pressure and Temperature Limits

The coupling withstands a maximum operating pressure of 291 psi at 200 degrees Fahrenheit. Its maximum operating temperature reaches 400 degrees Fahrenheit. These ratings define the safe working envelope for the fitting in hot water or compressed air systems. Exceeding either limit risks joint failure or reduced service life.

Connection Sizes Determine Fit

The fitting accepts a 2 1/8-inch outer diameter tube on one end and a 7/8-inch outer diameter tube on the other. Both ends use a cup connection for sweat soldering. If your piping uses different diameters or thread types, this coupling will not create a sealed joint.

Questions about this item

Should I choose the 2" x 3/4" reducing coupling or a straight coupling for my pipe run?

Choose the 2" x 3/4" reducing coupling when joining a 2 1/8 in OD tube to a 7/8 in OD tube. A straight coupling only connects tubes of the same diameter.

What does the 291 psi rating mean once the fitting is installed in my system?

The joint will safely handle up to 291 psi at 200 °F, which is the maximum operating pressure for potable water, air or gas lines at that temperature.

How does the sweat connection cap the pressure and temperature I can run?

The sweat (cup) ends require soldering, and the wrought copper material limits the system to 291 psi at 200 °F and 400 °F maximum temperature.
