Copper straight reducing coupling with 2 in and 3/4 in ends

Nibco, Inc.

Nibco, Inc. 6002 Straight Reducing Coupling Copper 2 in x 3/4 in

SKU CH-EE82-PG92E

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

  • Reduces 2 in tube to 3/4 in in one straight fitting
  • Wrot copper construction handles potable water, air and gases
  • Sweat connections on both ends for permanent leak-tight joints
  • Rated to 291 psi at 200 °F for high-pressure lines
  • Withstands continuous service up to 400 °F

Straight Reducing Copper Coupling

The NIBCO 6002 joins a 2 in copper tube to a 3/4 in tube in potable water, air or gas systems. Its sweat fitting ends accept standard copper pipe for a permanent brazed joint. Plumbers and mechanical contractors use it when a straight reduction is required without changing direction.

Pressure and Temperature Limits

The coupling withstands up to 291 psi at 200 °F and continuous temperatures up to 400 °F. Wrot copper construction resists corrosion and scaling in normal service. No moving parts means silent operation and no additional power draw.

Build Integration

The FTG end on the 2 in side slides over the tube while the cup end on the 3/4 in side receives the tube, so the installer must prepare both pipe ends for sweating. The straight body keeps the run linear, freeing space that an elbow or tee would occupy. No extra adapters are needed when the piping matches the listed tube sizes.

Questions about this item

How do I install the NIBCO 6002 sweat coupling and what step do people often get wrong?

Clean both copper tube ends and the fitting sockets with emery cloth, apply flux, insert tubes fully, then heat the joint evenly with a torch until solder flows into the cup by capillary action; the common error is overheating the 2 in fitting side before the 3/4 in side reaches temperature, which burns the flux and leaves voids.

What maintenance or replacement will the NIBCO 6002 coupling need over time?

The wrot copper body requires no scheduled maintenance; inspect joints periodically for green corrosion or weeping, and replace the coupling only if a leak develops or the system is re-piped, since the material withstands 400 Degrees F continuous exposure.

What limit appears first when the NIBCO 6002 coupling runs under sustained high-temperature water pressure?

The 291 psi maximum operating pressure at 200 Degrees F is the first constraint; exceeding this pressure at elevated temperature risks joint failure before the 400 Degrees F temperature ceiling is reached.
