Copper straight reducing coupling FTG 3 in to Cup 1 1/2 in

Nibco, Inc.

Nibco, Inc. 6002 Straight Reducing Coupling 3 in FTG × 1 1/2 in Cup Copper

SKU CH-ENFK-YQ8ZT

A wrot-copper straight reducing coupling joins 3-inch and 1½-inch copper tubes for air, gases or potable water up to 254 psi at 200 °F

  • Reduces 3 in to 1 1/2 in copper tubing for compact transitions
  • Wrot copper construction resists corrosion in potable water systems
  • Straight reducing coupling simplifies layout with direct sweat connections
  • Rated 254 psi at 200 °F for reliable high-pressure service
  • Withstands 400 °F maximum temperature for demanding hot-water applications

Copper Reducing Coupling

The Nibco 6002 straight reducing coupling joins a 3-inch copper tube to a 1 1/2-inch tube in plumbing and HVAC systems. It handles air, gases and potable water in residential and commercial installations. The wrought copper body is rated for 254 psi at 200 degrees F and up to 400 degrees F.

Sweat Fitting Connections

One end uses a 3-inch FTG connection while the other uses a 1 1/2-inch cup connection for sweat soldering. The straight profile keeps the joint inline without an offset. Installers must clean, flux and solder both ends to form a permanent, leak-free seal.

Temperature and Pressure Limits

The coupling withstands a maximum operating pressure of 254 psi at 200 degrees F and a maximum temperature of 400 degrees F. Systems that exceed either limit risk joint failure. The fitting is not suited for pressures or temperatures beyond these ratings.

Questions about this item

What pressure can the 3 in FTG × 1 1/2 in Cup copper coupling handle at 200 °F?

The fitting is rated for a maximum operating pressure of 254 psi at 200 °F.

What tube diameters must the installer prepare for the FTG and Cup ends?

Side A requires a 3 1/8 in outer diameter tube; Side B requires a 1 5/8 in outer diameter tube.

How is the joint made and what step is often missed?

Clean both tubes, apply flux, slide the coupling on, then heat evenly and feed solder until the joint is full; skipping flux or uneven heat causes leaks.
