Copper Reducing Tee for Potable Water

This NIBCO wrot-copper reducing tee joins three sweat connections in a potable-water system. The run accepts 2-1/2-inch copper tube on both ends while the branch drops to 3/4-inch tube. Sweat joints on all three ports create permanent, leak-resistant seals when soldered correctly. The fitting suits new installations or repairs in residential and commercial supply lines.

Verify Tube Sizes and Soldering Setup

Confirm that the existing 2-1/2-inch and 3/4-inch copper tubes match the fitting's cup dimensions before ordering. Ensure you have a torch, lead-free solder and flux rated for potable water to complete the sweat connections. Check local plumbing codes for any additional requirements on underground or concealed joints.

Sweat Design Eliminates Extra Fittings

The integral cup ends remove the need for separate couplings or adapters when transitioning between the two tube sizes. A single soldered joint on each port reduces potential leak paths and cuts installation time compared with threaded or compression alternatives. No additional sealing compounds or mechanical fasteners are required.

Questions about this item

What comes in the box and do I need to buy solder or flux separately?

The box contains the 611RR reducing tee with three sweat cup connections; solder, flux and copper tubing are not included and must be purchased separately.

How do I confirm this 21/2X3/4X21/2 tee matches my pipe sizes?

The tee has cup ends for 2-1/2 in copper tube on the run and 3/4 in copper tube on the branch; match those outer diameters to your existing tubing.

What does the 21/2X3/4X21/2 marking mean once the tee is installed?

It identifies the nominal copper tube sizes — 2-1/2 in on each straight run and 3/4 in on the outlet — so you can verify the correct flow path after sweating the joints.
