Copper Reducing Tee, Sweat Fitting

This Nibco 611RR copper reducing tee joins three sweat connections in a T configuration. The run measures 1/4 inch nominal tube size on both ends while the branch reduces to 1/8 inch nominal. Wrot copper construction suits potable water systems.

Installers needing a 1/4-to-1/8-inch reduction

Plumbers and HVAC technicians making a sweat joint with this exact size transition will find the part fits directly. Projects requiring a different nominal size combination, a threaded connection, or a non-reducing tee cannot use this fitting.

Reducing tee with 1/4, 1/8, 1/4 nominal sizes

The defining specification is the nominal tube size sequence: 1/4 inch on the run ends and 1/8 inch on the branch. Matching these three dimensions to the piping plan confirms the correct component.

Questions about this item

What copper tube sizes does the 611RR reducing tee connect?

The 611RR reducing tee connects 1/4 in copper tube on side A, 1/8 in on side B, and 1/4 in on side C.

What are the tube outer diameters for each port on this fitting?

Side A and side C have a 3/8 in outer diameter; side B has a 1/4 in outer diameter.

How is this copper tee installed and what common step is missed?

It is a sweat fitting, so clean the tube ends and fitting cups, apply flux, assemble, then heat evenly and feed solder until the joint is full; the step often missed is heating the fitting cup, not just the tube.
