Nibco, Inc. 611RR Copper Reducing Tee 2 x 1-1/2 x 1-1/4 in
Copper reducing tee joins 2 in, 1-1/2 in and 1-1/4 in tubes with sweat connections for potable water systems
- Sweat connection enables secure solder joints on copper tubing
- Reducing tee joins 2 in, 1-1/2 in and 1-1/4 in lines in one fitting
- Wrot copper construction resists corrosion in potable water systems
- Cup ends on all three outlets accept standard copper tube sizes
- Lead-free alloy meets drinking water safety requirements
Copper Reducing Tee 2 x 1-1/2 x 1-1/4 in
This Nibco wrot-copper sweat fitting joins three copper tubes of different diameters in a single tee configuration. It suits potable-water systems where a 2-inch main branches to 1-1/2-inch and 1-1/4-inch lines. Plumbers and maintenance technicians use it for residential and light-commercial distribution work.
Sweat-joint limitations
Each cup end accepts the matching copper tube outer diameter and requires a soldered joint made with flux and lead-free solder. The fitting cannot be used with press, push-fit or threaded connections, and it is not rated for gas, steam or high-pressure hydraulic service. Joint integrity depends on proper tube preparation and heating technique.
Installation notes
Clean tube ends and fitting cups thoroughly before applying flux; any oxidation or debris causes leaks. Heat the assembly evenly so solder flows into all three cups without overheating the copper. Common faults are insufficient heat on the largest cup, excess solder blocking the smaller branches, and disturbing the joint before it solidifies.

Questions about this item
Which reducing tee size should I choose for connecting 2 in, 1-1/2 in and 1-1/4 in copper tubing?
This fitting matches those exact tube sizes — Side A is 2 in CTS, Side B is 1-1/2 in CTS and Side C is 1-1/4 in CTS — so select it when your branch lines match those three diameters.
What does the 2 1/8 in outer diameter on the largest outlet mean when I sweat the joint?
That measurement is the actual tube OD that slides into the 2 in cup; your 2 in copper pipe has a 2 1/8 in outside diameter, so the cup fits directly without an adapter.
How does the sweat-cup connection standard limit the pressure or temperature I can run?
The three cup ends are made for standard soldered copper joints; the practical pressure and temperature limits come from the solder alloy and local plumbing code, not from the fitting itself.
