Potable Water Copper Tee

The NIBCO U611 is a sweat-fitting tee made from wrought copper for potable water systems. All three branches accept 1/4 inch nominal copper tube with a 3/8 inch outer diameter. Each connection uses a cup joint for soldered installation. The fitting joins three equal copper lines in a single junction.

Plumbing Installers And DIY Repairers

This tee suits plumbers and homeowners extending or branching copper supply lines in residential or light commercial projects. It is not intended for drainage, gas, or high-pressure hydraulic circuits that require different fitting classes or materials. Builders needing threaded, push-fit, or compression connections should select alternative fitting styles.

Wrought Copper Sweat Tee

The defining specification is the all-cup, equal-run tee configuration in wrought copper for potable water. This exact combination of material, joint type, and branch sizing determines compatibility with existing copper tube and soldering workflow. Verify that the system design calls for a 1/4 inch nominal sweat tee before purchasing.

Questions about this item

Should I choose the U611 tee or a different size for my 1/4 inch nominal copper tubing?

The U611 is made for 1/4 inch nominal copper tube, which has a 3/8 inch outside diameter. All three ends are cup connections sized for that tube.

What does the 1/4 inch nominal size mean when I sweat this tee into my water lines?

It means each port accepts 1/4 inch nominal copper tube with a 3/8 inch outer diameter, giving a uniform tee joint for potable water systems.

How does the sweat cup connection limit the pressure or temperature I can run?

The wrot copper tee uses sweat cup joints on all three ends, so the practical limits come from the solder you use and the copper tube rating, not the fitting itself.
