Copper Sweat Tee for Potable Water

This NIBCO 611 tee joins three 5/16 inch copper tubes in a branch layout. It is made from wrot copper and rated for potable water systems. Plumbers and maintenance crews use it to create a perpendicular outlet on a straight run.

Verify tube size and joint method before ordering

Each port accepts 5/16 inch copper tube with a 7/16 inch outer diameter. The connections are cup style for sweat soldering only. Confirm your existing tubing matches these dimensions and that your installation uses soldered joints.

Wrot copper body resists corrosion in water service

The material withstands typical potable water chemistry without degrading. Three identical cup ends allow a uniform soldering technique at every port. No threaded or press adapters are included, so the installer supplies flux, solder and heat.

Questions about this item

Does the Nibco 611 tee come with flux or solder, or must I buy them separately?

The fitting is supplied alone; flux, solder and any cleaning abrasive are purchased separately.

How do I confirm this 5/16 in tee matches the copper tube I already have?

Measure the tube outside diameter — it must be 7/16 in for all three connections to fit this tee.

What does the 5/16 in copper tube size mean once the tee is sweated into a potable-water line?

It indicates the nominal tube size each cup accepts; the joint will carry the same pressure rating as the 5/16 in copper tube system.
