611 Copper Tee for 3/16 in Tube

This NIBCO 611 tee fitting joins three lengths of 3/16 in copper tube using sweat cup connections on every port. The wrought copper body is intended for potable water systems where a secure, leak-free branch is required. Each end accepts a 5/16 in outside-diameter tube for a standard solder joint.

Suits potable water branch lines.

Plumbers running copper distribution lines for drinking water will find this tee matches the tube size and connection method specified for that service. Installers working with gas, compressed air, hydronic heating or larger-diameter tube should select a fitting rated for those conditions instead.

Sweat cup on all three ports decides fit

The single specification that determines compatibility is the sweat cup connection on sides A, B and C, each sized for 3/16 in copper tube with a 5/16 in outer diameter. If the pipe or project calls for a different joint type or tube size, this fitting will not assemble correctly.

Questions about this item

What size copper tube must I already have to sweat this 3/16 in tee into place?

You need 3/16 in copper tube on all three branches; the cup ends accept 5/16 in outer diameter tube for a standard sweat joint.

Can I mix this wrot copper tee with existing copper pipe without causing galvanic corrosion?

Yes, wrot copper is the same alloy family as standard copper pipe, so no galvanic couple forms when you sweat them together.

How do I confirm the joint is sound after soldering the three connections?

Pressurise the line with water or air and watch for leaks at each cup; a dry joint with no weeping shows the tee is working as intended.
