2-Inch Copper Sweat Tee

The Nibco 911 tee joins three 2-inch copper tubes with cup connections on every branch. It is made from wrought copper for potable-water systems and rated for a maximum operating pressure of 5 psi. Plumbers use it to create a perpendicular branch on a main supply line.

Behaviour Under Sustained Pressure

The fitting is rated for continuous service at 5 psi in potable-water installations. Its wrought-copper construction resists corrosion and maintains joint integrity during long-term exposure to treated water. The sweat joints form a permanent metallurgical bond that does not degrade with thermal cycling.

Copper Tube Size Limits

Each branch accepts tubing with a 2-inch nominal size and a 2 1/8-inch outer diameter. The cup depth is fixed for that dimension, so the fitting cannot accommodate larger or smaller tube sizes without an adapter. Installers must match the exact copper tube size on all three connections.

Questions about this item

Does the 911 copper tee add noticeable resistance or heat to a potable-water line running continuously?

The fitting is a passive sweat joint with a 5 psi maximum operating pressure, so it contributes no heat and negligible flow restriction when installed correctly.

What tools and materials must I already have to install this 911 tee on 2 in copper tube?

You need a propane or MAPP torch, lead-free solder, flux, emery cloth and a pipe cutter or hacksaw to prepare and sweat the three 2 1/8 in cup ends.

Will the 911 tee mate with older 2 in copper pipe that has a slightly different wall thickness?

Yes — the cup ends accept standard 2 in copper tube with a 2 1/8 in outer diameter, which matches long-standing plumbing dimensions.
