Copper Reducing Tee 3x3x1

The Nibco 611R is a wrot copper reducing tee designed for sweat connections in plumbing systems. It joins a 3-inch run with a 1-inch branch using C x C x C ends. The fitting meets ASME/ANSI B16.22 standards for copper tube fittings.

Installers needing a 3-to-1 transition

This tee suits copper piping projects that require a reducing branch from a 3-inch main line. It is not for press-fit or threaded systems, and it does not fit applications needing a straight coupling or a different branch size.

Rated for 317 psi at 100°F

The fitting handles pressures up to 317 psi at 100 degrees Fahrenheit and operates from -20 to 400 degrees Fahrenheit. It provides reliable service in hot and cold water distribution within these limits. Exceeding the pressure or temperature range risks joint failure.

Questions about this item

What copper tube sizes must I already have to connect this 3 in x 3 in x 1 in reducing tee?

You need three copper tubes with outside diameters of 3-1/8 in, 3-1/8 in, and 1-1/8 in for the CxCxC sweat connections.

Will this fitting handle the pressure and temperature of my existing copper system rated to ASME/ANSI B 16.22?

Yes, the wrot copper tee is rated to 317 psi at 100 Degrees F and a temperature range of -20 Degrees to 400 Degrees F, matching that standard.

After soldering the joints, how can I confirm the tee is holding pressure correctly?

Pressurise the line to its working pressure up to 317 psi and inspect all three sweat joints for leaks; no weeping means the installation is sound.
