Copper Reducing Tee for Drain Systems

The Nibco 611R is a wrot copper reducing tee designed for drain component installations. It connects three tube ends using C x C x C solder joints in a 2-1/2 in by 2-1/2 in by 1-1/4 in nominal configuration. The fitting meets ASME/ANSI B16.22 standards for copper tube fittings.

Pressure and Temperature Performance

Under sustained operating conditions the tee handles a maximum pressure of 336 psi at 100 degrees Fahrenheit. Its rated temperature range extends from -20 degrees to 400 degrees Fahrenheit, allowing continuous service in both chilled and high-temperature drain lines without degradation.

Installation Verification Points

Before ordering confirm that your piping uses 2-5/8 in outside diameter on the two main runs and 1-3/8 in on the branch. Ensure the system design specifies copper-to-copper solder connections and that the working pressure and temperature stay within the rated limits.

Questions about this item

Does the copper tee add any noise or heat when water runs through it all day?

The wrot copper body is passive, so it adds no noise or heat during continuous flow.

What pipe and tools must I already have to install this 2-1/2 x 2-1/2 x 1-1/4 in C x C x C reducing tee?

You need matching 2-5/8 in and 1-3/8 in outside-diameter copper tube, flux, lead-free solder and a torch for sweat joints.

Will this ASME/ANSI B 16.22 tee work with older copper pipe already in the system?

Yes, it meets ASME/ANSI B 16.22 and fits standard copper tube sizes, so it joins existing copper without adapters.
