Product identity

The Nibco C611 is a wrot copper reducing tee designed for plumbing drain systems. It connects two 1-1/4 inch tubes and one 1/2 inch tube using copper-to-copper sweat connections. The fitting meets ASME/ANSI B16.22 standards for material and dimensions. It is supplied new for professional or residential installation.

Suitable applications

This tee suits installers joining dissimilar tube sizes in water supply or heating lines rated up to 439 psi at 100 degrees Fahrenheit. It handles continuous operating temperatures from -20 to 400 degrees Fahrenheit. Builders needing press-fit, push-fit or threaded connections should select a different fitting type. Systems requiring larger or smaller branch sizes will not match this configuration.

Included components

The package contains the single copper reducing tee fitting only. No flux, solder, pipe hangers or sealing compounds are bundled. The installer must supply compatible solder alloy and flux rated for the temperature range. No additional tools or adapters are included for alternative connection methods.

Questions about this item

What copper pipe sizes must I already have to connect this 1.25 x 1.25 x 1/2 in reducing tee?

You need two lengths of 1-1/4 in. copper tube for the run connections and one 1/2 in. tube for the branch, all cut to fit the C x C x C solder cups.

Will the 439 psi rating at 100 °F hold if I keep older copper lines rated to a lower pressure?

The system pressure is limited by the lowest-rated component, so older lines with a lower maximum pressure will dictate the safe working limit.

How can I verify the joint is sound after soldering the C x C x C connections?

Pressurise the line with water or air and inspect every soldered cup for leaks; a tight joint shows no seepage at the 1-3/8 in. and 5/8 in. outside diameters.
