Copper Reducing Tee

The Nibco U611 is a copper reducing tee designed for plumbing drainage systems. It connects a 1-inch line to two 3/4-inch branches in a tee configuration. Copper construction provides durability and resistance to high-temperature wear. This fitting is intended for use in drain and trap assemblies.

For copper drain installations

This fitting suits plumbers and installers joining copper pipe of the specified sizes in drain applications. It is not intended for supply lines, gas service or press-fit systems requiring different joining methods. Builders needing other diameter combinations or material types should select alternative fittings.

Fitting only

The product is supplied as the reducing tee fitting itself with no additional components. No solder, flux, tools or sealants are included in the package. Installers must provide compatible copper pipe and joining materials separately. The fitting changes the piping layout by reducing the branch size from the main run.
