Nibco, Inc. 611RR Reducing Tee 1-1/2 x 1-1/4 x 1 in

Copper Reducing Tee for Potable Water

The Nibco 611RR is a sweat fitting tee designed for potable water systems. It joins three copper tubes of different diameters in a single branch. The fitting uses cup connections on all three sides for solder installation. It suits plumbers and builders working on residential or light commercial supply lines.

Flow Behaviour Under Sustained Use

Wrot copper construction provides a smooth internal bore that resists scaling and corrosion over long service periods. The reducing tee maintains consistent flow distribution across the three outlets without deformation. Joint integrity relies on proper soldering technique rather than mechanical compression. The fitting handles continuous pressure cycles typical of domestic water supply.

Thermal and Pressure Performance

Copper material conducts heat rapidly during soldering, allowing quick, reliable joints with standard torch equipment. Once installed, the fitting withstands normal system pressures and temperature variations in hot and cold water lines. No moving parts or seals mean there is no wear or noise generation in service. The fitting is not suited for gas, steam or high-pressure hydraulic applications.
