ProPress Reducing Tee for Potable Water

This bronze reducing tee connects 1-1/4 inch copper tube on both press-fit ends to a 1/2 inch FNPT branch. It is designed for potable water systems using the Viega ProPress press-fit method. The integrated center-stop dimple helps align tubing during assembly. The fitting meets a maximum operating pressure of 200 psi.

Bronze Body with EPDM Seals and Press-Fit Ends

The bronze construction resists corrosion in water supply lines while the factory-installed EPDM O-rings seal each press connection without solder or flux. Press-fit ends on the 1-1/4 inch runs allow fast installation with compatible press tools. The FNPT branch accepts standard 1/2 inch male pipe threads for valves or fixtures. Overall length is 3 11/16 inches.

Press-Fit System Limits

The press-fit connections require a dedicated ProPress tool and jaws; they cannot be joined with standard crimp or push-fit tools. The 200 psi pressure rating applies only when the press is completed correctly on compatible copper tube. The FNPT branch limits the fitting to components with matching 1/2 inch male threads and does not suit press-fit or sweat adapters directly.
