Viega 79750 – Frequently Asked Questions
1) Is the Viega 79750 ProPress union press on both ends, or does one side thread?
One end presses, one end threads. The 79750 is a P x MPT union: a 1-1/2 inch ProPress crimp socket on one side and a 1-1/2 inch male pipe thread on the other. So it is the fitting you use where a pressed copper run has to land on a female-threaded connection, like a valve, pump, or equipment tapping, and still be able to break apart later.
2) Will the Viega 79750 press onto 1-1/2 inch copper tube?
Yes, the press end is sized for 1-1/2 inch tube, matching the 1-1/2 inch thread on the other side. Use a press tool with the 1-1/2 inch ProPress jaw or ring and actuator; the fitting itself does not include any tooling.
3) Is the Viega 79750 union lead free for potable water?
The 79750 is a zero lead bronze body, which is what the material is specified as for potable water service. Bronze also means it can sit in a copper system without the dissimilar metal issues you would get from a ferrous fitting.
4) What does Smart Connect do on a Viega ProPress union, and does it mean I can skip pressing a joint?
No, it does not replace pressing. Smart Connect is a feature of the sealing element that lets an unpressed connection leak intentionally during pressure testing, so you find the joint you missed before the system is covered up. Every ProPress socket on the 79750 still has to be pressed.
5) Can I take the Viega 79750 union apart after it is installed?
That is the point of a union. The threaded nut lets you break the connection at this fitting to pull a pump, valve, water heater, or section of pipe without cutting the copper. The pressed side stays permanent; the union body unthreads.
6) How much room do I need to fit the Viega 79750 in a tight chase?
The fitting measures 2.441 inches long, 2.413 inches wide and 2.598 inches high, and weighs 1.654 lbs. Remember the width figure is the nut across the flats, so leave wrench swing on top of that, plus clearance for the press jaw on the copper side.
7) I need to order the Viega 1-1/2 inch press x male thread union by part number, which is it?
Viega part number 79750, a 1-1/2 inch x 1-1/2 inch ProPress bronze union with a male pipe thread outlet. Made in Germany. That one number covers it; there are no finish or option variations to specify.
