Viega 79700 – Frequently Asked Questions
1) Can I use the 79700 ProPress union to connect a water heater or valve with male threads?
That is exactly what the female pipe thread end is for. The 1/2 inch FPT side threads onto a 1/2 inch male NPT nipple, valve tailpiece, or appliance stub, and the other side presses onto 1/2 inch copper tube. If the equipment connection is female instead, you need a male adapter fitting rather than this union.
2) Do I need a special tool to install the 1/2 inch ProPress union?
Yes. The pressed end is a ProPress socket, so it needs a press tool with the matching 1/2 inch ProPress jaw. Nothing is soldered or glued. The FPT side is made up conventionally with thread sealant or tape. Buy the union as a fitting only; no tool or jaw is included.
3) Is the Viega 79700 union lead free for potable water?
It is a Zero Lead bronze union, which is what you use on potable water lines. The body material is bronze, cast for lead-free service, and it is made in Germany.
4) What does Smart Connect do on this Viega union?
Smart Connect is the feature built into the ProPress socket that lets a small amount of liquid or gas escape past the seal if the joint was never pressed. When you pressure test the system, an unpressed 79700 shows itself instead of hiding until the wall is closed.
5) How much space do I need around the Viega 79700 union in a tight wall or ceiling cavity?
Body dimensions are 1.024 inches long, 1.181 inches high and 1.5 inches wide, and it weighs 0.304 lbs. Plan for clearance beyond that, though: the press jaw needs room to open and close squarely around the socket, so the jaw footprint, not the fitting, usually decides whether a cramped cavity works.
6) Will this bronze ProPress union work on a copper line that already has Viega press fittings on it?
It will. The pressed end is a standard Viega ProPress 1/2 inch socket, so it presses onto the same 1/2 inch copper tube with the same tool and jaw you are already using on that run. The bronze body is intended for potable water service alongside copper press fittings.
7) Is the Viega 79700 the right part number for a 1/2 inch press by 1/2 inch female thread union?
Yes, 79700 is the manufacturer part number for the 1/2 inch x 1/2 inch Viega ProPress union in Zero Lead bronze with a female threaded end. Order by that number when matching an existing Viega ProPress system.
