Viega 79140 – Frequently Asked Questions
1) What size pipe does the Viega 79140 ProPress union connect?
The Viega 79140 union is a 1-1/4 inch by 1-1/4 inch press fitting, with press ends on both sides (P1 x P2). It joins two runs of 1-1/4 inch copper tube of the same size, no reducing.
2) Does the Viega 79140 union need threading or soldering?
Neither. Both ends are ProPress press connections, so it is made up cold with a press tool and the correct 1-1/4 inch jaw. No flame, no flux, no pipe threading on either side.
3) Is the Viega 79140 union lead free for potable water?
It is a Zero Lead bronze body, which is what Viega designates for potable water service. Bronze is the material on both the union body and ends.
4) What does Smart Connect do on this Viega press union?
Smart Connect is the feature that leaves an unpressed connection deliberately leaking during pressure test, so an installer can find a joint that was missed before the system is closed in. It is built into both press ends of the 79140.
5) Will the Viega 79140 fit in a tight joist bay or chase?
The fitting measures 2.087 inches high, 1.969 inches long and 2.283 inches wide. Allow clearance beyond that for the press tool jaw to swing around the fitting, which is usually the limiting factor rather than the fitting body.
6) Should I use a press union or a threaded union on a 1-1/4 inch copper line?
A press union like the 79140 is the choice when you are joining copper tube directly and want a serviceable break in the line without heat or thread cutting. A threaded union makes sense only where you already have male pipe threads to land on, since the 79140 has press ends on both sides and no threaded port.
7) Where is the Viega 79140 ProPress union made?
It is made in Germany. For public and institutional jobs with domestic sourcing language in the spec, that matters, so check the bid requirement before standardizing on it.
8) What is the Viega part number for the 1-1/4 inch ProPress bronze union?
Order it as Viega 79140. That is the manufacturer part number for the 1-1/4 inch x 1-1/4 inch Zero Lead bronze ProPress union.
