Viega 79705 – Frequently Asked Questions
1) What are the two ends on the Viega 79705 ProPress union, press or threaded?
The 79705 is a transition union: one end is a 3/4 inch ProPress crimp socket, the other is 3/4 inch female pipe thread (FPT). So it presses onto 3/4 inch copper tube on one side and threads onto a 3/4 inch male NPT nipple, valve tailpiece, or appliance connection on the other. If you need press on both ends, this is not the part.
2) Can I use the Viega 79705 union on potable drinking water lines?
Yes. The 79705 union body is zero lead bronze, which is what potable water service calls for, and it is a Viega ProPress fitting intended for plumbing use. The press end joins 3/4 inch copper tube; the FPT end picks up a threaded 3/4 inch connection.
3) What does Smart Connect mean on a Viega ProPress fitting, and why does it matter during pressure test?
Smart Connect is a deliberate feature in the sealing element that lets a small amount of water or air escape from an unpressed 79705 joint during testing, so an installer can find the fitting they missed before the wall closes up. It does not change how the joint is made: you still press the 3/4 inch socket with the matching ProPress jaw.
4) What part number and brand should I put on the PO for a 3/4 inch ProPress bronze union with FPT?
Order Viega part number 79705. It is the 3/4 inch x 3/4 inch zero lead bronze ProPress union with a press socket and a female pipe thread, made in Germany.
