Viega 79145 – Frequently Asked Questions
1) Is the Viega 79145 union press on both ends, or does one side thread?
Both ends are press. The 79145 is a P1 x P2 union, meaning a press socket on each side, so it joins two runs of 1-1/2 inch copper tube with no threading and no solder. If you need a transition to threaded pipe, you want a press x male or press x female adapter instead, not this union.
2) What tube size does the Viega 79145 ProPress union fit?
It presses onto 1-1/2 inch copper tube on both ends, 1-1/2 x 1-1/2. A 1-1/2 inch ProPress jaw or ring and actuator is what you need to make the joint; the smaller jaw sets used for 1/2 through 1-1/4 will not close on it.
3) Is this Viega union lead free for potable water?
The 79145 is zero lead bronze, which is the alloy Viega uses for potable water service. Body material is bronze throughout.
4) What does Smart Connect do on a ProPress union, and does it mean I can skip pressing a joint?
No, you still press every joint. The Smart Connect feature is a deliberate leak path at the sealing element so an unpressed connection weeps during pressure test instead of passing inspection and failing later. It makes a missed press visible, it does not replace the press.
5) Why use a union here instead of just a coupling?
A coupling makes a permanent joint. A union lets you break the line later for service, so it belongs where a pump, valve, water heater, or metered assembly has to come out without cutting pipe. The 79145 gives you that serviceable break with press ends on both sides.
6) Can I press the Viega 79145 onto PEX or steel pipe?
No. The zero lead bronze ProPress union is a copper tube fitting; its press sockets are sized for 1-1/2 inch copper. PEX takes Viega's PureFlow system and steel pipe takes the MegaPress line, both separate fitting families with their own jaws.
7) What part number and manufacturer should I put on the submittal for this 1-1/2 inch press union?
Viega part number 79145, a 1-1/2 x 1-1/2 ProPress bronze union. It is made in Germany.
