Viega 78057 – Frequently Asked Questions
1) Does the Viega 78057 ProPress coupling have a stop, and when do I need that instead of a coupling without a stop?
The 78057 is a 1 inch by 1 inch ProPress copper coupling with a stop, meaning there is an internal shoulder that sets insertion depth on both ends. Use it for normal joins where you can bring both tube ends into the fitting. When you have to slip a coupling over a fixed run, or repair a cut line where neither end can move, you need a coupling without a stop so it can slide along the tube before pressing.
2) What size and type of pipe does the Viega 78057 coupling join?
It joins 1 inch to 1 inch, press on both ends (P1 x P2 configuration), and the fitting body is copper, so it is for copper tube pressed with a ProPress tool and jaw sized for 1 inch.
3) What is Smart Connect on this Viega ProPress coupling and why does it matter on a big repipe?
Smart Connect is the feature Viega builds into the sealing element of the 78057 so an unpressed connection leaks visibly during pressure testing rather than passing quietly. On a multi-story repipe with hundreds of joints, that is how you find the one the crew missed before the walls close.
4) Is the Viega 78057 coupling made in the USA for a Buy American job?
Yes. Country of origin on the 78057 ProPress copper coupling is listed as Made in USA, which is what public and institutional specs with domestic-content requirements typically ask you to document.
5) Do I need to buy sealing elements or anything else separately with this ProPress coupling?
No separate seal purchase. The 78057 arrives with its sealing element installed in each press end. What you supply is the press tool with a 1 inch jaw, a clean square-cut tube end deburred and marked to depth, and a pipe support plan. No solder, flux or torch, which is why these get specified in occupied buildings where hot work permits are a problem.
6) What is the exact Viega part number to order for a 1 inch ProPress copper coupling with stop?
Order Viega part 78057. That number covers the 1 inch by 1 inch copper ProPress coupling with stop and Smart Connect.
