Viega 77717 – Frequently Asked Questions
1) What size copper tube does the Viega 77717 ProPress cap fit?
The 77717 is a 3/4 inch ProPress cap, so it presses onto 3/4 inch copper tube. It is a copper fitting with a press connection on the single end, meaning it terminates a run rather than joining two pieces. For any other tube size you need the matching size in the ProPress cap range, not this part.
2) Do I need to solder the Viega 77717 cap, or is it a press fitting?
No soldering. The 77717 is a press-connect cap (connection type P), so it is installed cold with a ProPress tool and the correct 3/4 inch jaw. That is the reason contractors use it to cap a line in an occupied building or near combustibles, where a torch is a problem.
3) Can I use a ProPress copper cap on PEX or steel pipe?
No. The 77717 is a copper press fitting sized for 3/4 inch copper tube. PEX needs a PEX press system, and steel or galvanized pipe needs a threaded or ProPress-for-steel fitting. Match the fitting family to the pipe material, not just the size.
4) What does Smart Connect technology do on this Viega ProPress cap?
Smart Connect is the small feature in the sealing element that lets an unpressed 77717 cap leak a little when the system is tested, so an installer can spot a connection that was missed before the wall closes up. It does not change how the fitting is pressed or the 3/4 inch copper size.
5) How much space does the Viega 77717 cap take up on the end of the tube?
It is a compact fitting: 1.067 inches long and 1.248 inches across, weighing 0.088 lbs. That length matters when you are capping a stub in a tight joist bay or behind a fixture, because you need enough straight tube plus jaw clearance to make the press.
6) Is a press cap suitable for permanently abandoning a branch line, or should I use a valve?
A 77717 cap permanently closes the end of a 3/4 inch copper branch. Once pressed it is not removable, so use it where the branch is being retired or where a stub is being dead-ended. If you want the branch available again later, install a valve or a threaded adapter with a plug instead.
