Viega 77712 – Frequently Asked Questions
1) What size copper pipe does the Viega 77712 ProPress cap fit?
The 77712 is a 1/2 inch ProPress cap, so it presses onto 1/2 inch nominal copper tube. It is a copper fitting, so it is for copper tube only, not steel or PEX.
2) Do I need a press tool to install the Viega 77712 cap, or can it be soldered?
It is a press fitting, not a solder cup. The 77712 goes on with a ProPress jaw and a press tool sized for 1/2 inch copper. No torch, no flux, no solder, and nothing else ships with the cap, so the tool and jaw have to be on the truck already.
3) Can I use the 77712 ProPress cap to cap off a stub-out in a tenant unit or vacant space?
That is the normal use. Cut the 1/2 inch copper branch back, deburr and clean the tube, mark your insertion depth, and press the cap on to dead-end the line permanently. It is a sealed cap, so there is no cleanout or future access through it - if you want to reopen the branch later, leave a valve instead.
4) What is Smart Connect on this Viega ProPress cap and why does it matter on a test?
Smart Connect is the feature Viega builds into the ProPress sealing element so an unpressed connection leaks visibly during pressure testing instead of passing and failing later. On a capped stub or a test header, that is the point of using it: you find the missed press before the wall closes up.
5) How much clearance do I need around a 1/2 inch Viega ProPress cap in a tight chase?
The cap itself is small: 0.917 inch long and 0.957 inch across. The limiting factor in a chase is not the fitting, it is the press jaw - you need room to get the jaw fully around the cap square to the tube. Plan clearance for the tool, not the 0.957 inch body.
6) Can a ProPress cap be removed and reused once it has been pressed?
No. A pressed joint is permanent - the jaw deforms the copper around the sealing element, so the 77712 cannot be backed off and re-pressed. Removal means cutting the tube below the cap and pressing on a new fitting.
7) Is the Viega 77712 cap copper or bronze, and will it cause a dissimilar metal problem?
Copper, both in the body and the press end, so on a copper tube system there is no dissimilar metal junction at the cap. Mixing it directly onto galvanized steel would create one, and it is not a fitting for steel pipe anyway.
