Viega 77737 – Frequently Asked Questions
1) What size pipe does the Viega 77737 ProPress cap fit?
The Viega 77737 is a 2 inch ProPress cap. It presses onto 2 inch copper tube, so it caps off a 2 inch branch or stub without soldering. For any other line size you need the matching ProPress cap in that diameter.
2) Can I use a ProPress cap instead of sweating a copper cap on a live-ish system?
That is the point of it. The 77737 is a press-fit copper cap, no torch, no flux, no solder. You prep and cut the 2 inch tube, mark the insertion depth, slide the cap on and press with the correct 2 inch jaw or ring. On a 2 inch line that matters, since heating a large-diameter copper stub with residual water in it is the usual reason a sweat joint fails.
3) What is Smart Connect on the Viega 77737 cap and why does it matter on a pressure test?
Smart Connect is Viega's unpressed-connection feature: an unpressed fitting leaks deliberately during test so the installer finds it before the walls close. On a capped 2 inch stub that is exactly the joint people forget, since nothing downstream of it announces the problem. Press it, then test.
4) Is the Viega 77737 copper or bronze, and can I put it on a copper potable water line?
It is a copper-bodied ProPress cap, the same base metal as the tube it presses onto, which is what you want on copper potable and hydronic lines to avoid mixing dissimilar metals at the joint. Viega makes this one in Germany.
5) What part number do I order for a 2 inch Viega ProPress copper cap?
Order Viega part 77737. That is the manufacturer number for the 2 inch copper ProPress cap with Smart Connect, and it is the number to give a wholesaler or put on a submittal.
6) Does the 77737 ProPress cap come with the sealing element installed?
ProPress copper fittings ship with the sealing element already seated in the bead, so nothing extra is ordered alongside the cap for a standard water application. What you do supply is the press tool and a 2 inch jaw or ring, plus a deburring tool and depth marker for the tube prep. The cap weighs 0.431 lbs, so it is light enough to hang on a stub while you set the tool.
