Viega 20843 – Frequently Asked Questions
1) Will the Viega 20843 ProPress cap fit 3 inch copper tube?
Yes. The 20843 is a 3 inch ProPress cap made of copper, so it presses onto 3 inch nominal copper tube. It is a press-fit connection, not solder or thread.
2) Do I need to solder or thread the Viega 20843 cap, or is it a press fitting?
No torch and no threading. The 20843 is a press-connect cap: slide it onto clean, properly prepared 3 inch copper tube and press it with a press tool and the matching 3 inch jaw or ring. Because it is a flame-free connection, it works in occupied buildings and other areas where hot work is restricted.
3) What is Smart Connect on the Viega 20843 ProPress cap, and why does it matter on a test?
Smart Connect is Viega's unpressed-connection feature. If a connection is left unpressed, it leaks during pressure testing so the installer can find it before the system is put into service. On a capped-off 3 inch run that is the whole point of the cap, it lets you pressure test the branch and know the cap itself was actually pressed.
4) How much room do I need to install a 3 inch ProPress cap in a tight chase?
The 20843 measures 3.681 x 2.362 x 3.681 inches, so plan for roughly that envelope plus clearance for the press jaw to close fully around the fitting. In a tight chase the jaw, not the cap, is usually what decides whether the connection can be made.
5) Is the Viega 20843 cap copper or bronze, and will it work on a copper potable water line?
It is a copper-body fitting, which is the standard match for copper tube systems and avoids mixing dissimilar metals at the joint. Viega manufactures it in Germany.
6) Can I use a ProPress cap to temporarily dead-end a line during a renovation?
Yes, capping a stub with the 20843 closes off a 3 inch copper branch so the rest of the system can be charged and tested. Keep in mind a pressed connection is permanent, removing it means cutting the fitting off and re-prepping the tube, so if you expect to reopen the line frequently a valve is the better choice.
