Viega 20848 – Frequently Asked Questions
1) What size copper tube does the Viega 20848 ProPress cap fit?
The 20848 is the 4 inch ProPress cap, so it presses onto 4 inch copper tube. It is a copper fitting with a press connection, not solder or thread, so the tube end needs to be cut square, deburred and fully inserted to the stop before pressing.
2) Can I use a ProPress cap to permanently terminate a 4 inch copper line, or is it only for testing?
The Viega 20848 is a permanent copper press cap. Once the 4 inch tube end is pressed, the joint is made and the cap is not removable without cutting it off. If you want a stub-out you can reopen later, use a valve or a threaded adapter with a plug instead of a press cap.
3) What does Smart Connect mean on this Viega cap?
Smart Connect is the feature built into the fitting's sealing element that lets water pass at an unpressed connection during pressure testing, so an unpressed 4 inch cap shows itself before the system is closed up. It is a leak-detection aid on the fitting, not a separate part you order.
4) Will a copper ProPress cap work on stainless or PEX lines?
No. The 20848 is a copper fitting made for copper tube systems. Stainless press systems and PEX systems use their own fitting lines and sealing elements, so the copper cap is not a substitute on either.
5) Is the Viega 20848 made in the USA?
No, the 20848 ProPress cap is made in Germany. Useful to know up front if the job carries a domestic-sourcing requirement.
