Viega 91820 – Frequently Asked Questions
1) What size pipe does the Viega MegaPress 91820 cap fit?
The 91820 cap is a 3/4 inch MegaPress fitting, so it presses onto 3/4 inch pipe. It is a press-on cap, not a threaded one, so the pipe end needs to be cut square, deburred and marked to depth before pressing. Overall it measures 2.323 inches long by 1.535 by 1.535 inches.
2) Is the Viega 91820 cap stainless or carbon steel?
316 stainless steel, body and all. That is the grade Viega uses for its stainless MegaPress line, and it is the one specified where carbon steel would corrode, such as chilled water, wash-down areas and corrosive process piping. The fitting is made in Germany.
3) Can I use a 316 stainless MegaPress cap on carbon steel pipe?
Match the metal. The 91820 is a 316 stainless fitting and belongs on stainless pipe; putting a stainless press fitting on carbon steel pipe sets up a dissimilar-metal joint at the connection. For black or galvanized carbon steel pipe, use the carbon steel MegaPress cap in the same 3/4 inch size.
4) What does Smart Connect mean on a Viega MegaPress cap?
Smart Connect is Viega's unpressed-connection feature: an unpressed 91820 cap will leak during pressure test so the installer finds it before the system is charged. It does not change how the cap is pressed, only how a missed press shows itself.
5) Do I need a special press tool jaw for a 3/4 inch MegaPress fitting?
Yes, MegaPress is pressed with a Viega-approved press tool and the MegaPress jaw or ring sized for the pipe, in this case 3/4 inch. The cap itself ships as a single fitting with the sealing element in place; no solder, flux, threading or dope is involved.
6) What is a MegaPress cap used for on a job?
A cap closes off the open end of a run: capping a stub-out, dead-ending a branch left for future tie-in, or sealing a line for pressure test. The Viega 91820 does that on 3/4 inch stainless pipe without hot work, which is why it gets used in occupied buildings where a torch permit is a problem. It weighs 0.227 lbs.
7) What is the Viega part number and UPC for the 3/4 inch stainless MegaPress cap?
Order it as Viega MegaPress model 91820. The UPC on the packaging is 691514918204. It is sold as the 3/4 inch 316 stainless cap.
