Viega 84830 – Frequently Asked Questions
1) What size pipe does the Viega MegaPress 84830 union fit?
The MegaPress 84830 union is sized 1-1/4 inch by 1-1/4 inch, press on both ends, so it joins two runs of 1-1/4 inch carbon steel pipe. It will not adapt between sizes, both ports are the same.
2) Is the Viega 84830 press union threaded or does it need a press tool?
Both ends are press connections (P1 x P2), not threads. You need a press tool with the correct MegaPress jaw or ring for 1-1/4 inch carbon steel. No threading, welding, or grooving on the pipe ends.
3) Will the Viega MegaPress 84830 work on black iron pipe already in the building?
It is a carbon steel press fitting made for black iron / carbon steel pipe, so it presses onto existing schedule pipe of 1-1/4 inch without cutting threads. The pipe end has to be cut square, deburred and clean for the seal to set.
4) How much room do I need to install the 1-1/4 inch MegaPress union?
The fitting itself is 6.48 inches long, 2.992 inches wide and 2.756 inches high, so plan clearance for that plus the jaw of the press tool swinging around the pipe. Tight ceiling and wall cavities are where this catches people out.
5) What does Smart Connect do on a Viega MegaPress fitting?
Smart Connect is Viega's unpressed-connection feature: if a joint gets missed during pressing, it leaks on test so the installer finds it before the system is closed up. On a union like the 84830 that matters, since unions often sit at equipment tie-ins that get pressure tested last.
6) Why use a press union instead of a threaded union on a 1-1/4 inch steel line?
A union gives you a disconnect point at a pump, valve or piece of equipment so the run can be broken for service. The press version does that without cutting threads or getting a pipe wrench into the space, which is the main reason crews pick it on retrofit work in occupied buildings. The tradeoff is you need the press tool and jaw on site.
7) How do I order the right Viega 1-1/4 inch MegaPress union?
Order by Viega part number 84830. That is the 1-1/4 x 1-1/4 carbon steel MegaPress union with Smart Connect. It is manufactured in Germany.
