Viega 84840 – Frequently Asked Questions
1) What size pipe does the Viega MegaPress 84840 union fit?
The MegaPress 84840 union is a 2 inch by 2 inch fitting, press on both ends. It is built for 2 inch carbon steel pipe, so both sides press directly onto the pipe with no threading or welding.
2) Is the Viega 84840 threaded on either end, or press on both sides?
Both ends are press. The connection is listed as P1 x P2, meaning press by press, so you set it with a MegaPress jaw on each side rather than cutting threads. If you need a threaded transition into a valve or equipment, you want a press by FPT or MPT adapter instead of this union.
3) Can I use the MegaPress 84840 on copper or PEX?
No. This union is carbon steel and made for black iron / carbon steel pipe systems. Copper and PEX need their own press systems, not MegaPress carbon steel fittings.
4) What does Smart Connect do on this Viega union?
Smart Connect is the feature that makes an unpressed connection leak during pressure testing, so an installer can find any joint that was missed before the system goes into service. It is a commissioning safeguard, not a sealing element on its own.
5) Why use a press union instead of a threaded union on 2 inch steel pipe?
A press union lets you make the joint cold, in place, without a pipe threader or a torch, which matters in occupied buildings and hot-work-restricted areas. A threaded union still makes sense when you are tying into existing threaded pipe or need to break the joint for service repeatedly. The 84840 is 2 inch press by press, so it belongs in a run being built or repaired with MegaPress fittings.
