Viega 84780 – Frequently Asked Questions
1) What are the two connections on the Viega MegaPress 84780 adapter?
One side presses onto 1-1/2 inch carbon steel pipe, the other is a 1/2 inch female pipe thread. Viega lists the connection type as P x FPT, so the press end goes on the black iron line and the threaded branch takes a male NPT nipple, gauge, sensor well, or drain valve.
2) Can I use the Viega 84780 MegaPress fitting on copper or PEX?
No. The 84780 is carbon steel and is made to press on carbon steel (black iron) pipe. Copper lines need a ProPress copper fitting and PEX needs a PureFlow fitting; pressing a carbon steel body onto copper is not a valid connection.
3) How much room do I need around the pipe to press the 1-1/2 inch MegaPress 84780?
Plan the clearance off the fitting body, which measures 3.717 inches long by 2.437 inches wide and 2.437 inches high, plus the swing of the 1-1/2 inch press jaw or ring on the tool. In tight mechanical rooms that jaw swing, not the fitting, is usually what decides whether you can make the joint in place.
4) What does Smart Connect do on this Viega press fitting?
Smart Connect is Viega's feature that lets an unpressed joint weep during pressure testing, so a connection you missed shows itself before the system is put in service. On a run with many branch takeoffs it is how you catch the one fitting that never got the jaw on it.
