Viega 84820 – Frequently Asked Questions
1) Can I use the Viega 84820 MegaPress union on copper or PEX?
No. The 84820 is a carbon steel MegaPress fitting, made for carbon steel pipe such as black iron. Copper tube needs a ProPress copper fitting and PEX needs a PureFlow fitting, both different product lines with different press jaws.
2) Do I need a special tool to install the Viega 84820 MegaPress union?
Yes. Press fittings like the 84820 are made with a press tool and MegaPress jaws sized for 3/4 inch carbon steel pipe. No thread cutting, no dope, no welding, but the fitting will not work with a wrench alone.
3) What is Smart Connect on the Viega MegaPress 84820 union and why does it matter on an inspection?
Smart Connect is a feature of the press sealing element that lets an unpressed connection leak a small amount during pressure testing, so a joint you missed shows itself before the system goes into service. On a large black iron gas or hydronic job it is the fastest way to catch a skipped press.
4) What part number do I order for a 3/4 inch MegaPress carbon steel union?
Order Viega part number 84820. It is the 3/4 inch by 3/4 inch carbon steel MegaPress union with press ends on both sides.
