Viega 84815 – Frequently Asked Questions
1) Can I use the Viega 84815 MegaPress union on copper or PEX?
No. The 84815 is a carbon steel press fitting, made for black iron / carbon steel pipe systems. For copper you need a copper press fitting (ProPress) and for PEX a PEX fitting. Putting a carbon steel MegaPress body on copper tube is the wrong material and the wrong sealing element.
2) Why choose a press union instead of a threaded union on black iron pipe?
A press union like the 84815 is made up with a press tool in seconds, with no threading, no cutting oil and no flame, which is what gets it used in occupied buildings and retrofit work where hot work permits are a problem. A threaded union still makes sense when you need to break the joint repeatedly for service, or when no press tool and jaws are on site, since a press joint is permanent once crimped.
3) Does the Viega 84815 have the Smart Connect feature, and what does it do for the installer?
Yes, the 84815 MegaPress union is a Smart Connect fitting. The feature lets an unpressed connection leak visibly during pressure testing, so a joint you missed shows itself at test rather than after the wall is closed. It does not replace pressing, it just makes the skipped one findable.
4) What is the weight and origin of the Viega MegaPress 84815 union for submittal paperwork?
Each 84815 union weighs 0.771 lbs and is made in Germany. The body material listed is carbon steel.
5) Is Viega 84815 the part number I give my supplier?
Yes. 84815 is the Viega manufacturer part number for the 1/2 inch x 1/2 inch MegaPress carbon steel union. Order by that number and the size, since MegaPress fittings run across many sizes and body styles under similar descriptions.
