Viega 84420 – Frequently Asked Questions
1) What pipe sizes does the Viega MegaPress 84420 tee connect?
The 84420 MegaPress tee is a 1 inch x 1 inch x 3/4 inch reducing tee, so the run is 1 inch on both ends and the branch drops to 3/4 inch. All three ends are press connections (P1 x P2 x P3), no threading or welding.
2) Can I use a MegaPress carbon steel tee on black iron gas or hydronic pipe instead of threading it?
That is what MegaPress is for. The 84420 is a carbon steel fitting with press ends on all three ports, made to press onto black iron pipe so you skip cutting threads or welding. You need the matching MegaPress press tool and a 1 inch and 3/4 inch jaw set to make the connections.
3) Do I need a separate reducer to branch down to 3/4 inch off a 1 inch line?
No. The reduction is built into the 84420 tee, which takes 1 inch on the run and 3/4 inch on the branch, so you press the smaller branch directly. Using a full 1 inch tee plus a reducing coupling adds two more press joints and about an extra inch of length you may not have.
4) Can I press a MegaPress carbon steel tee onto copper tubing?
No. The 84420 is a carbon steel fitting sized for iron pipe sizes, not copper tube. For copper you want Viega's ProPress copper press fittings instead; mixing the two systems does not work because the sealing element and the jaw profile are different.
5) What does Smart Connect do on this Viega press tee?
Smart Connect is the feature built into each press end that deliberately leaks a little at an unpressed joint during pressure testing, so an installer can spot a fitting that got missed before the system is buttoned up. On a three-port reducing tee like the 84420, that matters, because it is easy to press the two 1 inch run ends and forget the 3/4 inch branch.
6) Is the Viega 84420 made in the US or imported, and what is the exact part number to order?
Order it as Viega MegaPress 84420. It is manufactured in Germany. The fitting weighs 0.97 lbs, which is worth knowing when you are pricing out a box of them for a large mechanical room build.
