Viega 84400 – Frequently Asked Questions
1) What pipe size does the Viega 84400 MegaPress tee fit?
The Viega 84400 MegaPress tee is an equal tee, 1-1/2 inch on all three outlets. All three ends are press connections (P1 x P2 x P3), so it presses onto 1-1/2 inch carbon steel pipe at the run and the branch with no reducing bushing needed.
2) Is the Viega 84400 tee threaded or does it need a press tool?
It is a press fitting on all three ends, not threaded. The 84400 is installed with a press tool and the correct 1-1/2 inch MegaPress jaw or ring, so no threading, grooving, or welding on the pipe. If your run is threaded steel, you either press onto cut plain-end pipe or transition with a press-by-thread adapter.
3) Will a MegaPress carbon steel tee work on black iron gas or hydronic pipe?
MegaPress fittings are made for black iron / carbon steel pipe, and the 84400 body is carbon steel to match the pipe it presses onto. Matching the fitting material to the pipe avoids the dissimilar-metal problem you get pressing a copper-alloy fitting on steel. Carbon steel is not for potable water lines; keep it on closed-loop hydronic, compressed air, and similar black-pipe systems.
4) What does Smart Connect technology on the Viega 84400 actually do for me?
Smart Connect is Viega's unpressed-connection feature: an unpressed fitting leaks deliberately under test pressure so you find the joint you missed before the system is buttoned up and the ceiling is closed. On a tee like the 84400 that matters because you have three joints to press on one fitting, and a skipped branch press is easy to walk away from.
5) How much clearance do I need to install a 1-1/2 inch MegaPress tee?
Plan the pocket around the fitting envelope: 8.827 inches long, 6.358 inches wide, 4.181 inches high. Add room beyond that for the press tool jaw to seat square on each of the three sockets, which is usually the limiting factor in a tight joist bay or against a wall, not the fitting itself.
6) How do I order the right Viega MegaPress tee, and what is the part number for the 1-1/2 inch?
Order by Viega part number 84400 for the 1-1/2 x 1-1/2 x 1-1/2 inch MegaPress carbon steel tee. One model covers it, so there is no finish, seal, or handing choice to specify. If your branch is smaller than the run, 84400 is the wrong part - you want a reducing MegaPress tee instead.
7) Where is the Viega 84400 MegaPress tee made?
Made in Germany. That is the answer institutional and government buyers usually need for country-of-origin documentation on a submittal package.
