Viega 84550 – Frequently Asked Questions
1) Is the Viega 84550 MegaPress tee a press-by-press-by-press fitting, or does one outlet have threads?
Two of the three ends are press connections and the third is a female pipe thread: the connection type is P1 x P2 x FPT. So the run presses onto 3/4 inch carbon steel pipe at both ends, and the branch takes a male-threaded nipple, valve, or gauge adapter. If you need all three outlets pressed, this is the wrong configuration for you.
2) What pipe size does the Viega 84550 MegaPress tee fit?
It is a 3/4 inch x 3/4 inch x 3/4 inch tee, so both press ends go on 3/4 inch carbon steel pipe and the threaded branch is 3/4 inch FPT. Mixed-size branches need a reducing tee instead.
3) Is the Viega 84550 tee suitable for potable water lines?
It is a carbon steel fitting, which is the MegaPress line used for black iron pipe systems, gas, hydronic heating, compressed air and similar closed or non-potable service. Potable water runs call for copper or stainless press fittings, not carbon steel, because the steel will corrode in open potable service.
4) Can I use a MegaPress carbon steel tee on black iron pipe instead of threading or welding?
That is what it is for. The 84550 is a carbon steel press fitting, so it joins black iron pipe with a press tool rather than cutting threads or welding, which keeps a hot work permit and a pipe threader off the job. The threaded branch lets you keep a conventional screwed connection where you need to land a valve or drop.
5) How much clearance do I need to fit a 3/4 inch MegaPress tee in a tight chase?
The fitting measures 4.528 inches long, 2.331 inches wide and 1.496 inches high, and weighs 0.655 lbs. Allow beyond that for the press jaw to rotate fully around the pipe, which is usually what limits you in a chase or against a joist, not the fitting body itself.
6) What does Smart Connect do on a Viega MegaPress fitting, and does it change how I pressure test?
Smart Connect is a feature of the Viega MegaPress sealing element that leaves an unpressed fitting detectable during pressure testing, so a joint someone missed shows itself instead of leaking after the walls close. It does not replace the press, every joint still has to be pressed with the correct 3/4 inch jaw.
