Viega 84425 – Frequently Asked Questions
1) What pipe sizes does the Viega MegaPress 84425 reducing tee connect?
The 84425 MegaPress tee runs 1-1/2 inch on both ends of the run with a 1/2 inch branch outlet, so it's a reducing tee for tapping a small branch off a 1-1/2 inch main. All three ends are press connections (P1 x P2 x P3), no threads and no welding.
2) Can I use a MegaPress carbon steel tee on black iron pipe without cutting threads or welding?
That's what it's for. The 84425 is a carbon steel press tee, so it goes on cut-and-cleaned black iron or carbon steel pipe with a press tool instead of threading or welding. No hot work, which is why it gets used in occupied buildings and retrofits where a torch permit is a problem.
3) Do I need a separate reducer to take a 1/2 inch branch off a 1-1/2 inch steel main?
No. The 84425 reduces inside the fitting, 1-1/2 x 1-1/2 x 1/2, so the 1/2 inch branch presses straight into the tee. Using a full-size 1-1/2 inch tee plus a bushing or reducing coupling adds two more joints and more length in the bay.
4) Is the Viega 84425 tee suitable for potable water, or gas and hydronic lines?
Carbon steel MegaPress fittings are the black-iron side of the Viega press line, used on steel pipe systems such as hydronic heating, compressed air, and fuel gas service where the seal is rated for it. Carbon steel is not used for potable water distribution, for that you want copper or stainless press fittings instead of this tee.
5) What does Smart Connect technology on the MegaPress tee actually do for me on the job?
Smart Connect is a feature of the sealing element that intentionally leaks a small amount at an unpressed connection during pressure testing. On a tee like the 84425 you are making three separate presses, so it's the check that tells you none of the three got missed before the system is charged and closed in.
6) What part number should I specify for a 1-1/2 x 1-1/2 x 1/2 MegaPress carbon steel tee?
Viega part number 84425. That is the full identity of the fitting, the carbon steel MegaPress reducing tee with Smart Connect, sized 1-1/2 x 1-1/2 x 1/2 inch.
7) Is the Viega 84425 MegaPress tee made in Germany?
Yes, the 84425 carbon steel MegaPress tee is manufactured in Germany. Useful if your submittal package or procurement spec asks for country of origin on each fitting line item.
