Viega 90105 – Frequently Asked Questions
1) Is the Viega 90105 MegaPress tee a press fitting on all three ports?
All three ports on the Viega 90105 tee are press connections, listed as P1 x P2 x P3, each sized 1/2 inch. There is no threaded or sweat end on it, so you press all three outlets with a Viega MegaPress jaw set. Nothing on it is welded or soldered.
2) What pipe does a 1/2 inch MegaPress tee go on, copper or steel?
MegaPress is the black iron / carbon steel pipe system, not the copper system. The 90105 is a 1/2 inch x 1/2 inch x 1/2 inch press tee for 1/2 inch IPS steel pipe. If you are working in copper tube, you want a ProPress fitting instead, and in PEX a Viega PureFlow tee. Size on steel pipe is nominal IPS, so 1/2 inch here means 1/2 inch nominal pipe, not outside diameter.
3) Can I use the Viega 90105 to branch off an existing threaded black iron line?
Yes, but the transition has to happen elsewhere. All three outlets of the 90105 are press ends, so you cut the existing steel pipe and press onto the bare pipe ends rather than threading into it. If you need to land on an existing male or female thread, use a MegaPress press-by-thread adapter at that point and keep the 90105 for the press-to-press branch.
4) Why is the Viega 90105 tee 316 stainless instead of carbon steel?
The 90105 tee body is 316 stainless steel, which is the corrosion-resistant version of the MegaPress tee. Specifying stainless on the fitting matters where the line sees moisture, washdown, coastal air, or a mildly aggressive medium, and it is what engineers call out when a plain carbon steel fitting would rust at the joint. It is made in Germany.
5) What does Smart Connect do on this Viega press tee?
Smart Connect is Viega's feature that lets an unpressed joint leak intentionally during pressure testing, so an installer finds the connection they missed before the system is charged and closed in. It is a jobsite verification aid, not a sealing element, and it is built into all three ports of the 90105 tee.
6) How much space do I need to fit the 1/2 inch MegaPress tee in a tight chase?
The 90105 tee measures 4.157 inches long, 2.669 inches wide, and 1.264 inches high, and weighs 0.432 lbs. Those overall numbers only tell part of the story in a tight chase: you also need clearance around the fitting for the press jaw to close squarely on each of the three ports, which is usually the limiting factor rather than the fitting itself.
7) Is the 90105 a reducing tee or are all the openings the same size?
Straight tee, equal on all three ports: 1/2 inch x 1/2 inch x 1/2 inch. If you need to drop the branch to a smaller size, that is a different MegaPress reducing tee part number, not this one.
8) What part number should I order for a 1/2 inch stainless MegaPress tee?
Order Viega part number 90105. That is the 1/2 inch x 1/2 inch x 1/2 inch MegaPress tee in 316 stainless steel with Smart Connect. Its UPC is 691514901053.
