Viega 91910 – Frequently Asked Questions
1) What pipe sizes does the Viega MegaPress 91910 tee connect?
The 91910 MegaPress tee is a reducing tee sized 1-1/2 inch x 1-1/2 inch x 1-1/4 inch. The run is 1-1/2 inch on both ends and the branch reduces to 1-1/4 inch, so you can tap a 1-1/4 inch branch off a 1-1/2 inch line without adding a separate bushing.
2) Are all three ends of the Viega 91910 tee press connections?
Yes. All three outlets are press ends, listed as P1 x P2 x P3, so there is no threaded or socket end on this fitting. Every connection is made with a Viega press tool and the matching jaw or ring for the size.
3) Is the Viega MegaPress 91910 tee suitable for corrosive or wet environments?
The body is 316 stainless steel, the grade specified where chloride exposure, washdown, or corrosive service is a concern. That makes it a fit for coastal mechanical rooms, food and beverage plants, and chemical lines where a carbon steel fitting would pit.
4) What does Smart Connect technology do on a Viega MegaPress fitting?
Smart Connect is a deliberate feature in the sealing element that lets an unpressed connection leak when the system is tested. The point is that an inspector or installer finds the missed joint during pressure test rather than after the wall is closed. It does not replace pressing, it flags the joints you forgot.
5) How much room do I need to fit the Viega 91910 MegaPress tee between hangers?
The fitting measures 6.953 inches long, 4.583 inches wide, and 2.437 inches high, and it weighs 1.849 lbs. Plan your clearance around the 6.953 inch run dimension plus the tool jaw swing, since the press tool needs clear access around each of the three ends.
6) Can I use the 91910 MegaPress tee on black iron or carbon steel pipe, or does it need stainless pipe?
MegaPress fittings press onto schedule 10 through schedule 40 steel pipe, and the 316 stainless version is specified when the piping system itself is stainless or when the service fluid and ambient conditions would attack a carbon steel fitting. If you are pressing onto standard black iron gas or hydronic pipe, the standard carbon steel MegaPress tee is the normal choice and the stainless body is an upgrade you pay for without needing it.
7) Do I need a special press jaw for the 1-1/4 inch branch on this tee?
Yes, each size on the tee needs its own tooling. The two 1-1/2 inch run ends and the 1-1/4 inch branch are different press sizes, so you need both the 1-1/4 inch and 1-1/2 inch jaws or press rings on hand before you set this fitting. Showing up with only one size is the usual reason a reducing tee stalls a job.
8) Where is the Viega 91910 MegaPress stainless tee manufactured?
Made in Germany. That matters on public and institutional work where country of origin has to be documented in the submittal package.
9) What is the manufacturer part number for the 1-1/2 x 1-1/2 x 1-1/4 MegaPress stainless tee?
Viega part number 91910. Order by that number to get the 316 stainless 1-1/2 inch x 1-1/2 inch x 1-1/4 inch press tee, since the carbon steel MegaPress tee in the same size carries a different number.
