Viega 25935 – Frequently Asked Questions
1) What pipe sizes does the Viega MegaPress 25935 reducing tee connect?
The MegaPress 25935 is a reducing tee sized 1 inch x 1/2 inch, so the run takes 1 inch pipe and the reduced outlet takes 1/2 inch. Both ends are press connections, model 25935.
2) Can I use the MegaPress 25935 tee on copper or PEX, or is it only for steel pipe?
It is a carbon steel MegaPress fitting, which is the MegaPress line for black iron and carbon steel pipe. It is not a copper or PEX fitting. For copper tube you want Viega's ProPress copper line instead, and for PEX the PureFlow line.
3) Is the Viega 25935 a threaded or welded tee?
Neither. It is a press fitting, connection type P1 x P2, so it is installed cold with a press tool and jaw sized to the pipe. No threading, no cutting oil, no hot work permit on the job.
4) I need a 1 inch branch off a 1 inch line, not 1/2 inch. Is this the right tee?
No. Model 25935 reduces the branch to 1/2 inch, so a 1 inch outlet will not fit it. You need the straight 1 inch x 1 inch x 1 inch MegaPress tee instead, or a different reducing configuration that matches your branch size.
5) What does Smart Connect mean on this Viega MegaPress tee?
Smart Connect is the feature in the sealing element that lets an unpressed joint leak intentionally during pressure testing, so an installer finds a missed connection before the system is signed off rather than after the ceiling is closed.
6) How much space do I need around the 1 x 1/2 inch MegaPress tee to fit it in?
The fitting body measures 3.791 inches long and 1.78 inches in both height and width, and weighs 0.486 lbs. Allow clearance beyond that for the press tool jaw to seat square on each socket, which is usually the limiting factor in tight joist bays or against a wall.
7) Where is the Viega MegaPress 25935 fitting made?
Made in Germany. That matters on public and institutional work where country of origin has to be documented in the submittal package.
8) Does the Viega 25935 come as one piece or do I order sealing elements separately?
It ships as a complete fitting with the sealing element already installed in each socket. Nothing else is supplied with it, so the press tool, the correct jaws, and pipe prep are on you.
