Viega 25340 – Frequently Asked Questions
1) What size pipe does the Viega 25340 MegaPress tee fit?
The 25340 MegaPress tee is a reducing tee sized 1 inch x 1 inch x 3/4 inch. The run presses onto 1 inch carbon steel pipe at both ends, and the branch takes 3/4 inch. If you need the branch full size, this is not the fitting, look for the 1 x 1 x 1 straight tee instead.
2) Can I use a MegaPress carbon steel tee on black iron gas or hydronic pipe instead of threading it?
That is exactly what MegaPress carbon steel fittings are for. The 25340 is a press fitting made of carbon steel, so it goes on black or galvanized carbon steel pipe without cutting threads or welding. You still need the pipe cut square, deburred, and marked to insertion depth, and you need the matching press tool and jaws for the 1 inch run and 3/4 inch branch. Nothing about a press connection is field-adjustable after the crimp, so set the fitting orientation before you press.
3) Will a MegaPress carbon steel tee work on copper or PEX?
No. The 25340 is carbon steel and presses onto carbon steel pipe. Copper tube takes a copper press fitting (Viega ProPress), and PEX takes a PEX fitting system. Putting a carbon steel press fitting on copper is the wrong seal geometry and the wrong material pairing, so match the fitting family to the pipe you are running.
4) What does Smart Connect technology on a Viega MegaPress fitting actually do?
Smart Connect is Viega's unpressed-connection feature: an unpressed fitting leaks during pressure test so you find the joint you skipped before the wall closes up. On a tee like the 25340 that matters more than on a coupling, because a tee has three separate presses and a missed branch press is easy to walk past.
5) How is the connection on the 25340 tee described, press or threaded?
All three ends are press connections, listed as P1 x P2 x P3. There is no thread on this fitting, so if you need to land on a threaded valve or a union you will need a press-by-thread adapter downstream of the tee.
6) How much room do I need to fit a Viega 1 x 1 x 3/4 MegaPress tee in a joist bay or chase?
The 25340 tee measures 5.15 inches long, 3.291 inches wide, and 1.78 inches high. Lay that out against your bay before you cut pipe, and remember the press jaws need clearance around the fitting body on all three ends, not just the fitting footprint itself.
7) What is the manufacturer part number for the Viega MegaPress 1 x 1 x 3/4 carbon steel tee?
Viega part number 25340. That is the number to quote for the carbon steel MegaPress reducing tee at 1 inch x 1 inch x 3/4 inch. The fitting is made in Germany.
8) How much does a Viega 25340 MegaPress tee weigh for takeoff and hanger spacing?
Each 25340 tee weighs 0.957 lbs. For a large fitting count that adds up quickly on a takeoff, and it is worth accounting for at hanger points where several fittings land close together.
