Viega V25950 – Frequently Asked Questions
1) What pipe sizes does the Viega MegaPress 25950 reducing tee connect?
The 25950 MegaPress tee is a 1-1/4 inch x 1 inch reducing tee in carbon steel, built for press connections on both ends (P1 x P2). It is Viega model 4815.2. Use it where a 1-1/4 inch carbon steel run needs to branch or step down to 1 inch rather than carrying full size through.
2) Can I use the Viega 25950 MegaPress fitting on copper or PEX?
No. This is a carbon steel press fitting intended for carbon steel pipe systems. Copper and PEX need their own press systems (Viega ProPress for copper, PureFlow for PEX). Putting a carbon steel MegaPress fitting on copper tube is the wrong material pairing and the wrong press jaw.
3) Do I need threading or welding to install a 1-1/4 x 1 MegaPress reducing tee?
No threading, no welding, no flame. Both ends of the 25950 are press connections, so the joint is made cold with a press tool and the correct jaw for the size. That is the main reason crews choose MegaPress over threaded or welded black steel on occupied buildings where hot work permits are a problem.
4) How much clearance do I need around the Viega 25950 tee in a tight ceiling or chase?
The fitting itself measures 4.394 inches long, 2.205 inches wide and 2.205 inches high, and weighs 0.804 lbs. Allow space beyond that for the press jaw to open and rotate around the fitting, which is usually the real constraint in a chase or above a ceiling grid rather than the fitting body.
5) What does Smart Connect do on a MegaPress fitting?
Smart Connect is Viega's unpressed-connection feature. A fitting that has not been pressed will leak visibly during pressure testing, so an inspector or installer can spot a missed joint before the system is buried or covered. It is a quality control aid, not a seal, and every joint still has to be pressed.
6) Should I use a reducing tee or a full-size tee with a reducer bushing for a 1-1/4 to 1 inch branch?
A single 1-1/4 x 1 reducing tee like the 25950 does the job in one press joint rather than a full-size tee plus a separate reducing coupling, which means fewer joints to press, fewer to inspect and less take-out length. Go with a full-size tee only if you want the branch left at 1-1/4 inch for a future tie-in.
7) What part number do I order for the Viega 1-1/4 x 1 MegaPress reducing tee?
Order Viega 25950. The same fitting is catalogued by Viega as model 4815.2, which is how it often appears on European-format submittals and price lists. Both refer to the 1-1/4 inch x 1 inch carbon steel press reducing tee.
8) Is the Viega 25950 MegaPress tee made in Germany?
Yes, the 25950 is manufactured in Germany. For submittal packages that require country of origin on piping components, it lists as Made in Germany, carbon steel construction, Viega model 4815.2.
