Viega 25330 – Frequently Asked Questions
1) What size pipe does the Viega 25330 MegaPress tee fit?
The 25330 MegaPress tee is a reducing tee sized 3/4 inch x 3/4 inch x 1/2 inch, so the run stays 3/4 inch end to end and the branch drops to 1/2 inch. Use it where you're pulling a 1/2 inch takeoff off a 3/4 inch line rather than where all three ports need to match.
2) Is the Viega 25330 tee carbon steel or copper, and what lines can it go on?
Carbon steel. The 25330 is a MegaPress carbon steel fitting, which is the black iron pipe side of the Viega press line, not the copper ProPress side. Put it on carbon steel pipe; for copper tube you need a ProPress fitting instead.
3) Does the Viega 25330 MegaPress tee thread on or does it get pressed?
All three ports are press connections, shown as P1 x P2 x P3 in the spec. There are no threads on this fitting. You cut the pipe, deburr, mark depth, slip the fitting on and press it with a press tool and the matching MegaPress jaw or ring. No threading, no soldering, no open flame.
4) What does Smart Connect technology do on a Viega MegaPress fitting?
Smart Connect is a feature built into the sealing element so that an unpressed connection leaks during pressure testing instead of holding. On a repipe with dozens of joints, that's how you find the one you skipped before the ceiling closes up. It does not change how the joint is made, only how a missed press shows itself.
5) How much clearance do I need to fit a 3/4 x 3/4 x 1/2 MegaPress tee in a joist bay?
The fitting body measures 4.528 inches long, 2.886 inches wide and 1.496 inches high, and it weighs 0.639 lbs. Those are the fitting dimensions only, so allow extra room beyond that for the press jaw to open and rotate around the port you're pressing.
6) Can I press a MegaPress tee into an existing carbon steel line without draining the whole system?
Pressing a MegaPress fitting is a cold, flameless connection, so there's no hot work permit and no torch in an occupied building. The line itself still has to be cut, drained at the work area and the pipe ends cleaned and deburred before the tee goes on, so plan the isolation the same way you would for a threaded takeoff.
7) Which port on the Viega 25330 tee is the 1/2 inch one?
The 1/2 inch is the branch. The 25330 is designated 3/4 x 3/4 x 1/2, which reads run, run, branch, so the two 3/4 inch ports are in line with each other and the 1/2 inch outlet comes off the side. If you need the reduction in the run instead of the branch, this is the wrong tee.
8) What is the manufacturer part number for the Viega MegaPress 3/4 x 3/4 x 1/2 tee?
Viega part number 25330. That single model covers the 3/4 x 3/4 x 1/2 carbon steel MegaPress tee, and it is made in Germany. Order by 25330 and you will not land on the equal-outlet 3/4 tee by mistake.
