Viega 25595 – Frequently Asked Questions
1) What does the Viega MegaPress 25595 fitting connect to on each end?
The 25595 MegaPress adapter is a P x FPT fitting: one end is a press connection, the other is female pipe thread. So it presses onto carbon steel pipe on the press side and takes a male-threaded nipple, valve, or gauge on the threaded side. That's the transition you use when you're running pressed carbon steel and need to land on a threaded device.
2) What sizes are the press end and the threaded end on Viega 25595?
It's a 1-1/4 inch x 3/4 inch adapter. Pair that with the P x FPT connection type and you're pressing the larger carbon steel side and threading the smaller side. If your run and your device are both the same size, this reducing adapter is the wrong part.
3) Is the Viega 25595 MegaPress adapter carbon steel or stainless?
Carbon steel. That matters for the system you're pressing into: carbon steel MegaPress fittings go on black iron / carbon steel pipe, not on copper and not as a substitute for a stainless fitting in a corrosive or potable application. Match the fitting metal to the pipe metal.
4) How much room do I need to fit a MegaPress 1-1/4 x 3/4 adapter in a tight mechanical space?
The 25595 adapter measures 3.484 inches long by 2.205 inches wide by 2.205 inches high and weighs 0.67 lbs. Use the length figure when you're laying out a run against a wall or in a joist bay, and remember the press tool jaw needs clearance around the fitting on top of the fitting's own footprint.
5) Do I still need thread sealant on the FPT side of a MegaPress adapter?
Yes on the threaded side. The press end of the 25595 seals mechanically when you crimp it, but the 3/4 inch FPT side is a standard female pipe thread and gets made up the normal way with tape or pipe dope on the male thread going into it. The press connection is the only joint on this fitting that a tool makes.
6) Can I install the Viega 25595 by hand, or do I need a press tool?
A press tool is required. The P side of the 25595 is a MegaPress connection, which is made with a press tool and the correct jaw for the 1-1/4 inch press size. There is no solder, no thread, and no way to make that joint by hand. Only the 3/4 inch FPT end is made up with a wrench.
7) What is the manufacturer part number for the Viega MegaPress 1-1/4 x 3/4 FPT adapter, and where is it made?
Order it as Viega part 25595. It's made in Germany. If you're standardizing a mechanical room or building a submittal, 25595 is the number to put on the sheet for the 1-1/4 inch press by 3/4 inch FPT carbon steel adapter.
8) I need to branch off a 1-1/4 inch line, not just adapt it. Is 25595 the right fitting?
No, if you need a branch. The 25595 is a two-end adapter, press on one side and 3/4 inch female thread on the other, so it terminates or transitions a line rather than splitting it. For a branch off a 1-1/4 inch carbon steel run you want a MegaPress tee in the corresponding sizes.
