Viega 26650 – Frequently Asked Questions
1) What kind of connection does the Viega MegaPress 26650 adapter have on each end?
The 26650 is a press-by-male-thread adapter: one end is a MegaPress press connection that goes onto the pipe with a press tool, the other is male pipe thread (MPT) for a threaded joint. So it's the transition fitting you use when you're running pressed carbon steel and need to land on a threaded valve, union, or piece of equipment.
2) Will the Viega 26650 MegaPress adapter work on copper or PEX?
No. This adapter is carbon steel and is built for the MegaPress system, which presses onto carbon steel pipe. For copper you need a copper press fitting system, and PEX needs its own fittings entirely. Putting a carbon steel press fitting on copper is the wrong material pairing.
3) What size pipe does the Viega 26650 adapter fit?
It's a 4 inch by 4 inch fitting, so the press end takes 4 inch carbon steel pipe and the threaded end is 4 inch male pipe thread. Same size both ends, no reduction.
4) What does Smart Connect technology on this Viega MegaPress fitting actually do for me on site?
Smart Connect is Viega's unpressed-joint feature. An unpressed connection leaks visibly during pressure testing so you can find it and press it, rather than discovering a missed joint after the walls are closed. On a large 4 inch run with a lot of joints, that's the feature that keeps a punch list short.
5) Do I need any other parts or sealant to install the Viega 26650?
Two different jobs on two ends. The press side seals on the factory-installed sealing element inside the fitting, so nothing gets added there, just a properly cut, deburred and marked pipe end and a 4 inch MegaPress jaw on the press tool. The male thread side is a conventional threaded joint and takes whatever thread sealant or tape your spec calls for. The press tool and 4 inch jaw or ring are not supplied with the fitting.
6) Where is the Viega 26650 MegaPress fitting made?
Made in Germany. If you're submitting on a job with country-of-origin documentation requirements, that's the origin to put on the submittal for this fitting.
7) What is the manufacturer part number for the 4 inch Viega MegaPress press-by-male-thread adapter?
Viega part number 26650. That's the number to quote for the 4 inch by 4 inch carbon steel MegaPress adapter with a male thread outlet, and it's what a distributor will look up.
