Viega 26660 – Frequently Asked Questions
1) What connections does the Viega MegaPress 26660 adapter have on each end?
The Viega MegaPress 26660 is a P x FPT carbon steel fitting: one press end and one female pipe thread end, both at 3 inch. So it presses onto 3 inch black iron or carbon steel pipe on one side and takes a 3 inch male threaded nipple, valve, or gauge fitting on the other. That makes it the transition piece where a pressed run has to meet existing threaded pipe or a threaded device.
2) Will the Viega 26660 work on copper or PEX?
No. The 26660 is a carbon steel MegaPress fitting, sized for 3 inch carbon steel pipe such as black iron. Copper tube and PEX use entirely different Viega systems and different press jaws. Use it only where the pipe on the press side is carbon steel.
3) Do I need to thread or weld pipe to install the Viega 26660 MegaPress adapter?
No cutting oil, no threading machine, and no torch on the press side. The 26660 has a 3 inch press end that is made up cold with a press tool, and a 3 inch female threaded end for the side that has to stay threaded. On a retrofit that means you only thread what is already threaded and press the rest, which is why crews use it to tie new carbon steel runs into existing systems without hot work.
4) Can I use the 26660 to connect a threaded valve into a pressed carbon steel line?
That is exactly what it is for. The female thread end accepts a 3 inch male threaded valve, nipple, or trim item, and the press end joins the 3 inch carbon steel pipe. Standard practice is to make up the threaded side first and press last, so the joint is not being twisted after the press is set.
5) Is the Viega 26660 a tee or a straight adapter?
Ordering-wise, Viega catalogs part 26660 as a MegaPress adapter in carbon steel, 3 inch by 3 inch, with a press end and an FPT end. Order it by the Viega part number 26660 so there is no ambiguity on the submittal or the counter ticket.
6) Where is the Viega 26660 MegaPress fitting made?
Germany. For public and institutional jobs with country-of-origin language in the spec, the 26660 carbon steel MegaPress fitting is made in Germany, which is worth confirming against your project's procurement requirements before the submittal goes in.
