Viega 26665 – Frequently Asked Questions
1) What kind of connection does the Viega MegaPress 26665 adapter have on each end?
The Viega 26665 is a press by female pipe thread adapter, P x FPT. One end presses onto the pipe with a MegaPress tool and jaw, the other takes a male-threaded fitting or nipple. That makes it the transition piece when you need to get from pressed carbon steel pipe onto a threaded component like a valve, gauge or union.
2) Is the Viega 26665 MegaPress fitting suitable for black iron gas or hydronic pipe?
It is a carbon steel fitting, so it is intended for use on carbon steel (black) pipe systems rather than copper or stainless lines. Match the fitting material to the pipe material; a carbon steel press fitting is not a substitute for a copper press fitting on a copper system.
3) What size is the Viega 26665 MegaPress adapter?
The 26665 is listed at 4 inch by 4 inch, so both the press end and the female threaded end are 4 inch. It is a straight-size adapter, not a reducer, so the thread you land on has to be 4 inch NPT as well.
4) Do I still need to thread or weld anything when I use a MegaPress adapter?
Only on the threaded side. The press end goes on cold with a press tool, no cutting oil, no threading, no hot work. The FPT side is a conventional female NPT thread, so whatever you screw into it still needs thread sealant or tape and a wrench.
