Viega 91220 – Frequently Asked Questions
1) How does the Viega MegaPress 91220 adapter connect on each end?
The 91220 is a press-to-male-thread adapter: one end is a 1 inch MegaPress press socket, the other a 1 inch male pipe thread (P x MPT). You press the socket onto 1 inch carbon or stainless pipe with a MegaPress jaw and thread the other end into female NPT, so it is the transition fitting between a pressed run and threaded equipment, valves, or unions.
2) Is the Viega 91220 MegaPress adapter stainless or carbon steel?
It is 316 stainless steel throughout, which is the grade you want where the line sees corrosive media or a wet, washdown, or coastal environment. The fitting is made in Germany.
3) What is Smart Connect on the Viega MegaPress 91220 and why does it matter on a punch list?
Smart Connect is a deliberate feature in the sealing element that lets an unpressed connection leak during pressure test, so a joint you missed shows itself before the walls close up. On a large pressed system it is the difference between finding a skipped press at test and finding it after turnover.
4) How much space do I need to fit the Viega 91220 1 inch press adapter?
Plan on 3.02 inches overall length and 1.78 inches in height and width, and add room for the press jaw to close around the socket. It weighs 0.485 lbs, so no additional support is needed beyond normal pipe hangers.
5) Should I order a press-by-thread adapter or a press-by-press coupling for a 1 inch stainless run?
Use a press by press coupling where pipe joins pipe. Choose this P x MPT adapter only at the point where the run has to land on a female threaded port, such as a threaded valve, gauge, pump connection, or a union for future service. Mixing them up means either an unthreadable joint or an unnecessary thread in the middle of a pressed run.
