Viega 91255 – Frequently Asked Questions
1) What kind of connection does the Viega 91255 MegaPress adapter have on each end?
It's a P x FPT fitting: one 1-1/4 inch MegaPress press end that goes onto the pipe, and one 1-1/4 inch female NPT thread for a male-threaded nipple, valve, or union. So you press one side and thread the other, no soldering or threading of the pipe end.
2) Is the Viega 91255 press adapter stainless or carbon steel, and does that matter for my system?
The body is 316 stainless steel. That's the alloy to use where you're running stainless pipe or where corrosion is a concern, and it also means you should not use it as a substitute for a carbon steel MegaPress fitting on black iron pipe systems where the spec calls for carbon steel. Match the fitting alloy to the pipe you are pressing.
3) Can I use a female-thread MegaPress adapter to tie press pipe into a threaded valve or existing threaded line?
That's exactly what it's for. The FPT end takes a male NPT thread, so you can land a threaded ball valve, gauge, nipple, or an existing threaded stub into a pressed run. Use pipe dope or PTFE tape on the threaded joint; the press side needs no sealant.
4) What does Smart Connect technology on the Viega 91255 actually do for me on the job?
Smart Connect is Viega's unpressed-connection feature: before pressing, the sealing element is intentionally designed to let a small amount of fluid escape so an unpressed joint shows itself during pressure test. On a large stainless run with dozens of joints, that's what keeps you from closing a ceiling over a missed press.
5) Is the Viega 91255 a tee or a straight adapter?
It's a two-end adapter, press by female thread, both ends 1-1/4 inch. If you need to branch a 1-1/4 inch stainless press line in three directions, you want a MegaPress 316 tee instead, not this fitting.
6) Do I need a special press tool jaw for this 1-1/4 inch MegaPress fitting?
Yes, MegaPress joints are made with a press tool and the jaw or ring sized for the fitting, so you need 1-1/4 inch MegaPress jaws. The fitting's 1-1/4 inch press end will not seal with a copper ProPress jaw of nominally the same size, and the connection has to be pressed to be permanent.
7) Where is the Viega 91255 MegaPress fitting made?
Made in Germany. For spec packages and government or institutional submittals that ask for country of origin on each line item, that's the value to report for this fitting.
