Viega 90745 – Frequently Asked Questions
1) What kind of connection does the Viega 90745 MegaPress adapter have on each end?
The 90745 is a P x FPT adapter: one end is a MegaPress press connection, the other is female pipe thread. So it presses onto the pipe on one side and takes a male-threaded nipple, valve, or component on the other. That makes it the transition piece when you are running press on the line but have to land on a threaded device.
2) Is the Viega 90745 MegaPress fitting carbon steel or stainless?
It is 316 stainless steel, not carbon steel. 316 is the higher-corrosion-resistance grade, which is why this one gets specified on lines where a carbon steel press fitting would not hold up. If your run is black iron or carbon steel press, this is a different material family and it should be reviewed against the piping spec before you mix it in.
3) What size pipe does the Viega 90745 adapter fit?
It is a 3 inch by 3 inch fitting, so the press end suits 3 inch pipe and the threaded end is 3 inch FPT. Both sides are the same nominal size, so there is no reduction through this fitting.
4) What is Smart Connect on the Viega 90745 and why does it matter on an inspection?
Smart Connect is the feature built into the MegaPress fitting that lets an unpressed connection leak intentionally during pressure test, so a joint you missed shows itself before the system is closed in. On a 3 inch stainless line with a lot of joints, that is the difference between finding the miss at test and finding it in a finished ceiling.
5) Does the Viega 90745 need thread sealant on the FPT side?
The press end seals on its own once it is pressed. The female threaded end is a conventional pipe thread joint, so it needs sealant or tape appropriate to the service, same as any FPT connection. Budget for the male nipple or threaded component separately, since only the fitting is supplied.
6) Where is the Viega 90745 MegaPress fitting manufactured?
Made in Germany. That matters for buyers on projects with country-of-origin reporting or a domestic-preference clause, since a German-made fitting will not satisfy a domestic sourcing requirement.
