Viega 91940 – Frequently Asked Questions
1) What size pipe does the Viega MegaPress 91940 union press onto?
The 91940 MegaPress union is a 1-1/4 inch by 1-1/4 inch fitting, press on both ends (P1 x P2). Both sides press directly onto 1-1/4 inch carbon or stainless pipe with a MegaPress jaw, so there is no threading and no welding on either side of the union.
2) Is the Viega 91940 union stainless steel or carbon steel?
It is 316 stainless steel. That is the grade to specify where the line sees corrosive or washdown conditions rather than plain dry mechanical service, and it is the reason this union costs more than a carbon steel MegaPress fitting of the same size.
3) Does the Viega 91940 have Smart Connect, and what does that actually do on the job?
Yes, the 91940 is a Smart Connect fitting. An unpressed connection will leak deliberately during pressure test, so a joint you missed on a long run shows itself at test instead of after the ceiling is closed. It does not make an unpressed joint safe to leave, it only makes it findable.
4) Why use a press union instead of just pressing a coupling in the line?
A union gives you a break point you can take apart later. A MegaPress coupling is permanent once pressed, so if the run serves a pump, valve, or piece of equipment that will come out for service, put the 1-1/4 inch 91940 union on either side of it. For a straight run with nothing to service, a coupling is the cheaper and shorter option.
5) How much space do I need to fit the Viega 91940 union in a tight chase?
Plan on roughly 6.524 inches of length, 2.992 inches wide and 2.756 inches high for the fitting body. That is before the press tool, which needs clearance around the pipe on both sides of each press ring, so a chase sized only to the fitting will not work.
6) Where is the Viega 91940 MegaPress union made?
Germany. Buyers on federal, state, or institutional jobs with domestic-content language on the drawings should check that country of origin against the spec before it goes in the wall.
7) What is the Viega part number to order for a 1-1/4 inch stainless MegaPress union?
Order Viega 91940. That is the manufacturer part number for the 1-1/4 inch by 1-1/4 inch 316 stainless MegaPress union with Smart Connect.
