Viega 91115 – Frequently Asked Questions
1) Will the Viega MegaPress 91115 coupling work on 1-1/4 inch black iron pipe?
The Viega MegaPress 91115 is a 1-1/4" x 1-1/4" press coupling with two press ends (P1 x P2), so it joins two runs of 1-1/4 inch nominal pipe. It is built in 316 stainless steel, which is the corrosion resistant body material rather than carbon steel.
2) What does "with stop" mean on a MegaPress coupling, and when would I want one without a stop?
A coupling with a stop has an internal shoulder in the middle, so each pipe end butts against it and seats at a fixed insertion depth. That is what you want for new runs where you can bring the pipe to the fitting. On a repair where both pipes are already fixed in place and you need to slide the coupling along one of them, you need a coupling without a stop instead. The 91115 is the with-stop version in 1-1/4 inch.
3) Is the Viega 91115 a tee or a straight coupling? The part data is confusing.
It is a straight coupling, 1-1/4" x 1-1/4", with a press end on each side (P1 x P2). It joins two pipes in line. If you need to branch a line, you want a MegaPress tee, not this part.
4) What is Smart Connect on the Viega 91115 and why does it matter on inspection?
Smart Connect is a feature of the sealing element that lets an unpressed joint leak visibly when the system is filled and tested. On a 1-1/4 inch MegaPress coupling like the 91115, that is how you find a connection the crew missed before the wall closes up, instead of discovering it later.
5) Why choose a 316 stainless MegaPress coupling instead of a carbon steel one?
316 stainless is the choice where the pipe or the environment is corrosive, wet, or washdown, and on systems where carbon steel bodies are not acceptable to the spec. The 91115 body and the fitting material are both listed as 316 stainless steel. If your drawing calls out stainless press fittings, this is the 1-1/4 inch coupling that meets it.
6) How much room do I need around the pipe to fit the Viega 91115 coupling?
The fitting itself measures 4.417 inches long with a 2.205 inch height and 2.205 inch width, so plan clearance for that envelope plus the jaw of your press tool. In tight joist bays or close to a wall, the press tool swing, not the fitting, is usually what decides whether you can make the connection.
7) Do I need to order anything else to install the Viega MegaPress 91115?
No threading, no welding, no solder. You need a Viega-approved press tool with the correct 1-1/4 inch MegaPress jaw or ring, and pipe cut square and deburred. The sealing element comes installed in the coupling, so nothing is ordered separately with the fitting itself.
