Viega 84240 MegaPress coupling With stop Smart Connect technology Carbon steel, 2'' x 2''

The MegaPress 84240 is a 2 inch by 2 inch coupling, so it joins two lengths of 2 inch pipe. Both ends are press connections (P1 x P2), pressed with a MegaPress jaw rather than threaded or welded.

A coupling with a stop has an internal shoulder in the middle, so each pipe end bottoms out at a fixed insertion depth. That makes it the standard choice for new runs where you can bring both pipes to the fitting. A coupling without a stop (a slip or repair coupling) lets the fitting slide along the pipe, which is what you need when both pipes are already fixed in place and you are tying into or repairing an existing 2 inch line. The 84240 is the with-stop version.

It is a straight 2 inch by 2 inch coupling, joining two pipes in line. It has two press ends, not three outlets, so if you need a branch off a 2 inch carbon steel run you want a MegaPress tee instead.

Carbon steel. That is the MegaPress line for black iron and carbon steel pipe systems, not the stainless MegaPressG or copper ProPress families. It is made in Germany.

The coupling body itself measures 4.748 inches long and 2.894 inches across, so plan clearance beyond that for the press jaw to wrap the pipe and close. In tight ceiling or wall cavities, check the jaw envelope for your tool before you commit to the location.

No. Both ends are press connections, so the pipe is cut, deburred, marked for depth and pressed cold. No threading, no cutting oil, no hot work permit. You do need a MegaPress-rated press tool and the correct 2 inch jaw, which are not part of the fitting.

Smart Connect is Viega's feature that leaves an unpressed connection deliberately leaky during pressure testing, so a joint you forgot to press shows itself instead of hiding until the system is in service. On a 2 inch coupling with two press ends, that means both joints get verified on test.
