Viega 25676 MegaPressG union Smart Connect technology Carbon steel, 2'' x 2''

The 25676 is a 2 inch MegaPressG carbon steel fitting with a P x FPT configuration: one press end that goes onto 2 inch carbon steel pipe with a press tool, and one female pipe thread end that takes a male-threaded 2 inch nipple, valve, or appliance connector. That mix is what you use where you want to press the run but land on a threaded component you may need to break loose later.

No. The 25676 is a carbon steel MegaPressG fitting, so the press end is sized and sealed for 2 inch carbon steel pipe. Copper tube and stainless pipe need the matching press system in that material, not this one. If your run is black iron or carbon steel schedule pipe at 2 inch, this is the right family.

Only at the threaded side. The FPT end unthreads from whatever male fitting is screwed into it, so that is your service point. The press end is permanent once it is crimped, and coming out of it means cutting the pipe and starting with a fresh fitting. Put the 25676 where you want that threaded break to be, such as at a valve, a regulator, or an appliance drop.

Plan on a body that measures 4.772 x 3.701 x 3.346 inches for the 25676, and then add clearance around it for the press jaw, which swings well past the fitting itself. In a tight ceiling or against a wall it is usually the tool, not the fitting, that decides whether you can make the connection in place.

Smart Connect is a feature of the sealing element that lets an unpressed connection make itself known during pressure testing rather than passing a walk-through and failing later. It is a verification aid, not a substitute for pressing: every joint on the 25676 still gets pressed with the correct 2 inch jaw before the system goes into service.

Order Viega 25676. That is the manufacturer part number for the 2 inch MegaPressG carbon steel press to female pipe thread fitting, made in Germany. Spec it by that number rather than by description, because MegaPress and MegaPressG parts look alike across the sealing element options.

At 3.295 lbs the 25676 adds real mass at the joint, and a 2 inch carbon steel run carries plenty of its own weight. Hang the pipe to your normal 2 inch spacing and keep a hanger near the fitting rather than letting it float mid-span, especially where the threaded end picks up a valve or a connector that someone will later put a wrench on.
