Viega 91165 MegaPress reducer Smart Connect technology 316 stainless steel, 2'' x 1''

The Viega 91165 is an FTG x P fitting, so one end is a fitting-end (street) that slides into the press socket of another fitting or component, and the other end is a press end that accepts pipe. That lets you go straight from a fitting outlet to the next run of pipe without an extra coupling. Both ends are pressed with the appropriate jaw, not threaded or welded.

It reduces 2 inch to 1 inch. The 2 inch side is the fitting end and the 1 inch side is the press end, per the FTG x P configuration, so it is used where a 2 inch line steps down to a 1 inch branch or continuation.

The 91165 is a reducer, not a tee: it has two ends, a 2 inch fitting end and a 1 inch press end, and it changes size in a straight run. If you need a 1 inch takeoff from a 2 inch main you want a reducing tee instead.

It is made from 316 stainless steel, the grade specified where chloride exposure and corrosion resistance matter, so it holds up better than carbon steel fittings in washdown areas, coastal plants, and chemical service. Keep in mind that the pipe and the seal material also have to suit the medium, not just the fitting body.

The fitting itself measures 4.512 inches long and 2.374 inches in both height and width. Add clearance for the press jaw around the press end, which is the real constraint in a tight chase, not the fitting body.

Smart Connect is the feature built into the MegaPress sealing element that lets an unpressed connection leak visibly during pressure testing. On a large job that means an unpressed joint shows up at test rather than after the ceiling is closed, which is the main reason crews pick MegaPress for retrofit work in occupied buildings.

No. MegaPress is a cold press system, so the 1 inch press end is made up with a press tool and jaw, and the 2 inch fitting end presses into the socket of the mating fitting. No torch, no threading, no pipe dope. That is what makes it workable in occupied or hot-work-restricted spaces.
