Viega 91685 MegaPress tee Smart Connect technology 316 stainless steel, 2'' x 2'' x 1''

The Viega 91685 MegaPress tee is a 2 inch x 2 inch x 1 inch reducing tee, so the run is 2 inch on both ends and the branch outlet takes 1 inch pipe. All three ends are press connections (P1 x P2 x P3), so no threading or welding on any of the three joints.

It's 316 stainless steel, not carbon. That matters on the job: 316 is the grade you reach for where the line or the environment is corrosive, such as wash-down areas, coastal mechanical rooms, or chemical and process piping. If you are pressing black iron gas or hydronic lines, the carbon steel MegaPress fittings are the match for that pipe instead.

Smart Connect is a feature of the sealing element that deliberately leaks a small amount at an unpressed connection, so when you pressure test the system an unpressed joint shows itself rather than hiding behind the pipe. On a 2 inch x 2 inch x 1 inch tee with three separate press joints that is three chances to miss one, which is exactly where the feature pays off on a punch list.

No threading or welding is needed. All three outlets on the 91685 are press (P1 x P2 x P3), so a 1 inch branch comes off a 2 inch run with a press tool and jaws sized for each connection. That is the usual reason crews pick MegaPress over a weld-o-let or a threaded tee: no hot work permit and no pipe threading on site.

Order Viega part number 91685. That is the manufacturer part number for the 316 stainless MegaPress tee in the 2 inch x 2 inch x 1 inch configuration, and it is the number to quote so you don't end up with the carbon steel version or a full-size 2 inch branch.

It's made in Germany. Worth knowing up front if you are filling a government, healthcare, or federally funded institutional order with domestic sourcing language in the spec, since the country of origin on this tee is Germany.
