Viega 90585 MegaPress tee Smart Connect technology 316 stainless steel, 3'' x 3'' x 2''

The 90585 is a reducing tee sized 3 inch x 3 inch x 2 inch, so the run is 3 inch on both ends with a 2 inch branch outlet. All three ends are press connections (P1 x P2 x P3), meaning no threading, welding or soldering at any of the three joints.

It is made from 316 stainless steel, the grade specified where chloride exposure or washdown chemicals would attack carbon steel or 304. That makes it a fit for food and beverage plants, coastal mechanical rooms, and process lines where the piping itself is stainless.

No. The 90585 is a 316 stainless steel press fitting and belongs on stainless pipe of matching size. Pressing a stainless fitting onto carbon steel pipe mixes metals at the joint and is not the intended application; for black iron or carbon steel runs you want the carbon steel MegaPress fittings, and for copper a ProPress copper fitting.

Smart Connect is a feature of the sealing element that leaks visibly when the joint is left unpressed during a pressure test. On a tee like the 90585 that is three separate joints to verify, so it's a practical way to catch a missed press on a 3 inch stainless line before the ceiling closes up.

Manufacturer part number 90585, a Viega MegaPress tee in 316 stainless, made in Germany. That MPN is what to quote on a submittal or a reorder so you don't get the carbon steel equivalent.

A press tee like the 90585 makes all three joints cold, with no hot work permit, no purge, and no weld inspection, which is why it gets specified for occupied buildings and retrofit tie-ins. Welding still wins where the system pressure or temperature exceeds the press fitting's rating or where a continuous-material joint is required by the spec. For a mechanical room branch off an existing 3 inch stainless main, pressing is the faster route.

3.963 lbs for the fitting alone. Add that to the filled weight of the 3 inch stainless run when you set hanger locations; a tee this size generally wants support close to the branch rather than letting the fitting hang between hangers.
