Viega 91800 – Frequently Asked Questions
1) Will a 316 stainless MegaPress elbow hold up on a chilled water or industrial line?
The 91800 is made from 316 stainless steel, the grade used where chloride exposure and corrosion resistance matter more than plain carbon steel can handle. Stainless MegaPress fittings are for stainless pipe systems, not a substitute for the carbon steel MegaPress line on black iron pipe.
2) Is the Viega 91800 elbow 1-1/4 inch on both ends?
Yes, it is 1-1/4 inch by 1-1/4 inch, so no size change through the turn. One end is the male fitting spigot and the other is the press end for 1-1/4 inch pipe.
3) How much room do I need to fit the Viega 91800 45 degree street elbow?
Plan for roughly 5.461 inches by 3.768 inches by 2.205 inches of envelope, and leave clearance beyond that for the press tool jaw to seat squarely on the press end. Tight chases are usually a jaw-access problem before they are a fitting-size problem.
4) What is Smart Connect on this Viega press fitting and why does it matter on inspection?
Smart Connect is Viega's unpressed-connection feature: an unpressed joint leaks deliberately during pressure testing so the installer finds the missed connection before the wall closes. On a long run of 1-1/4 inch stainless, that is what keeps a single skipped press from becoming a callback.
5) Do I need a sealant or thread dope on the Viega 91800?
No. Both ends are press, not threaded, so nothing is doped or taped. The press end seals on a sealing element compressed by the tool, and the FTG spigot end is pressed inside the mating fitting's socket. Pipe just needs to be cut square, deburred, and marked to full insertion depth.
