Viega 91770 – Frequently Asked Questions
1) What pipe size does the Viega MegaPress 91770 45-degree elbow fit?
The MegaPress 91770 is a 1-1/4 inch by 1-1/4 inch 45-degree elbow, press on both ends (P1 x P2). It presses onto 1-1/4 inch carbon steel or black iron pipe, so both legs take the same size, no reducing.
2) Is the Viega 91770 elbow stainless steel or carbon steel?
It is 316 stainless steel. That matters if you are joining a stainless line or working somewhere corrosive, and it also means you should not use a carbon steel MegaPress fitting in its place on a stainless run.
3) Do I need to thread or weld pipe to install a MegaPress 45-degree elbow?
No. The 91770 is a press fitting on both ends, so the joint is made cold with a press tool and the correct 1-1/4 inch jaw or ring. No threading, no cutting oil, no hot work permit. Pipe ends still need to be cut square, deburred, and marked to full insertion depth before pressing.
4) What does Smart Connect on the Viega 91770 actually do for me on the job?
Smart Connect is a feature of the MegaPress sealing element that lets an unpressed connection leak intentionally during pressure testing, so an accidentally missed joint shows up on the test rather than after the ceiling is closed. On a large run of 1-1/4 inch elbows and couplings that is the main safeguard against a skipped press.
5) How much space does this 1-1/4 inch 45-degree press elbow take up in a tight chase?
Overall it measures 5.543 x 3.85 x 2.205 inches and weighs 1.047 lbs. Plan clearance around the fitting for the press jaw as well, since the tool needs to close square on each end.
