Viega 91640 – Frequently Asked Questions
1) Is the Viega 91640 tee press-fit or threaded?
Press. All three outlets are press connections (P1 x P2 x P3), joined with a MegaPress jaw and press tool rather than threading, grooving or welding. No open flame is needed, which is why it gets used in occupied buildings and mechanical rooms where hot work permits are a problem.
2) Will a 316 stainless MegaPress tee hold up in a corrosive or washdown environment?
The 91640 tee body is 316 stainless steel, the grade specified where chlorides and washdown chemicals attack carbon steel or 304. That makes it a fit for food plants, coastal mechanical rooms, laboratories and process piping. If your system is plain black iron carbon steel, the carbon steel MegaPress line is the matching fitting.
3) What does Smart Connect technology do on this Viega tee?
Smart Connect is Viega's unpressed-connection feature: the sealing element is shaped so an unpressed joint leaks deliberately during pressure testing, letting you find a missed press before the system is charged and the ceiling is closed. On a three-outlet fitting like the 1-1/4 inch 91640 that matters, because there are three separate presses to miss.
4) How much space do I need to fit the Viega 91640 MegaPress tee between hangers?
Plan the rough-in around 6.535 x 4.343 x 2.205 inches overall for the fitting body, plus clearance for the press jaw to swing fully around each of the three outlets. Tight joist bays and close-spaced racked pipe are where crews get caught: the jaw, not the fitting, sets the real space requirement.
5) Do I need anything besides the tee to make up the joint?
The 91640 ships as a complete press tee with its sealing element already installed, so no gaskets, solder, flux or thread sealant are required. What you do need on the job is a press tool with the correct MegaPress 1-1/4 inch jaw, plus a proper square pipe cut and a deburred, marked pipe end before pressing.
6) Is the Viega 91640 tee the exact part number my spec calls out, and where is it made?
Manufacturer part number 91640 is Viega's 1-1/4 inch MegaPress 316 stainless tee, made in Germany. Distributors and submittal reviewers should note the full size callout is 1-1/4 x 1-1/4 x 1-1/4, which separates it from the reducing tees in the same series that share similar numbering.
