Viega 91780 – Frequently Asked Questions
1) Is the Viega 91780 elbow threaded or press fit?
Both ends are press connections, listed as P1 x P2, so no threading, grooving, or welding is needed. You cut the pipe square, deburr, mark the insertion depth, and press with a MegaPress jaw sized for 2 inch. There are no threaded or sweat outlets on this fitting, so if you need to tie into a threaded nipple you will want a press x thread adapter instead.
2) Will a 316 stainless press elbow work for a corrosive or outdoor line?
The 91780 is made from 316 stainless steel, which is the grade Viega uses for its more corrosion-resistant MegaPress fittings. That makes it the choice where the standard carbon steel MegaPress body would be at risk, such as damp mechanical rooms, exterior runs, or lines carrying media that attack carbon steel. The fitting itself is made in Germany.
3) How much space do I need to fit the Viega 91780 45 degree elbow in a tight chase?
Plan for a footprint of 6.618 inches long, 4.783 inches wide, and 2.894 inches high. On top of that you need clearance for the press jaw to close squarely around each end, so measure your chase or joist bay for the tool, not just the fitting. The elbow weighs 1.622 lbs, light enough to hold in place while pressing.
4) What does Smart Connect do on this MegaPress elbow?
Smart Connect is the feature built into the 91780 that lets an unpressed connection weep when the system is pressurized, so a joint you missed shows itself during testing rather than after the ceiling closes. It is a verification aid, not a substitute for pressing every joint to the jaw's full cycle.
5) Should I use a 45 degree elbow or two 90s to offset a 2 inch steel line?
A pair of 45s is the normal way to jog around an obstruction while keeping flow smoother and pressure loss lower than stacked 90s. The 91780 gives you that 45 degree change of direction in 2 inch with press ends on both sides, so each offset leg costs you two presses and a short nipple between them. Use 90s when you need a true square turn at a wall or riser.
