Viega 91105 – Frequently Asked Questions
1) Is the Viega 91105 MegaPress coupling for 3/4 inch pipe on both ends?
Yes, the 91105 is a 3/4 inch by 3/4 inch coupling, so it joins two 3/4 inch runs of the same size. Both ends are press connections (P1 x P2), meaning each end gets crimped with a press tool rather than threaded or welded.
2) What does "with stop" mean on a MegaPress coupling, and when would I want one without a stop?
The stop is an internal shoulder that each pipe end butts against, so insertion depth is set for you and the two pipes cannot slide past center. That is what you want on a normal joint. For a repair in the middle of an installed line, where you cannot pull pipe apart to get insertion depth, a slip (no-stop) coupling is the one to order instead, since it slides along the pipe before pressing. The 91105 is the stop version.
3) Will the Viega 91105 hold up in a corrosive or wet mechanical room?
The body is 316 stainless steel, which is the more corrosion resistant of the common stainless grades thanks to its molybdenum content. That is why it gets specified for wash-down areas, coastal or chemical exposure, and service lines where a carbon steel fitting would rust at the joint.
4) What is Smart Connect on the Viega 91105 and why does it matter on a punch list?
Smart Connect is a deliberate feature in the sealing element that lets an unpressed joint leak during pressure test. The point is that an overlooked connection shows itself at test instead of after the ceiling is closed up. It does not replace walking the line, but on a large press job it is the reason a missed crimp gets caught the same day.
5) Do I need to thread or weld pipe to use the Viega 91105?
No. Both ends are press connections, so the joint is made cold with a press tool and jaw sized for 3/4 inch. No threading, no cutting oil, no hot work permit, which is the usual reason crews move to press on occupied buildings. You still need a square, clean, deburred pipe end and the correct jaw.
