Viega 91290 – Frequently Asked Questions
1) What size pipe does the Viega 91290 MegaPress coupling fit?
The Viega 91290 is a 1/2 inch x 1/2 inch coupling, so it joins two 1/2 inch pipe ends. Both ends are press connections (P1 x P2), not threaded.
2) What does "no stop" mean on the Viega 91290 coupling?
A no-stop coupling has no internal tube stop in the middle, so the fitting can slide freely along the pipe. That is what you want for a repair: cut out the damaged section, slide the coupling fully onto one side, position it over the joint, then press both ends. A coupling with a stop centers itself automatically but cannot be slid, so it only works when at least one pipe end is free to move.
3) Is the Viega 91290 made of 316 stainless steel, and where does that matter?
Yes, the body is 316 stainless steel, the more corrosion-resistant grade of the two common stainless types. That makes it the choice for stainless pipe systems and corrosive or washdown environments rather than a carbon steel fitting, which would create a dissimilar-metal joint. It is made in Germany.
4) What is Smart Connect on Viega MegaPress fittings and why does an inspector care?
Smart Connect is a feature of the sealing element that lets an unpressed connection leak intentionally during pressure testing. The point is that a joint someone forgot to press shows itself on the test instead of staying dry and failing later in a wall or ceiling. On a large press job it is the fastest way to find the one fitting that got missed.
5) What is the Viega MegaPress part number for the 1/2 inch stainless no-stop coupling?
Order model 91290. That is the Viega MegaPress 1/2 inch x 1/2 inch no-stop coupling in 316 stainless steel with Smart Connect.
