Viega 90320 – Frequently Asked Questions
1) Is the Viega MegaPress 90320 coupling a stop or no-stop coupling, and what does that change on the job?
The 90320 MegaPress coupling is a no-stop (slip) coupling, 1 inch by 1 inch. With no internal pipe stop, the fitting slides fully onto the pipe, so you can use it for repairs on a fixed run where you cannot spring the pipe apart, or to join two lengths without cutting extra. Because there is no stop registering insertion depth, you have to mark the insertion depth on both pipe ends yourself before pressing.
2) What pipe does the 1 inch Viega 90320 MegaPress coupling press onto?
It is a press coupling with two press ends (P1 x P2) sized 1 inch by 1 inch, so it joins two 1 inch pipe ends of the type MegaPress is made for. Both ends are press connections, so there is no thread and no solder joint anywhere on this fitting.
3) Is the Viega 90320 coupling stainless steel or carbon steel?
316 stainless steel throughout. That is the higher-chromium, molybdenum-bearing grade, which is what specifiers call out for corrosive or washdown environments rather than the carbon steel MegaPress fittings used on black iron gas and hydronic work. If your spec sheet says 316, this fitting meets it on material.
4) What does Smart Connect technology on the Viega MegaPress coupling actually do for the installer?
Smart Connect is Viega's unpressed-connection feature: before pressing, the sealing element is intentionally designed to leak when the system is pressure tested, so an unpressed joint shows itself during the test instead of after the walls close up. On a job with dozens of presses it is the fastest way to find the one you missed.
5) How much space do I need around the Viega 90320 press coupling to get a press tool jaw on it?
The coupling itself is 3.366 inches long with a 1.78 inch height and 1.78 inch width, and it weighs 0.502 lbs. Plan clearance beyond that body for the jaw of your press tool on each end, since a no-stop coupling is pressed twice, once per side. In a tight chase, measure the jaw swing against that 3.366 inch overall length before you commit.
6) Should I use a no-stop coupling or a standard coupling with a stop for my MegaPress repair?
Use the stopped coupling when you are building new and both pipe ends can be inserted to a fixed shoulder, it sets insertion depth for you and is harder to get wrong. Choose the no-stop version, like the 90320, when you are cutting into an existing fixed run and need to slide the fitting over one end to bridge the gap. The tradeoff is that you must mark insertion depth on both pipes yourself.
7) Where is the Viega 90320 MegaPress stainless coupling manufactured?
Made in Germany. For public and institutional procurement that tracks country of origin on submittals, that is the origin to record for the 90320.
8) What part number and barcode identify this 1 inch Viega MegaPress 316 stainless no-stop coupling?
Order it as Viega part number 90320. It is the 1 inch by 1 inch 316 stainless MegaPress coupling, no stop, with Smart Connect.
