Viega 90310 – Frequently Asked Questions
1) Is the Viega MegaPress 90310 a 1/2 inch coupling, and what does the "no stop" mean for repair work?
The Viega MegaPress 90310 is a 1/2 inch by 1/2 inch press coupling with no internal tube stop. Without the stop, the coupling slides freely along the pipe, so you can position it over a cut section and repair an existing run in place rather than having to spring the pipe apart to butt it against a stop. Both ends are press connections (P1 x P2).
2) Is the 90310 a coupling or a tee? I need to know which part I'm ordering.
It is a two-end coupling, 1/2 inch on both sides, joining two lengths of pipe in a straight run. It has no branch outlet, so if you need to take a 1/2 inch branch off a main you need a MegaPress tee instead.
3) Can I use the 90310 coupling as a slip repair on an existing 1/2 inch line without cutting the pipe out?
That is what the no-stop design is for. Because there is no internal shoulder, the coupling slides along the pipe, letting you bridge a cut or damaged section in a fixed run and then press both ends. A coupling with a stop would need the pipe ends pulled apart to seat. Mark your insertion depth on both sides before pressing, since the stop will not set it for you.
4) What is the 90310 MegaPress coupling made of, and can it be used on a corrosive or wet service line?
The body is 316 stainless steel, the grade specified where chloride exposure and corrosion resistance matter more than standard 304. That makes it the material choice for lines where carbon steel or plain stainless would pit. It is made in Germany.
5) How much room do I need to fit the Viega 90310 coupling in a tight joist bay or wall cavity?
The coupling measures 2.776 inches long with a 1.264 inch height and 1.264 inch width, and weighs 0.224 lbs. Allow for the press tool jaw around it as well, since the jaw needs clearance on all sides of the fitting to close fully.
6) What does Smart Connect technology do on a MegaPress fitting?
Smart Connect is Viega's unpressed-connection feature: an unpressed fitting deliberately leaks during pressure testing so the installer can find the joint they missed before the system is buttoned up and the ceiling closed. It does not change the pressed joint, only how you catch a skipped press. The 90310 coupling includes it.
