Viega 91315 – Frequently Asked Questions
1) What size pipe does the Viega MegaPress 91315 press onto?
The 91315 is a 2 inch by 2 inch fitting, so both press ends take 2 inch pipe. It is not a reducing fitting, both sides are the same size.
2) What does "no stop" mean on a MegaPress coupling, and when would I use one?
A no-stop coupling has no internal shoulder, so it slides freely along the pipe. That is what you want for a repair or a tie-in where the pipe cannot be pulled apart: cut out the bad section, slide the coupling fully onto one end, bring the pipes together, then center it and press both ends. A standard stop coupling can't do that because the shoulder blocks it. Viega 91315 is the 2 inch by 2 inch no-stop version. Because there is no stop to register against, mark your insertion depth on the pipe before you press so the coupling ends up centered on the joint.
3) Is the Viega 91315 stainless or carbon steel, and can I use it on a corrosive or outdoor line?
It is 316 stainless steel. 316 is the molybdenum-bearing grade used where chlorides and wash-down or coastal exposure are a concern, which is why it gets specified for stainless pipe systems rather than the carbon steel version. Keep the fitting metal matched to the pipe metal: use this on stainless pipe, not as a mixed-metal patch on black iron.
4) Is the Viega 91315 a two-end coupling or a three-way fitting?
Two ends. The connection type is P1 x P2, meaning one press end to one press end, straight through at 2 inch. If you need a branch off the run, a coupling is not the part, you want a MegaPress tee.
5) What is Smart Connect on this Viega fitting and why does it matter on an inspection?
Smart Connect is Viega's unpressed-connection feature: the sealing element is shaped so an unpressed joint leaks a controlled amount during pressure test instead of holding. On a 2 inch line with a lot of joints, that is how you find the one connection the crew missed before the ceiling closes up. The 91315 coupling includes it on both press ends.
6) Do I need a special press tool jaw for a 2 inch MegaPress fitting?
Yes. Two inch is outside the range of standard compact jaws, so it takes a press tool with the larger actuator and the 2 inch MegaPress ring and adapter set rather than a jaw. Plan the tooling before you order the fitting, since the 91315 is a 2 inch by 2 inch press connection on both ends and cannot be soldered or threaded as a fallback.
7) How much room do I need around the pipe to fit and press the Viega 91315?
The fitting body measures 4.819 inches long by 2.894 inches across, and it weighs 1.256 lbs. Allow for that plus the swing of the press ring, so tight joist bays or a fitting hard against a wall are the places to check before you commit. A no-stop coupling also needs axial room to slide onto the pipe before you center it.
8) What is the exact part number to order for the 2 inch 316 stainless no-stop MegaPress coupling?
Viega part number 91315. That number covers the 2 inch by 2 inch no-stop coupling in 316 stainless with Smart Connect, and it is the only configuration that number refers to, so there is no size or finish option to specify alongside it.
9) Where is the Viega 91315 MegaPress fitting made?
Germany. Useful if you are filling out submittals or a country-of-origin line on an institutional purchase order.
