Viega 25116 – Frequently Asked Questions
1) What are the two ends on the Viega 25116 MegaPressG adapter?
It is a press by male thread adapter, P x MPT, in 1-1/4 inch on both ends. The press end goes onto 1-1/4 inch carbon steel pipe and gets crimped with a MegaPress jaw; the male NPT end threads into a female-threaded valve, appliance connection, or existing threaded pipe. There is no second press end, so it is the transition point between pressed pipe and threaded components.
2) Can I use a MegaPressG fitting on a gas line, or is it for water?
MegaPressG is Viega's gas version of the MegaPress system, with the sealing element rated for gas service, which is why the G suffix exists on the 25116. Plain MegaPress fittings are the water and non-gas side of the same carbon steel system. Match the system to the service you are piping and do not mix the two.
3) Will the Viega 25116 press onto copper or stainless tube?
No. It is a carbon steel fitting and belongs on black iron or carbon steel pipe, which is what MegaPress presses. Copper needs a ProPress copper fitting and stainless needs a stainless press fitting; the sealing geometry and the jaw are not interchangeable with a carbon steel fitting.
4) What does Smart Connect on this Viega adapter actually do during install?
Smart Connect is a deliberate leak path in the sealing element that lets an unpressed connection weep under test pressure, so a joint you missed shows itself before the system is signed off. It does not replace pressing; it is there to catch the one fitting that got skipped on a long run.
5) Do I still need to use thread sealant on the threaded end of the 25116?
Yes. The press end is sealed by the fitting's own element once crimped, but the male NPT end is a conventional taper thread and needs an approved gas-rated sealant or tape on the threads. Only the press side benefits from the press seal.
6) What part number and manufacturer should I put on the submittal for this Viega adapter?
Order it as Viega MegaPressG 25116, 1-1/4 inch press x 1-1/4 inch MPT, carbon steel. It is made in Germany. That model number is the whole identity of the part, there are no size or finish choices behind it.
