Viega 98310 – Frequently Asked Questions
1) What kind of connection does the Viega 98310 MegaPress adapter have on each end?
The Viega 98310 is a press-to-male-thread adapter: one end is a MegaPress press connection, the other is male pipe thread (P x MPT). So you press onto the pipe on one side and thread into a female-threaded fitting, valve, or piece of equipment on the other.
2) What size pipe does the Viega 98310 adapter fit?
It is the 4 inch by 4 inch size: 4 inch press end to 4 inch male pipe thread. It will not adapt down to a smaller thread, so if you need 4 inch pipe to a smaller threaded connection you want a reducing arrangement rather than this part.
3) Is the Viega 98310 MegaPress adapter stainless or carbon steel?
It is 316 stainless steel, body and all. That is the alloy you want where the line or the surrounding environment is corrosive, and it is why this one gets specified over a carbon steel MegaPress fitting on chemical, washdown, or coastal mechanical room work.
4) Does the Viega 98310 MegaPress fitting have the leak-detection feature for unpressed joints?
Yes. The 98310 carries Viega's Smart Connect feature, which leaves an unpressed connection intentionally leaking during pressure test so an installer can find the joint that was missed before the system is put into service.
5) Do I need thread sealant on the MPT end of a MegaPress adapter, or is the press seal enough?
Two different joints, two different methods. The press end seals on the sealing element when the jaw crimps it, with no dope or tape involved. The male pipe thread end is a conventional tapered thread joint and still needs an appropriate thread sealant or PTFE tape rated for the service fluid and temperature.
6) Where is the Viega 98310 MegaPress adapter manufactured?
Made in Germany. That matters on public and institutional jobs where country of origin has to be documented on the submittal.
