Viega 79355 – Frequently Asked Questions
1) What size press and thread does the Viega 79355 ProPress adapter connect?
The Viega 79355 is a 1-1/4 inch press by 1-1/2 inch female thread adapter. Connection type is P x FPT, so the press end slips over 1-1/4 inch copper tube and the other end threads onto a 1-1/2 inch male NPT nipple, valve tailpiece, or equipment connection. It is a size-increasing adapter, not a straight 1-1/4 to 1-1/4 fitting.
2) Can I use the Viega 79355 adapter on potable drinking water lines?
Yes. The 79355 adapter is zero lead bronze, which is what potable water systems call for. The same fitting works on hydronic and mechanical copper systems as well, since the material and the press connection do not change with the application.
3) What does Smart Connect mean on this Viega press adapter, and do I still have to press every joint?
Smart Connect is Viega's feature that lets water or air escape past an unpressed connection during testing, so an unpressed joint shows itself before the system is closed up. It does not make the joint permanent on its own. Every 79355 press end still has to be pressed with the correct 1-1/4 inch ProPress jaw or ring before the system goes into service.
4) Do I need pipe dope or tape on the threaded side of the 79355?
The FPT side is a standard tapered female pipe thread, so it gets sealed the normal way with thread sealant or PTFE tape on the male thread. Nothing is applied to the press side. Make the threaded joint first where you can, then press, so wrenching does not twist a finished press connection.
5) Where is the Viega 79355 ProPress adapter made, and what part number do I order?
It is made in Germany and ordered as Viega part 79355, a zero lead bronze 1-1/4 inch press by 1-1/2 inch FPT adapter. That MPN is what distributors and spec writers use to keep the whole job on one fitting family.
6) Is bronze the right choice here, or should I be looking at a copper press adapter?
Bronze is the standard body material for press fittings that carry a pipe thread, because the threads need the strength that a formed copper fitting does not give. The 79355 is zero lead bronze on both ends of the casting, so it suits potable service and stands up to wrenching on the 1-1/2 inch FPT side. Copper press fittings are for press-to-press transitions, not threaded ones.
