Viega 16108 – Frequently Asked Questions
1) What size copper pipe does the Viega ProPressG 16108 coupling fit?
The ProPressG coupling model 16108 is a 1 inch by 1 inch fitting, so it joins two runs of 1 inch copper tube. Both ends are press connections (P1 x P2), not sweat or threaded, so the tube ends go in dry and get crimped with a press tool and the matching 1 inch jaw.
2) What is the difference between a ProPressG coupling with stop and one without a stop?
A coupling with a stop, like the 16108, has a formed ridge in the middle of the body that the tube butts against, so each pipe end seats to a fixed insertion depth. That is what you want on a normal joint between two cut lengths. A stopless (no-stop) coupling leaves the bore clear so it can slide fully onto one pipe and then back over the joint, which is how you repair a section in the middle of an installed line you cannot pull apart. If you are cutting out a bad length and springing the pipe back together, order the stopless version instead.
3) Can I use a ProPressG coupling on gas lines, or is it only for water?
ProPressG is Viega's gas-rated press system, and it is identified by the yellow sealing element rather than the black EPDM used on the water-side ProPress fittings. Do not mix the two: a standard ProPress coupling is not a substitute for the 16108 on a fuel gas line, and the ProPressG fitting is not intended as a drop-in for potable water work. Match the fitting family to the service.
4) Do I need a special tool to install the Viega ProPressG 16108, or can I solder it?
This is a press-only fitting. Both ends are press sockets, so it needs a press tool with a 1 inch jaw sized for the Viega press profile. There is nothing to solder, thread, or solvent weld. Plan on deburring and marking insertion depth on the tube before pressing.
5) Is the Viega 16108 coupling copper or bronze, and where is it made?
It is a copper-body press coupling made in Germany. Copper body means it is intended for copper tube systems, so you are not introducing a dissimilar metal at the joint the way a brass or bronze adapter would.
6) Is this Viega press coupling approved for commercial jobs or just residential?
Both. The 16108 is carried for commercial and residential applications, so the same 1 inch coupling works on a multi-family or light commercial riser and on a single family house. For a facility standardizing on one press system, that means one fitting number covers both sides of the portfolio.
7) What is the part number and UPC for the 1 inch Viega ProPressG coupling with stop?
Order it as Viega part 16108, UPC 691514161082. That single number covers the 1 inch by 1 inch ProPressG coupling with stop; there are no finish or configuration options to specify with it.
