Viega 16118 – Frequently Asked Questions
1) What size pipe does the Viega ProPressG coupling 16118 fit?
The 16118 ProPressG coupling is a 1-1/2 inch by 1-1/2 inch fitting, so it joins two 1-1/2 inch copper tube ends. Both ends are press connections (P1 x P2), not solder or thread, so the tube has to be cut square, deburred, and marked to depth before pressing.
2) What is the difference between a press coupling with a stop and one without?
A coupling with a stop, like the Viega 16118, has an internal shoulder in the middle of the body. Each tube end butts against that shoulder, which sets insertion depth for you and keeps the joint from sliding. A stopless (slip) coupling has no shoulder, so tube can pass all the way through, which is what you want for repair work where you cannot pull the pipe apart. For a straight new-run joint of two 1-1/2 inch copper tubes, the stop version is the normal choice.
3) Can I use a ProPressG coupling on a gas line?
ProPressG is Viega's gas-rated press system, which is a different seal element from the standard ProPress line used for water. The 16118 is a ProPressG coupling in 1-1/2 inch copper, so it belongs on gas piping runs built with ProPressG fittings and pressed with the matching jaw. Do not mix it into a potable water job as a substitute for standard ProPress.
4) Is the Viega 16118 coupling copper or bronze?
Copper. The 16118 is a copper-bodied press coupling, so it is a like-metal joint on copper tube with no dissimilar-metal transition to worry about.
5) Do I need any solder or flux with the Viega 16118?
No. It is a press-connect coupling on both ends (P1 x P2), so the joint is made cold with a press tool and the correct 1-1/2 inch jaw or ring. No torch, solder, flux, or threading, which is why it gets specified in occupied buildings where hot work permits are a problem. You will still need a tube cutter and deburring tool.
6) What is the Viega part number I should order for a 1-1/2 inch ProPressG coupling with stop?
Order Viega model 16118. That is the manufacturer part number for the 1-1/2 inch by 1-1/2 inch ProPressG copper coupling with stop, and it is sold as a single model with no finish or size options to specify.
7) Is this coupling approved for commercial work or just residential?
Both. Viega lists the 16118 ProPressG coupling for commercial and residential applications, so the same part covers multi-family, light commercial, and single-family gas piping in 1-1/2 inch copper.
