Viega 16123 – Frequently Asked Questions
1) What size pipe does the Viega ProPressG coupling 16123 fit?
It's a 2 inch by 2 inch coupling, so both ends press onto 2 inch copper tube. Connection type is press on both ends (P1 x P2), meaning there is no threaded or soldered end anywhere on the fitting.
2) What does "with stop" mean on a ProPressG coupling, and when would I want one without?
The stop is an internal ridge in the middle of the coupling that the tube butts against, so each pipe end seats to a fixed insertion depth. That's what you want on a normal joint because it sets the engagement for you. A coupling without a stop lets tube slide straight through, which is what you use for repairs or when you need to slip the coupling back over an existing run you can't spread apart. Model 16123 is the version with the stop.
3) Is the Viega 16123 coupling for gas or for water?
ProPressG is Viega's gas line press system, and the 16123 is a ProPressG fitting. The sealing element in ProPressG fittings is the gas-rated one, which is what distinguishes it from standard ProPress used on potable water and hydronics. Don't mix ProPressG and ProPress fittings on the same gas run.
4) What is the Viega 16123 coupling made of, and can I press it onto hard drawn copper tube?
The body is copper, so it presses onto copper tube. It is not a bronze or stainless fitting and it is not intended for steel or CSST gas pipe.
5) Do I need a special tool head for a 2 inch Viega press coupling?
Yes. At 2 inch you're above the range of the compact press tools and their jaws. A 2 inch copper press joint takes a full size press tool with the 2 inch ring and an actuator adapter rather than a standard jaw. Nothing about the fitting changes that, it's purely a function of the 2 inch by 2 inch size.
6) What part number do I order for a 2 inch Viega ProPressG coupling with stop?
Order Viega part number 16123. That's the manufacturer number for the 2 inch by 2 inch ProPressG coupling with stop, copper body.
7) Can I use a 2 inch ProPressG coupling on a commercial job, or is it residential only?
Both. The 16123 is listed for commercial and residential applications, so it's the same fitting whether you're running fuel gas in a multi-family building or a single-family house.
8) Where is the Viega ProPressG coupling manufactured?
Made in Germany. That matters on spec jobs where country of origin has to be documented for the submittal package.
