Viega 23278 – Frequently Asked Questions
1) What size does the Viega ProPressG reducer 23278 take on each end?
It reduces 1 inch down to 1/2 inch, with a press connection on both ends (P1 x P2). So you press it onto 1 inch copper tube on the large side and 1/2 inch copper on the small side. No threads on either end.
2) Is the ProPressG 23278 reducer a gas fitting or can I use it on water lines?
The 23278 is a ProPressG reducer, Viega's gas line system. The ProPressG sealing element is the yellow HNBR type for fuel gas service, which is why it is catalogued as a gas fitting rather than a potable water fitting. Use ProPress (not G) fittings for water.
3) What material is the Viega 23278 reducer made from, and does that matter for a gas install?
Copper. That means it is intended for copper tube gas piping, pressed with a ProPressG jaw, not for black iron or CSST runs. Mixing it onto steel pipe needs a transition fitting, which this is not.
4) Do I need a special press jaw for the 1 inch end of this Viega reducer?
Yes, two different jaw sizes. The large end is 1 inch and the small end is 1/2 inch, so your press tool needs a jaw or ring for each size. Half inch through 1 inch are standard jaw sizes on most ProPress-compatible tools, but you cannot press a 1 inch socket with a 1/2 inch jaw.
5) Can I use the ProPressG 1 inch x 1/2 inch reducer on a commercial job, or is it residential only?
Both. The 23278 reducer is rated by Viega for commercial and residential applications, so it is the same part whether you are reducing a gas branch in a single family home or in a multi-family or commercial building.
6) What is the Viega part number for the 1 inch x 1/2 inch ProPressG copper reducer?
Viega model 23278. That is the manufacturer part number to quote, and it covers the copper ProPressG reducer in 1 inch by 1/2 inch.
7) Where is the Viega 23278 ProPressG reducer made?
Germany. Viega manufactures it there, which matters on spec jobs where country of origin has to be documented in the submittal package.
