Viega 78167 – Frequently Asked Questions
1) What sizes does the Viega 78167 ProPress reducer connect?
The Viega 78167 is a copper press reducer that takes 2 inch copper tube on the large end and 1-1/2 inch on the small end. Both ends are press connections (P1 x P2), so it goes between two lengths of copper tube, not onto threads.
2) Can I use the Viega 78167 reducer on PEX or threaded pipe?
No. Both ends of the 78167 are press ends (P1 x P2) sized for copper tube, 2 inch and 1-1/2 inch. For a threaded transition you need a press x male or female adapter, and for PEX you need a PEX press fitting. This one only joins copper to copper.
3) Do I need a different press jaw for each end of a 2 inch by 1-1/2 inch ProPress reducer?
Yes. Each press end is crimped separately, so you press the 2 inch end with a 2 inch jaw or ring and the 1-1/2 inch end with a 1-1/2 inch jaw or ring. On 2 inch copper that normally means the press ring and actuator rather than a standard jaw set. Order the tooling for both sizes before you get to the joint.
4) What does Smart Connect mean on this Viega reducer?
Smart Connect is Viega's feature that intentionally leaks a small amount at an unpressed connection during pressure testing, so an installer can spot a joint that was missed before the system is buttoned up. It is built into the 78167 reducer, not an option you add.
5) How much room do I need to fit the 78167 reducer between fittings?
The 78167 measures 2.594 inches in height and length with a 3.748 inch width, so plan on roughly that much clear space at the transition plus enough straight tube either side for the press tool head to swing. It weighs 0.635 lbs, so it needs no separate support beyond normal tube hangers.
6) What part number and UPC should I order for the Viega 2 inch to 1-1/2 inch press reducer?
Order Viega part 78167. The UPC on the package is 691514781679. It is made in Germany, and the same number covers the 2 inch x 1-1/2 inch copper press reducer with Smart Connect.
