Viega 78102 ProPress reducer Smart Connect technology Copper, 1-1/2'' x 1''

FTG x P describes the two ends. The 1-1/2 inch end is a fitting-end (FTG), sized like copper tube so it inserts into another 1-1/2 inch press fitting or socket, and the 1 inch end is a press socket (P) that receives 1 inch copper tube. So it goes fitting-to-fitting on the large side, tube-to-socket on the small side. If you need a socket on both ends, this is not the right reducer.

Yes. The 78102 is a copper press reducer sized 1-1/2 inch by 1 inch, so the 1 inch press socket takes standard 1 inch rigid copper tube and the 1-1/2 inch fitting end slips into a 1-1/2 inch press socket. It is copper body material, so it is for copper tube systems, not PEX or steel.

That is exactly what it does, with one condition: the 1-1/2 inch side is a fitting end, so it has to land inside a 1-1/2 inch press socket, coupling, tee or elbow. It will not slip over 1-1/2 inch tube. If your 1-1/2 inch run is open tube, you need a reducer with a 1-1/2 inch press socket (P x P) instead.

Yes, this is a press-connect fitting, not solder or thread, so it needs a press tool with the correct jaw or ring for each size. The 1-1/2 inch end uses a 1-1/2 inch actuator/ring setup and the 1 inch end uses a 1 inch jaw. No flame, no flux, but the tool and both jaw sizes have to be on the truck before you open the wall.

Smart Connect is Viega's feature that makes an unpressed joint leak visibly during pressure testing instead of holding and failing later. On a run with a 1-1/2 to 1 inch reducer buried behind drywall, that is how you catch a missed crimp before closing up.

Order Viega model 78102. That is the manufacturer part number for the 1-1/2 inch by 1 inch copper ProPress reducer with an FTG large end and a press socket small end.

Copper body, made in Germany. Copper press fittings are the standard match for copper potable and hydronic tube; bronze bodies are generally used where a fitting transitions to threads or valves.
