Viega 15608 ProPress reducer Smart Connect technology Copper, 2'' x 1''

The Viega 15608 is a 2 inch by 1 inch copper reducer, so it takes a 2 inch copper run down to a 1 inch branch or continuation. Both ends are press connections (P1 x P2), meaning copper tube slips into the fitting and is crimped with a press tool rather than soldered.

No torch needed. Both ends of the 15608 are ProPress press connections, so the joint is made cold with a press tool and the correct 2 inch and 1 inch jaws or rings. That is the main reason crews use it on occupied buildings where hot work permits are a problem.

Yes, as long as the tube is copper at 2 inch and 1 inch nominal sizes. The fitting body itself is copper, so it is a like-metal joint with copper tube and there is no dissimilar metal concern the way there would be with a bronze or steel transition. Make sure the tube ends are cut square, deburred, and marked to full insertion depth before pressing.

No. This is a copper press reducer with copper press sockets on both ends, sized for 2 inch and 1 inch copper tube. PEX needs a PEX press system, and steel needs the stainless or carbon steel press line. Pairing a copper fitting to the wrong tube material will not seal and is not a listed connection.

Smart Connect is Viega's unpressed-connection feature: a joint that was assembled but never pressed will leak visibly during pressure testing, so the installer finds it on test instead of after the walls close. On a large job with a lot of 2 inch mains, that is the difference between one missed crimp costing an hour and costing a ceiling.

A single 2 inch x 1 inch reducer makes one transition with two press joints. Stacking a coupling and bushing adds joints, adds leak paths, and adds press cycles on the crew's clock. Where the size change is straight 2 inch to 1 inch copper, the one-piece reducer is the cleaner call. Use separate fittings only when you also need to change direction or branch off.

The reducer ships as a complete fitting with the sealing element already in the press socket. What you supply is the press tool and the jaws or rings sized for 2 inch and 1 inch copper, plus a cutter, deburring tool, and a depth marker. There is no separate gasket, solder, or flux to buy.

Made in Germany. Worth knowing for spec packages and government or institutional jobs where country of origin has to be recorded in the submittal.

Each 15608 reducer weighs 0.583 lbs, so a carton of them adds up fast on a big riser package but a single fitting is easy to carry up a ladder. Useful number when you are pricing freight on a bulk copper press order.
