Viega 20623 ProPress 90° elbow Smart Connect technology Copper, 2-1/2'' x 2-1/2''

It takes 2-1/2 inch copper tube on both ends, sized 2-1/2 inch x 2-1/2 inch. It is a same-size elbow, not a reducing elbow, so both legs need to be 2-1/2 inch copper.

Yes, as long as the existing tube is 2-1/2 inch copper in sound condition. ProPress joins to the tube itself, not to the old fitting, so cut back to clean, round, undamaged pipe, deburr, and press. The elbow's P1 x P2 ends both go onto copper tube, so no adapter is needed to leave a soldered system.

Smart Connect is Viega's unpressed-connection feature: if a fitting gets left unpressed during a pressure test, it leaks at that joint so you find it before the walls close up. It does not change the install itself. You still cut the 2-1/2 inch copper square, deburr, mark insertion depth, and press with the correct 2-1/2 inch jaw or ring and actuator.

The body is copper, which is the standard ProPress material for copper tube systems and is used on potable water as well as hydronic and mechanical piping. Because it is copper to copper, there is no dissimilar metal junction where it ties into 2-1/2 inch copper mains.

Plan for more than the fitting body alone. The 20623 measures 6.472 inches in height and width with a 3.177 inch length, and the press ring and actuator need clearance to swing around the fitting once it is on the tube. In a tight chase or close to a wall, dry-fit the ring before committing to the layout.

The 20623 ProPress elbow is listed as made in the USA, which is what procurement officers on federal, municipal, and institutional work are usually looking to confirm. Match the part number 20623 on your submittal so the country of origin follows the fitting through the approval.

The 20623 weighs 2.101 lbs on its own. On a horizontal 2-1/2 inch copper run, put a hanger close to the elbow rather than letting the fitting hang between supports, since the elbow weight plus the water column concentrates load at the turn.
