Viega 25960 MegaPress reducer Smart Connect technology Carbon steel, 2'' x 1-1/4''

The 25960 MegaPress reducing tee is a 2 inch x 1-1/4 inch fitting, so the run is 2 inch and the reduced opening is 1-1/4 inch. Viega lists it as model 4815.2. All ends are press connections (P1 x P2), not threaded or welded.

It's a carbon steel MegaPress fitting, which is the material family Viega makes for pressing onto black iron and carbon steel pipe rather than copper. Keep the carbon steel line carbon steel end to end; for a copper system you want a copper press fitting instead, not this one.

No cutting oil, no threading, no hot work. The 25960 is a press tee (P1 x P2 connections), so you cut the pipe, deburr, mark depth, and press. That's why it gets specified for occupied buildings and mechanical rooms where a hot work permit is a problem.

Plan on 5.268 inches of length along the run and 2.894 inches in both height and width for the branch side of the fitting. Add clearance beyond that for the press tool jaw to swing around each joint, which is usually what decides whether a tight rack of pipe is workable.

Smart Connect is Viega's feature that lets an unpressed connection be identified during pressure testing, so a joint you missed shows itself instead of failing later behind a wall. On a large carbon steel branch run with dozens of presses, that's the inspection shortcut. It does not replace pressing; every joint still has to be pressed with the correct jaw.

A single 2 x 1-1/4 inch reducing tee gives you one less joint to press and one less leak path than a 2 inch tee plus a reducer, and it takes up less of your 5.268 inch run length. Use the full-size tee with a separate reducer only when you need the branch to stay 2 inch for a future tie-in.

Made in Germany. For public and institutional work where country of origin has to be documented on the submittal, that's the value to carry through, along with the carbon steel material callout.
