Viega 20683 ProPress tee Smart Connect technology Copper, 2-1/2'' x 2-1/2'' x 2-1/2''

Straight, all three ports the same. The 20683 is a 2-1/2 inch x 2-1/2 inch x 2-1/2 inch copper ProPress tee, so the run and the branch all take 2-1/2 inch copper tube. If you need to drop the branch down to a smaller size, you want a reducing tee, not this one.

Smart Connect is the feature that makes an unpressed joint leak on purpose during test. Fill and pressurize the system and any 20683 tee you missed will weep at the sealing element instead of holding tight and failing later. On a 2-1/2 inch main with dozens of joints, that is how you find the one connection the crew walked past before the ceiling closes up.

Not with the same jaws. At 2-1/2 inch ProPress moves to press rings with an actuator rather than a standard jaw set, so budget for the 2-1/2 inch ring and the matching adapter on your press tool before the 20683 goes in. Crews that own only the small jaw set get stopped at this size on the job.

Yes, provided you can cut a clean section out and get the tube prepped. Since all three ports of the 20683 are press, the existing sweat main just needs to be cut square, deburred, and the OD cleaned of solder splatter and scale for the full insertion depth. Mark your insertion depth on each tube before you press, a fitting that is not fully bottomed is the most common failure on retrofit work.

It is a copper press tee for plumbing use, and copper ProPress with the standard sealing element is the common choice for domestic water distribution as well as hydronic heating and chilled water. What decides it for any specific system is the sealing element, so match the seal to the medium, fuel gas and oxygen lines take their own dedicated fittings and are not interchangeable with a standard water press tee.
