Viega 20798 ProPress XL reducing tee 3" x 3" x 1-1/2

SKU CH-74CE-2DQHP

Copper reducing tee joins three press-fit lines at 3 in, 3 in and 1-1/2 in with a 200 psi rating

  • Reduces 3 in line to 1-1/2 in branch
  • Three press-fit connections install without soldering
  • EPDM O-ring seals potable water at 200 psi
  • Copper body with centre-stop dimple ensures correct insertion
  • 6 19/32 in overall length fits tight spaces

ProPress XL Reducing Tee 3" x 3" x 1-1/2

This copper crimp tee fitting joins three press-fit connections in a single junction. Two 3-inch ports and one 1-1/2-inch port allow a direct reduction without extra couplings. It is intended for potable water systems and rated for 200 psi maximum operating pressure. The EPDM O-ring material resists common water treatment chemicals.

Center Stop Dimple and EPDM O-Ring

The built-in center stop dimple sets insertion depth automatically so installers cannot push the tube too far. EPDM O-rings ship pre-lubricated in each port, removing the need for separate sealant or flux. Both features reduce the number of loose parts on site and speed up repetitive connections.

Press-Fit Installation and Common Pitfalls

A compatible ProPress tool and correctly sized jaws are required; hand tools or mismatched jaws will not produce a sealed joint. Deburr and clean each tube end before pressing to prevent O-ring damage. The overall length of 6 19/32 in fixes the layout, so measure the run accurately before cutting pipe.

Questions about this item

How often should the EPDM O-rings on the 3" x 3" x 1-1/2" ProPress XL reducing tee be inspected or replaced?

EPDM O-rings are designed for the service life of the fitting; inspect them visually whenever the system is drained or modified, and replace only if cuts, hardening or permanent deformation are found.

At what pressure does the 200 psi maximum operating pressure limit become the governing factor during sustained use?

The 200 psi rating is the ceiling for continuous operation; sustained pressure above that value will exceed the fitting's design limit before any other mechanical constraint is reached.

How much heat does the copper body of this 6 19/32 in reducing tee add to the water when the system runs all day?

Copper conducts heat rapidly, so the tee will reach water temperature quickly and adds no measurable heat of its own during continuous operation.
