Viega ProPress 2918 Copper Reducing Tee 1-1/4" x 1-1/4" x 3/4

SKU CH-70N6-1MR7S

Copper reducing tee with three press-fit connections for potable water systems, rated to 200 psi

  • Press-fit connections speed installation without soldering
  • EPDM O-ring seals potable water lines reliably
  • Copper construction resists corrosion for long service life
  • Reducing tee joins 1-1/4" and 3/4" lines in one fitting
  • Rated to 200 psi for high-pressure plumbing systems

Reducing Tee for Press-Fit Copper

The Viega ProPress 2918 is a copper reducing tee designed for potable water systems. It joins two 1-1/4 inch press-fit connections to a 3/4 inch branch using the ProPress crimp method. The fitting includes a rolled centre stop to control insertion depth on all three ports. Installers use it where a smaller branch line splits from a larger main.

Leak-Free Joints Under 200 psi

Each port uses an EPDM O-ring that seals when pressed with compatible tooling, eliminating open-flame soldering on site. The copper body handles a maximum operating pressure of 200 psi in normal service. No flux, solder or cooling time is required, so the joint is pressure-testable immediately after pressing. The pressed connection remains mechanically secure under thermal cycling.

Centre Stop and EPDM Seals Included

The rolled centre stop is built into the fitting body and ensures each tube reaches the correct depth without separate gauges. EPDM O-rings are factory-fitted for potable water compatibility and resist common disinfectants. No additional sealing compounds, gaskets or software are supplied or needed. The fitting is ready to press straight from the package.

Questions about this item

How do I press the 1-1/4" and 3/4" ends onto copper tube, and what step is often missed?

Use a ProPress tool with the correct jaw size for each tube diameter; the step often missed is fully inserting the tube until it contacts the rolled center stop inside each port before pressing.

Will the EPDM O-rings need replacement, and when?

EPDM O-rings are designed for the fitting's service life in potable water systems and do not have a scheduled replacement interval under normal conditions.

At what pressure does the 200 psi rating become the limiting factor during sustained use?

The 200 psi maximum operating pressure is the first limit reached; sustained pressure above this rating can compromise the press connection and O-ring seal.
