Viega ProPress 2918 Copper Tee 3/4 x 1/2 x 3/4

SKU CH-ZSJ4-TXAAZ

Copper reducing tee with press-fit ends for 3/4, 1/2 and 3/4 inch tubes, rated to 200 psi

  • Reducing tee connects three pipe sizes in one fitting
  • Press-fit connections eliminate open-flame soldering on potable water lines
  • EPDM O-ring seals up to 200 psi operating pressure
  • Copper construction resists corrosion in water supply systems
  • Centre-stop dimple ensures correct insertion depth every time

Copper reducing tee for potable water

This Viega ProPress 2918 fitting joins three copper tubes in a reducing tee configuration. Side A and Side C accept 3/4 inch tube while Side B accepts 1/2 inch tube. All three connections use press-fit joints with factory-fitted EPDM O-rings. The centre stop dimple helps align each tube during assembly.

Rated for continuous pressure up to 200 psi

The copper body and EPDM seals are tested for sustained operation at 200 psi in potable water systems. Press-fit joints maintain their seal under constant load without the thermal cycling that can loosen threaded or soldered connections. No open flame is required, so the fitting can be installed in occupied buildings.

Press-tool installation with visual stop

A compatible press tool compresses each joint in seconds and the centre stop dimple gives a tactile reference for tube insertion depth. Common errors include skipping the deburring step, which can damage the O-ring, or pressing a joint twice, which may deform the fitting. Always verify the press indicator on the tool before moving to the next connection.

Questions about this item

Does the Viega ProPress 2918 tee generate noise, heat or draw power when the water runs all day?

No. It is a passive copper fitting with EPDM O-rings, so it adds no noise, heat or electrical load to the system.

What press tool and jaw size must I already own to install the 3/4 in and 1/2 in press-fit ends?

A compatible press tool with 3/4 in and 1/2 in jaws for copper ProPress fittings is required to crimp each connection.

Will the 200 psi rated tee work safely alongside older copper pipe and fittings already in the house?

Yes. The copper body and press-fit ends join directly to existing 3/4 in and 1/2 in copper tube, and the 200 psi rating matches typical residential pressure limits.
