ProPress 2915 Copper Coupling 1 in

The Viega ProPress 2915 is a straight copper coupling with an integrated stop dimple, designed for potable-water systems. It connects two 1-inch copper tubes using press-fit ends and an EPDM O-ring seal. The fitting is rated for a maximum operating pressure of 200 psi.

Replaces soldered copper joints

This coupling eliminates the need for open-flame soldering, flux and cooling time on 1-inch copper pipe. The jump is worth it when fire permits are difficult, when working in tight cavities or when a fast, flameless connection reduces overall labour on potable-water installations.

Press-fit system constraints

The joint relies on a compatible press tool and correctly sized jaws to form a permanent, leak-free seal. Once pressed the connection cannot be disassembled or repositioned. Installers must verify that the tubing is clean, round and fully inserted to the centre stop before pressing.

Questions about this item

What copper tube size does the 1 in ProPress 2915 coupling accept on each end?

Both press-fit ends are sized for 1 in copper tube, so the same tube diameter fits either side.

Which tool and jaw are required to press this coupling, and what step is often missed?

Use a Viega ProPress tool with the correct 1 in jaw; the step often missed is fully seating the tube until it contacts the centre stop dimple before pressing.

When should the EPDM O-ring inside this coupling be inspected or replaced?

Inspect the EPDM O-ring whenever the system is depressurised for service; replace it if it shows cracking, hardening or permanent deformation.
