Viega 79005 ProPress extended coupling 1/2" x 1/2" trap

SKU CH-P9PD-VKVJS MPN 79005

A press-fit copper coupling joins two 1/2-inch lines without a centre stop for a straight, extended run rated to 200 psi

  • TypeDrain Components
  • MaterialHAWA
  • Extended coupling provides 3 in reach for tight copper joints
  • Press-fit ends install without solder for fast potable-water connections
  • EPDM O-ring seals up to 200 psi operating pressure
  • Copper construction resists corrosion in plumbing systems
  • No centre stop allows continuous pipe runs through the fitting

Viega ProPress Extended Coupling 1/2

The Viega 79005 ProPress extended coupling joins two 1/2-inch copper tubes in potable-water systems. Its straight, extended body provides extra reach for tight installations. The fitting uses press-fit connections on both ends, eliminating the need for soldering or threading. Supplied new, it is ready for professional plumbing work.

Capacity and headroom: 200 psi operating pressure

Rated for a maximum operating pressure of 200 psi, the coupling handles typical residential and commercial water-supply demands. The EPDM O-ring seals reliably under normal pressure cycles. The design includes no centre stop, allowing full insertion depth when required. It is not suited for applications exceeding the stated pressure rating.

Press-fit copper with no centre stop

The specific fitting shape is a straight extended coupling made from copper with EPDM O-ring material. Both connection types are press-fit for 1/2-inch copper tube size, and the overall length measures 3 in. The absence of a centre stop distinguishes this model from standard couplings. Verify that press-tool compatibility and the no-stop design match your installation requirements.

Questions about this item

Will this ProPress 79005 extended coupling press onto my existing 1/2" copper lines without soldering?

Yes, both ends use a 1/2" press-fit connection for copper tube, so you can join existing lines with a ProPress tool instead of soldering.

How can I confirm the joint is watertight after pressing the 79005 coupling?

Pressurise the system up to 200 psi and inspect each press joint for leaks; the EPDM O-rings seal on contact when pressed correctly.

Does the 79005 box include the press jaws or any pipe, or just the fitting?

Only the copper extended coupling with EPDM O-rings is included; press jaws and copper tube must be purchased separately.
