Viega ProPress 2" Extended Coupling

The Viega 79030 is a straight extended coupling designed for potable water systems. It connects two 2-inch copper tubes using press-fit connections on both ends. The fitting is manufactured from copper with an EPDM O-ring seal. It carries no centre stop, allowing full pipe insertion depth.

Verify copper tube size and press tool access

Confirm that both pipe runs use 2-inch copper tubing sized to the standard copper tube size dimension. Ensure your press tool and jaw set are rated for 2-inch ProPress fittings before starting the installation. The 5 5/16-inch overall length requires adequate linear clearance between the two pipe ends. No centre stop means pipes can slide fully into the fitting.

Rated for 200 psi sustained pressure

The coupling is rated to a maximum operating pressure of 200 psi for continuous service. Copper construction and the EPDM seal maintain joint integrity under constant system pressure without degradation. The press-fit connection resists separation under sustained load cycles. No stop design does not affect the pressure rating or long-term sealing performance.
