Viega ProPress 1" Extended Coupling w/o Stop - Double Press Connection - Smart Connect Technology

The Viega ProPress 1" Extended Coupling without Stop with Double Press Connection and Smart Connect Technology (MPN 79015) is a premium press-fit coupling engineered for modern hydronic and radiant heating systems where space constraints demand extended body clearance. This product is designed for professional installers and HVAC technicians who work with Viega's ProPress line, providing a reliable alternative to traditional threaded connections or solder joints.

The extended length of the coupling accommodates tight valve configurations and awkward pipe runs, ensuring that standard couplings do not interfere with shutoff valves or manifold bodies. Smart Connect Technology offers real-time feedback through audible and tactile confirmation when proper press pressure is applied, which helps to eliminate guesswork and reduce installation errors on job sites. The double press connection design creates a permanent, code-compliant seal rated for potable water and hydronic applications at full system pressure.

Contractors and mechanical engineers prefer this extended coupling for retrofit installations, radiant floor systems, and complex piping layouts where run distances or valve clearances matter. The 1" sizing connects standard copper tubing, and the absence of an internal stop allows for deeper insertion when routing pipes through tight spaces or when working with extended sleeve configurations common in floor heating and multi-zone systems.
