Viega ProPress 1-1/4" Extended Coupling w/o Stop - Double Press Connection - Smart Connect Technology

The Viega ProPress 1-1/4" Extended Coupling without Stop featuring Double Press Connection and Smart Connect Technology is a copper press fitting designed for seamless, reliable connections in potable water and hydronic heating systems. This coupling combines the speed of press technology with Viega's proven Smart Connect system, eliminating the need for solder, flux, or torches while delivering superior joint integrity on ASTM B88 copper tubing.

The extended coupling design provides additional working room in confined spaces and tight installations where standard couplings would be impractical. Manufactured from high-grade copper with EPDM sealing elements, this fitting withstands typical system pressures and temperature cycling without degradation. The press-connection method—executed with a dedicated hydraulic or mechanical press tool—creates a permanent, leak-proof seal that requires no rework or re-pressing, delivering confidence in retrofit and new construction applications alike.

This product serves mechanical contractors, plumbing professionals, and facilities managers who demand faster installation cycles without sacrificing quality. The 1-1/4" size accommodates mid-sized distribution lines in residential multi-unit buildings, small commercial systems, and radiant heating networks. The extended coupling variant is particularly valuable in retrofit scenarios, renovation work, and installations where pipe runs require flexible routing through existing structural elements.

Viega's ProPress system has become the industry standard in press-fit copper technology, recognized across North America for consistency and reliability. Specifying this coupling ensures compatibility with existing ProPress tooling and accessories, reducing inventory complexity on job sites and across contractor fleets.
