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

The Viega ProPress 1" Extended Coupling without Stop featuring Double Press Connection and Smart Connect Technology is a press-fit copper coupling designed for professional plumbing and HVAC installations using ASTM B88 copper tubing. This extended coupling eliminates the need for traditional soldering or threading, delivering fast, reliable connections in tight spaces where standard couplings won't fit.

Built from copper with EPDM sealing elements, the coupling provides corrosion resistance and durability in both residential and commercial applications. The Smart Connect Technology ensures consistent, code-compliant press connections without the guesswork—critical for pass-through inspections and long-term system integrity. The extended body accommodates installations where space constraints or pipe configuration demand extra clearance, making it indispensable for retrofit work, renovation projects, and complex piping layouts where standard couplings create interference.

Professionals specify Viega ProPress systems for speed and reliability on high-volume jobs. The press connection technology eliminates flux, solder, and open flame—reducing fire risk on jobsites, speeding installation time, and allowing work in occupied buildings or sensitive environments. The 1" size addresses mid-range distribution lines common in residential whole-home upgrades and light commercial systems. No soldering experience required, and connections are immediately pressure-testable.

Compatible with standard Viega press tools and approved for use in potable water, heating, and cooling systems. The 79015 part number identifies this specific extended coupling geometry—verify compatibility with your press tool and local plumbing codes before ordering.
