Viega ProPress 1" - 45° Copper Elbow - Double Press Connection - Smart Connect Technology

The Viega ProPress 1" – 45° Copper Elbow with Double Press Connection and Smart Connect Technology is a precision plumbing fitting engineered for reliable press-fit installation on ASTM B88 copper tubing systems. This fitting provides a compact 45-degree directional change in 1-inch copper lines, making it essential for navigating spatial constraints in residential, commercial, and industrial piping layouts where standard 90-degree configurations won't fit.

The press-fit connection method eliminates the need for solder, flux, or open flames, significantly reducing installation time and safety risks on job sites. The double press connection design ensures secure sealing at both ends of the elbow, with EPDM sealing elements providing reliable performance across standard pressure and temperature applications. Smart Connect Technology enables visual and tactile feedback during installation, confirming proper engagement without requiring specialized diagnostic equipment. The copper construction delivers corrosion resistance in both potable water and hydronic heating/cooling systems.

This fitting serves HVAC technicians, plumbers, and maintenance professionals who prioritize fast, code-compliant installations. It's particularly valuable in retrofit applications, confined spaces, and environments where flame-free operation is required. The 45-degree angle handles direction changes more gradually than 90-degree elbows, reducing turbulence and pressure loss in circulation systems—a meaningful advantage in long hydronic runs or complex piping networks where flow optimization affects overall system efficiency.

Viega's press-fit system is widely recognized in professional plumbing and mechanical contracting as a faster, safer alternative to traditional soldered connections. The Viega ProPress 1" 45° Copper Elbow (MPN 77028) integrates seamlessly into existing press-fit copper piping systems, ensuring compatibility with standard Viega presses and other compliant press tools.
