Viega ProPress 2-1/2" - 45° Copper Elbow - Double Press Connection - Smart Connect Technology

The Viega ProPress 2-1/2" 45° Copper Elbow with Double Press Connection and Smart Connect Technology is a precision plumbing fitting designed for reliable, permanent connections in both residential and commercial piping systems. This copper elbow delivers the speed and confidence of press-fit installation while maintaining the durability and corrosion resistance that copper is known for in water supply applications.

Compatible with ASTM B88 and B75 copper tubing, the fitting features EPDM sealing elements that create a watertight seal without solder or flux. The 45° angle configuration allows directional changes in tight spaces where standard 90° elbows won't fit, making it essential for routing lines around obstacles or along walls. The double press connection—requiring two separate press operations—ensures maximum joint integrity and is the industry standard for critical junctions. Smart Connect Technology provides visual and tactile feedback during installation, confirming proper fitting engagement and reducing the risk of under-pressed connections that can lead to leaks.

This fitting is specified for plumbers, HVAC technicians, and building contractors who require fast, code-compliant installations. Copper's natural antimicrobial properties make it the preferred material for potable water systems, and the press-fit method eliminates the time and skill required for soldered joints while producing consistently reliable results. Installation requires Viega ProPress XL-C rings and V2 actuator equipment—standard in professional plumbing shops and rental services. The 2-1/2" size handles main lines and larger branch distribution in multi-story buildings and high-flow applications.

The ProPress system has become the backbone of modern commercial plumbing, valued for speed (installations 3–5 times faster than soldering), safety (no open flame on jobsites), and repeatability. Copper fittings outlast alternative materials by decades when installed correctly, making this investment in proper tooling and technique a long-term economy.
