Product Description
The VIEGA 77023 is a 3/4 inch copper 45-degree elbow fitting designed for use with the Viega ProPress press-fitting system. It incorporates Smart Connect technology, which features a leak path built into the fitting sleeve that allows an unpressed connection to be identified during pressure testing before the system is put into service. This fitting is installed using a compatible ProPress pressing tool and requires no open flame, solder, or flux. Plumbers and pipefitters working on commercial and residential copper piping systems will find this fitting suited to fast, reliable installations.
This elbow is used in plumbing applications where a 45-degree directional change is needed in a 3/4 inch copper line. The ProPress system is widely used in residential and light commercial plumbing, hydronic heating, and mechanical piping where press-fit connections are preferred over soldered joints. It is appropriate for retrofit work as well as new construction where speed and code compliance with press-fitting standards are priorities.
Key Features
- Smart Connect technology enables detection of unpressed connections during pressure testing
- Press-fit installation eliminates the need for open flame, solder, or flux
- 3/4 inch by 3/4 inch copper construction for consistent performance in copper piping systems
- 45-degree angle provides precise directional routing in tight or angled run configurations
- Lightweight at 0.153 pounds, reducing handling fatigue during high-volume installations
Compatibility
Designed for use with the Viega ProPress press-fitting system in 3/4 inch copper plumbing applications. Requires a compatible Viega ProPress pressing tool and jaw set rated for this fitting size.
Installation Notes
Installation must be performed by a licensed plumber using a compatible ProPress pressing tool with the correct jaw configuration for 3/4 inch fittings. Shut off and depressurize the water supply before cutting into any existing line. Always conduct a system pressure test after installation to confirm all connections are fully pressed, which is where the Smart Connect feature provides a critical verification step. Refer to local plumbing codes and the applicable IPC or IFGC standards for press-fit fitting requirements in your jurisdiction.
