Product Description
The VIEGA 79300 is a zero-lead bronze female adapter built for the ProPress press-fit system, incorporating Viega Smart Connect technology. It transitions a press connection to a female NPT threaded connection, making it a reliable fitting for joining copper tubing to threaded pipe or components in pressurized plumbing systems. The 1/2 inch by 1/2 inch sizing suits common residential and light commercial branch lines. Smart Connect technology allows leak testing before the system is pressurized, giving installers a clear verification step without additional tools. Licensed plumbers and pipefitters are the primary installers for this fitting.
This adapter is used in plumbing applications where a press-fit copper system meets a female-threaded component such as a valve, pump, or fixture supply line. The Press x FNPT configuration makes it well suited for retrofit and new construction work where speed of installation and a flame-free connection are priorities. It is appropriate for potable water service given its zero-lead bronze construction.
Key Features
- Zero-lead bronze construction meets potable water compliance requirements
- Smart Connect technology enables leak detection prior to full system pressurization
- Press x FNPT configuration connects copper press systems to female-threaded components
- Flame-free installation reduces jobsite fire risk and eliminates the need for soldering permits in many jurisdictions
- 1/2 inch size fits standard residential and light commercial plumbing branch lines
Compatibility
Designed for use with the Viega ProPress press-fit system for copper tubing. Compatible fittings require a Viega-approved press tool and the appropriate jaws or rings for 1/2 inch ProPress connections.
Installation Notes
Installation must be performed by a licensed plumber using a Viega-approved pressing tool with the correct 1/2 inch jaw set. Shut off the water supply and depressurize and drain the line before making any connections. Ensure the pipe end is cut square, deburred, and fully inserted to the pipe stop before pressing. Verify the unpressed fitting indicator per Smart Connect guidelines before pressurizing the system.
