Bronze Press-Fit Adapter for Potable Water

The Viega 79855 is a straight bronze adapter designed for potable water systems. It connects a 2 in FTG copper tube to a 1/2 in press-fit copper tube. This fitting suits plumbers and installers working on residential or commercial water distribution lines.

Verify Tube Sizes and Press Tool Compatibility

Before ordering, confirm the existing copper tubing matches the 2 in FTG and 1/2 in press-fit dimensions. Ensure the press tool and jaw set are rated for the fitting size and that the system operates within the 200 psi maximum pressure rating. The fitting is restricted from sale in certain states.
