Viega 99640 3/4 Inch Press End Pipe Adapter Bronze

Product Description

The VIEGA 99640 is a 3/4 inch nominal press-end pipe adapter designed for use in PureFlow press-fit piping systems. This bronze adapter connects press-style tubing to threaded or standard pipe ends, allowing transitions within a piping assembly without soldering or open flame. It is installed by licensed plumbers and pipefitters working on residential and light commercial water distribution systems. The press-end connection style requires a compatible press tool for proper installation, delivering a reliable, leak-free joint when correctly crimped.

This adapter is suited for potable water supply lines, hydronic systems, and general plumbing distribution where a press-fit transition fitting is required. The 3/4 inch nominal size fits standard 3/4 inch press-fit tubing runs. Its bronze construction offers corrosion resistance appropriate for water service applications in both new construction and retrofit installations.

Key Features

• 3/4 inch nominal press-end connection for tool-pressed, flame-free joining
• Bronze construction for corrosion resistance in water service
• Adapter configuration allows transitions between press-fit and standard pipe ends

Compatibility

Designed for use with VIEGA PureFlow press-fit piping systems at 3/4 inch nominal pipe size. Specific compatible model numbers or system families beyond the PureFlow press product line were not provided in the available data.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and IPC guidelines. Shut off the water supply and depressurize the line before fitting installation. A VIEGA-compatible press tool with the correct jaw size must be used to achieve a proper crimp on the press-end connection. Do not attempt to install press fittings by hand compression or with non-approved tooling, as this will result in an incomplete seal.
