Viega VIE79130 Propress 3/4 in Lead-free Press Union

Product Description

The VIEGA VIE79130 is a 3/4-inch lead-free copper press union designed for use with the Viega ProPress system. This fitting creates a permanent, leak-free joint without open flame, using a pressing tool to mechanically compress the fitting onto copper tubing. It is intended for potable water, hydronic heating, and general plumbing applications where lead-free compliance is required. Plumbers and pipefitters install this union to join two sections of copper tubing in a straight-line configuration, particularly in retrofit or repair scenarios where torch access is restricted or prohibited.

This union is suited for both residential and light commercial plumbing installations. It is used wherever a straight copper press connection is needed on 3/4-inch tubing runs, including domestic hot and cold water systems, radiant heating loops, and mechanical room piping. The ProPress system is widely adopted in new construction and renovation work where no-flame installation is a code, insurance, or site-safety requirement.

Key Features

• Lead-free construction meets Safe Drinking Water Act compliance requirements for potable water systems
• No-flame press connection eliminates the need for soldering or torch work at the joint
• Union configuration allows straight-line joining of two copper pipe sections
• Compatible with standard Viega ProPress pressing tools and jaw sets for 3/4-inch fittings
• Permanent mechanical connection suitable for concealed and in-wall installations

Compatibility

Designed as an OEM-style replacement and standard fitting for use within the Viega ProPress copper press fitting system on 3/4-inch copper tubing.

Installation Notes

Installation requires a Viega-compatible pressing tool with the appropriate 3/4-inch jaw set. Shut off and depressurize the water system before cutting into any existing line. This fitting is installed by licensed plumbers and follows applicable local plumbing codes and ASTM standards for copper press connections. Do not press the fitting if the tubing interior is wet or if the fitting is not fully seated on the pipe end.
