ProPress Bronze Adapter 1/2" x 3/4

The Viega 79385 is a straight crimp adapter fitting designed for potable water systems. It connects a 1/2 inch copper tube on the fitting side to a 3/4 inch male NPT thread on the pipe side. The bronze body and EPDM O-ring suit professional plumbing installations requiring a secure press connection.

Pressure and Temperature Limits

This fitting carries a maximum operating pressure of 200 psi and a maximum operating temperature of 250 degrees F. These ratings define the safe working envelope for hot and cold potable water lines. Installers must ensure system conditions remain within these boundaries to maintain joint integrity and prevent leakage or material fatigue over time.

Bronze Construction and Threaded End

The bronze body provides corrosion resistance and structural strength for the 2 1/16 inch overall length. The male NPT thread on the 3/4 inch side allows direct engagement with threaded valves, tanks or female adapters without additional couplings. The press end eliminates soldering, reducing install time and fire risk on site while the EPDM seal ensures a reliable watertight joint.

Questions about this item

Which Viega 79385 ProPress adapter size fits my 1/2 inch copper tube and 3/4 inch male pipe thread?

This straight adapter joins a 1/2 inch copper tube on the fitting end to a 3/4 inch male NPT thread on the other end.

What does the 200 psi rating mean when the adapter is installed in a potable water line?

It certifies the bronze body and EPDM seal for continuous service up to 200 psi at temperatures up to 250 °F.

How does the ProPress crimp connection limit the tools and pipe I can use?

The FTG end requires a ProPress jaw set and compatible copper tubing; no threading or soldering is needed on that side.
