ProPress adapter for potable water systems

The Viega 79380 is a straight crimp adapter fitting designed for potable water installations. It connects a 1/2 in copper tube on the FTG side to a 1/2 in male NPT thread on the other. The bronze body includes an EPDM O-ring and carries a maximum operating pressure of 200 psi at 250 Degrees F.

Suits installers using ProPress tooling on bronze

This adapter suits plumbers who need a flameless, press-fit transition from copper tubing to threaded components in hot or cold water lines. It is not for installers who require a female-threaded outlet, a reducing size, or a fitting approved for gas or fuel-oil service.

Verify tube compatibility

Before ordering, confirm that the existing pipe is 1/2 in copper tubing suitable for ProPress connections. Ensure a compatible press tool and jaw set are on site to complete the crimp joint, and check that the system design stays within the 200 psi and 250 Degrees F limits.

Questions about this item

What size copper tubing and pipe thread do I need to connect the 79380 adapter?

The adapter fits 1/2 in copper tube on the press side and 1/2 in male NPT on the threaded side.

Can I press this bronze adapter onto existing 1/2 in copper pipe without re-piping?

Yes, the ProPress connection works on standard 1/2 in copper tube, so you can join it to the pipe you already have.

How do I verify the joint is holding after I press the 79380 fitting?

Pressurise the system up to 200 psi and check for leaks; the EPDM O-ring seals at up to 250 °F.
