ProPress Adapter for Potable Water

The Viega 79375 is a straight crimp adapter designed for potable water systems. It connects a 1/2 inch copper tube fitting to a 3/8 inch male NPT thread. The bronze body and EPDM O-ring provide corrosion resistance for plumbing installations. It suits professionals and DIYers needing a secure, press-fit transition.

Bronze Construction and Press-Fit Connection

The adapter uses a bronze fitting material with an EPDM O-ring for sealing. Its ProPress design eliminates the need for soldering, open flames or threading compounds during installation. The straight shape allows direct in-line connection between dissimilar pipe sizes. A 1 3/4 inch overall length keeps the joint compact within wall cavities or tight mechanical rooms.

Rated for 200 psi and 250 Degrees F

The fitting withstands a maximum operating pressure of 200 psi and a maximum operating temperature of 250 Degrees F. These ratings cover typical hot and cold potable water distribution. The press connection maintains seal integrity under thermal cycling without loosening. It is not intended for gas, oil or high-pressure hydraulic circuits beyond the stated limits.

Questions about this item

How much pressure can the ProPress 79375 adapter handle before it leaks?

The fitting is rated for a maximum operating pressure of 200 psi, so it will hold up to that level in potable water systems.

What size copper tube and thread does this straight adapter connect?

It joins a 1/2 in copper tube on the press side to a 3/8 in male NPT thread on the other side.

Which tool and jaw are needed to press the 79375 fitting onto the tube?

Use a Viega ProPress tool with the correct 1/2 in jaw; insert the tube fully, then press once — do not re-press the same joint.
