Bronze Press-Fit Adapter for Potable Water

The Viega 79320 is a straight adapter that joins a 1 in press-fit copper tube to a 1/2 in FNPT thread. It is designed for potable water systems and suits plumbers who need a reliable transition between press and threaded connections.

Bronze Body with EPDM Seal

The fitting is made from bronze to ASTM B75 and ASTM B88, rated for 200 psi and 250 Degrees F. Its press-fit end uses an EPDM O-ring for a secure, leak-free joint without soldering, while the FNPT end accepts standard threaded pipe or components.

Verify Tube Size and Thread Compatibility

Confirm that the existing copper tube is 1 in CTS and that the mating component has a 1/2 in FNPT thread. The overall length is 1 27/32 in, so check available space before ordering.
