Viega 79180 ProPress dielectric union trap 2 in x 2 in

ProPress dielectric union 2 in

The Viega 79180 ProPress dielectric union joins 2 in copper tube to 2 in FNPT threads in potable-water systems. Its bronze body and EPDM O-ring suit standard plumbing installations. The fitting installs with a press tool, removing the need for solder at the copper connection. It is intended for contractors and maintenance crews who need a dielectric transition on 2 in lines.

Pressure and temperature limits

The union is rated for a maximum operating pressure of 200 psi and a maximum operating temperature of 250 Degrees F. Bronze construction and the EPDM seal handle these conditions without degradation in normal service. No external power or active cooling is involved, so noise and power draw are not applicable. The 3 17/32 in overall length fits standard piping layouts.

Sustained service behaviour

Under continuous pressure and temperature up to the rated limits, the crimp joint and dielectric barrier maintain separation between dissimilar metals. The EPDM O-ring resists creep and retains sealing force over long periods. The fitting contains no moving parts or electronics, so performance does not vary with duty cycle. It is not suited for applications exceeding 200 psi or 250 Degrees F.
