ProPress Reducing Tee for Potable Water

The Viega 79660 ProPress reducing tee connects copper tubing in potable water systems using press-fit joints on all three outlets. It joins tube sizes of 1-1/2 in, 1 in and 3/4 in with a copper body and EPDM O-ring seals. The fitting includes a center stop dimple and carries a maximum operating pressure of 200 psi.

Verify Tubing and Press Tool Compatibility

Before ordering, confirm that the existing copper tubing matches the three listed tube sizes and that the tubing is approved for press-fit connections. Ensure a compatible press tool and jaw set are available for the specific diameters. Check local plumbing codes for any restrictions on press fittings in potable water installations.

Suits Installers Reducing Main Lines to Fixtures

This reducing tee suits plumbers transitioning a 1-1/2 in main line down to 1 in and 3/4 in branches in a single fitting. It is not intended for drainage, gas or high-temperature hydronic systems that require different seal materials. Installers needing equal tees, different tube size combinations or threaded connections should select alternative fittings.
