Viega Steel Press-Fit Tee

The Viega 25405 is a zinc nickel-plated steel tee designed for non-potable water systems. It connects two 3/4 inch press-fit ends with a 1/2 inch female pipe thread branch. The fitting carries an EPDM O-ring and is rated for 200 psi at 250 degrees F.

Press-Fit Connection Benefits

The press-fit ends eliminate the need for threading or soldering on the main run, reducing installation time and the risk of leaks at those joints. The 1/2 inch FPT branch allows a straightforward transition to threaded components or fixtures without additional adapters.

Capacity and System Limits

This tee handles pressures up to 200 psi and temperatures up to 250 degrees F, covering typical hydronic heating and cooling loops. It is not approved for potable water service, so it cannot be used in drinking water supply lines.

Questions about this item

How often should the EPDM O-ring on this 3/4" press tee be inspected or replaced?

The EPDM O-ring is rated for continuous service up to 250°F and 200 psi; inspect it whenever the system is opened or pressure-tested, and replace it if any cracking or permanent deformation is visible.

What pressure limit will this steel tee reach first during sustained operation?

The fitting is rated for a maximum operating pressure of 200 psi, so that is the ceiling you must not exceed under steady-state conditions.

How hot does the zinc-nickel body get when the line runs at the 250°F temperature rating all day?

The steel body will essentially match the fluid temperature, so expect surface temperatures near 250°F during continuous high-temperature operation.
