Reducing Tee for Press-Fit and FPT Connections

This Viega 25416 reducing tee joins a 3/4 inch press-fit line, a 1 inch press-fit line and a 3/4 inch female pipe thread branch. The steel body with zinc nickel plating is rated for non-potable water systems up to 125 psi and 180 degrees Fahrenheit. Installers working on hydronic heating or industrial piping can use it to transition between press and threaded networks.

Steel Construction with HNBR Seals and Zinc Nickel

The fitting uses HNBR O-rings on both press ends to create a permanent, leak-tight seal when crimped with compatible jaws. Zinc nickel plating protects the steel from corrosion in closed-loop hydronic or chilled-water circuits. Because the press connections eliminate threading or soldering on two ports, assembly time on site is reduced and no open flame is required.

Supplied as a Single Fitting Without Tools

The box contains only the reducing tee; press jaws, crimp rings and thread sealant must be sourced separately. This suits contractors who already own Viega press tools and standard pipe dope for the FPT branch. Projects needing multiple tees or a complete press-tool kit will require additional line items.

Questions about this item

What pressure does the 125 psi rating limit on this press-fit tee?

The 125 psi maximum operating pressure caps the system pressure for non-potable water applications using this steel reducing tee.

What pipe diameters must match the 3/4 in and 1 in press-fit ends and the 3/4 in FNPT branch?

Side A requires 3/4 in pipe, Side B requires 1 in pipe, and the branch takes 3/4 in FNPT threads for the connection.

How is the zinc nickel-plated steel tee installed and which step is often missed?

Press the 3/4 in and 1 in ends onto prepared pipe with a compatible press tool, then thread the 3/4 in FNPT branch; the step often missed is verifying the HNBR O-ring seats fully before pressing.
