Viega 25575 Press-Fit Adapter

This Viega 25575 straight adapter connects a 3/4 inch press-fit pipe to a 1/2 inch FNPT thread. It is designed for non-potable water applications in commercial or industrial piping systems. The steel body features a zinc nickel-plated finish for corrosion resistance.

Sustained Pressure and Temperature Performance

The fitting is rated for a maximum operating pressure of 200 psi and a maximum operating temperature of 250 degrees F. These ratings apply to continuous service conditions rather than momentary spikes. The EPDM O-ring maintains its seal throughout the specified pressure and temperature range.

Thermal Stability and Leak Resistance

The steel construction and plated finish withstand thermal cycling up to the rated temperature without degradation. The press-fit connection eliminates the need for open-flame soldering, reducing installation fire risk. The EPDM seal material resists hardening and cracking under normal hot-water operating conditions.

Questions about this item

Does the 25575 adapter make noise or get hot when water runs through it continuously?

No moving parts inside the 25575, so it runs silently and stays at water temperature; the steel body and zinc-nickel finish handle up to 250 °F and 200 psi without vibration or heat build-up.

What tools and pipe must I already have to press the 3/4 in side of the 25575?

You need a Viega ProPress XL press tool with the correct 3/4 in jaw, plus 3/4 in tubing approved for press-fit; the 1/2 in FNPT side threads onto standard 1/2 in NPT pipe or fittings.

Can I connect the 1/2 in FNPT end of the 25575 to older galvanised or copper pipe?

Yes, the 1/2 in FNPT threads mate with any 1/2 in NPT male thread, so it joins legacy galvanised, copper or brass pipe; use appropriate thread sealant for a leak-free seal.
