  • Withstands 180 °F maximum temperature
  • Meets ANSI B 16.42 dimensional standard
  • FIP threads install without soldering

Dielectric Flange for Galvanic Isolation

The Watts 3200 dielectric flange separates dissimilar metals in a piping system to prevent galvanic corrosion. It suits installers working on 2-1/2 inch FIP threaded connections in commercial or residential plumbing.

Rated for 175 psi and 180 Degrees F

The malleable iron body with galvanised finish handles a maximum pressure of 175 psi and a maximum temperature of 180 Degrees F. The Buna-N gasket and polysulfone insulator maintain the dielectric break under normal operating conditions without additional power or active cooling.

ANSI B 16.42 Compliant FIP Threads

Threaded FIP x FIP ends meet ANSI B 16.42 and federal tensile specifications for reliable joint integrity. The 2-1/2 inch pipe size dictates matching fittings, while the polysulfone insulator requires no special tools for assembly beyond standard pipe wrenches.

Questions about this item

How is the Watts 3200 2-1/2 in FIP dielectric flange installed, and what step is commonly missed?

Thread the FIP ends onto the mating pipe threads using appropriate sealant; the step often missed is verifying the polysulfone insulator and Buna-N gasket stay seated and undamaged during tightening.

What maintenance or replacement will this dielectric flange need over time?

Inspect the Buna-N gasket periodically for hardening or cracking and replace it if leaks appear; the galvanized malleable iron body and polysulfone insulator generally do not require scheduled replacement.

What limit appears first on the Watts 3200 flange under sustained pressure and temperature?

The 175 psi pressure rating at 180 °F is the primary limit; exceeding either value can compromise the gasket seal and insulator integrity.
