Watts 3-inch dielectric flange copper socket fitting with brass bolts and polysulfone insulator

Watts

Watts 3" LF3110 Dielectric Flange Copper SOC 33-180°F 175psi

SKU CH-4TEG-G3C3X

A 3-inch dielectric flange with copper socket ends isolates dissimilar metals while handling 175 psi at 33 to 180°F

  • 3 in copper socket flange connects copper pipe securely
  • Polysulfone insulator blocks galvanic corrosion between dissimilar metals
  • 175 psi pressure rating handles demanding plumbing systems
  • Operates from 33 to 180 °F across hot and cold lines
  • Brass fasteners included for immediate installation

3 in Dielectric Flange Copper SOC

This Watts 3 in dielectric flange joins copper pipe with a female socket connection. Cast copper silicon alloy body handles 175 psi maximum operating pressure. Polysulfone insulator separates dissimilar metals to prevent galvanic corrosion. Includes fasteners for four bolt holes and operates from 33 to 180 degrees Fahrenheit.

Suits copper systems needing dielectric isolation

Installers connecting copper to other metals without corrosion protection will benefit. Systems requiring flanged joints larger than 3 in or threaded connections instead of socket ends should look elsewhere. Applications above 175 psi or outside the 33 to 180 degree temperature range are not supported.

175 psi maximum operating pressure

This single rating determines whether the flange matches the design pressure of the plumbing system. Exceeding it risks joint failure and leaks. Verify the system working pressure stays at or below 175 psi before specifying this fitting.

Questions about this item

What type of pipe does the 3-inch socket end of the LF3110 flange accept?

The flange has a 3-inch female socket designed for copper pipe connections.

Can the polysulfone insulator on this dielectric flange handle the 175 psi maximum operating pressure?

Yes, the polysulfone insulator is rated for the full 175 psi maximum operating pressure of the flange assembly.

How can I verify the LF3110 flange is functioning correctly after installation?

Pressurise the system up to 175 psi and confirm no leaks occur at the bolted joints or socket connections.
