Watts LF3006 Dielectric Union 1-1/2 In FIP 250 psi

SKU CH-FQ3R-DKZ4W

Connects dissimilar metal piping to prevent galvanic corrosion, rated for 250 psi and 33 to 180 degrees F

  • Prevents galvanic corrosion with dielectric insulator
  • Withstands 250 psi maximum operating pressure
  • Operates from 33 to 180 degrees F
  • Female threaded connections for secure installation
  • Zinc-plated malleable iron resists corrosion

Dielectric Union for Dissimilar Metals

The Watts LF3006 dielectric union separates dissimilar metal piping to prevent galvanic corrosion in plumbing systems. It connects a 1-1/2 inch female threaded end to another 1-1/2 inch female threaded end with an overall length of 2 3/4 inches. The insulator uses polysulfone and the gasket uses NBR material. It suits installers needing a straight dielectric coupling rated for potable water service.

Polysulfone Insulator and NBR Gasket

The polysulfone insulator electrically isolates the two malleable iron body halves while the NBR gasket seals the joint. A malleable iron union nut draws the assembly together. These components combine to block stray currents that accelerate pipe degradation. The materials are selected for compatibility with typical water chemistry found in residential and commercial supply lines.

Malleable Iron Body with Zinc Plated Finish

One body half features a zinc plated galvanized coating and the other a black finish, both made from malleable iron for mechanical strength. Female threaded connections on both ends accept standard NPT pipe threads without adapters. The union is rated for 250 psi maximum operating pressure across a temperature range of 33 to 180 degrees Fahrenheit. It is not intended for applications exceeding these pressure or temperature limits.

Questions about this item

How often should the NBR gasket be inspected or replaced?

Inspect the NBR gasket annually and replace it if you see cracking, hardening or any sign of leakage.

What is the first limit reached during continuous operation at high temperature?

The 180 degrees F maximum operating temperature is the first limit reached under sustained hot-water use.

Does the polysulfone insulator or zinc-plated malleable iron body add noticeable heat to the line?

The polysulfone insulator blocks electrical continuity while the zinc-plated malleable iron body conducts heat normally; neither component generates additional heat.
