Watts LF3006 Dielectric Straight Coupling 1 in

SKU CH-F5HC-8Y0J2

Dielectric straight coupling connects 1 in threaded steel pipe, zinc-plated galvanised finish with polysulfone insulator and NBR gasket, rated 250 psi from 33 to 180 Degrees F

  • Prevents galvanic corrosion with dielectric polysulfone insulator
  • Handles 250 psi maximum operating pressure reliably
  • Operates from 33 to 180 degrees Fahrenheit
  • Zinc-plated galvanised steel resists corrosion effectively
  • LF3006 model ensures dependable threaded connection

Dielectric Straight Coupling 1 in

The Watts LF3006 dielectric straight coupling connects two 1-inch female threaded steel pipes while preventing galvanic corrosion between dissimilar metals. It is intended for plumbing installers and maintenance crews who need a reliable insulated joint in potable water or hydronic systems.

Thread and pressure compatibility

Verify that both pipe ends are 1-inch female threaded and rated for at least 250 psi maximum operating pressure. Confirm the system temperature will stay within the 33 to 180 degrees F range so the polysulfone insulator and NBR gasket remain effective.

Sustained pressure and temperature performance

Under continuous service the coupling maintains its dielectric barrier and seal at the full 250 psi rating across the stated temperature span. The zinc-plated galvanized steel body and steel nut resist deformation during long-term pressurised operation without the pressure spikes seen in brief test bursts.

Highlights

  • Prevents galvanic corrosion with dielectric polysulfone insulator
  • Handles 250 psi maximum operating pressure reliably
  • Operates from 33 to 180 degrees Fahrenheit
  • Zinc-plated galvanised steel resists corrosion effectively
  • LF3006 model ensures dependable threaded connection

Questions about this item

What comes in the box and what extra parts are needed for installation?

The box contains the Watts LF3006 dielectric straight coupling with zinc-plated galvanised steel body, black steel nut and built-in polysulfone insulator with NBR gasket. You must supply matching 1-inch threaded pipe or adapters and thread sealant.

Which version of this coupling should I choose for my pipe size?

This model is a single 1-inch female threaded version rated 250 psi from 33 to 180 °F with 2 1/2-inch overall length; choose it when those exact dimensions and pressure range match your system.

What does the 250 psi rating mean once the coupling is installed?

It means the joint can continuously handle 250 psi water pressure between 33 and 180 °F without leakage or insulator failure, provided the mating threads are properly sealed and supported.
