Permasert® Couplings

The heart of our complete main-to-meter gas distribution system, Permasert couplings are safe and remarkably easy to install. Permasert EFV couplings are available in many different configurations and sizes, including a special repair or "cut-in" coupling for service line EFV retrofitting. All Permasert couplings provide a pull-out strength greater than the connected polyethylene tubing.

  • Ideal for retrofitting EFVs into service lines or for new installations
  • Tee and Wye fittings are available and are designed to accommodate branch service installations
  • Sizes from 1/2" CTS to 1-1/4" IPS
  • Available for all plastic pipe wall thicknesses
  • Molded from ASTM D 2513, gas grade polyethylene materials

  • Available with EFV located in valve port opening to allow for easy manual reset of the EFV without back pressuring the service line
  • Controlled reset of the EFV (not subject to waiting for pressure equalization)
  • Provides the ability for manual shut off under any condition of flow
  • Allows timely and easy purging of the repaired service line
