Click on image above for a larger view of the Double E-Loc Coupling

The Double "E-Loc"™ coupling was designed and developed to join both smooth and ribbed HDPE innerduct, specifically for pneumatic methods of cable placement where air and water-tight integrity of the system is imperative, and where the joint is unrestrained such as in a vault, manhole or hand hole. The coupling is pressure tight to internal pressures above 200 psi unrestrained or buried. The coupler is reusable.

• Sizes 1" thru 2" duct

• Pull out tests exceed pull requirements of conduit
  manufacturer's pull tests

• No metal components
