SIMpull™ Couplers: Double E-LOC Conduit Coupling

Double E-LOC & Double E-LOC Transition Couplings



• Can withstand 200 psi internal pressure
• Provide pull-out resistance in excess of ASTM standards for HDPE
• Sizes from 3/4" to 4" available
• No additional tools required for installation

Applications and Features:

• The Double E-LOC is a locking compression coupling used to join smooth, ribbed, corrugated or Figure 8 High Density Polyethylene (HDPE) conduit. The locking, pressure-tight design makes the Double E-LOC an ideal coupling for pneumatic cable placing applications when air and watertight integrity of the system is imperative. Unmatched pressure ratings, pull-out resistance, no metal parts, and no special tools make the Double E-LOC the preferred coupling. Lock rings specially designed to grip rigid PVC and steel pipe are also available.
• Double E-LOC Transition Couplings have the same great features as the Double E-LOC Couplings, but provide the ability to connect conduit of different sizes. Lock rings designed to grip PVC and steel allow for a single coupling to transition to both a dissimilar size and dissimilar material.
