Exerts gripping power equal to 70 tons on connecting pipes the top-facing bolts eliminate under-digging for space to crawl under the pipe to tighten bolts while the stab-fit, one-piece design allows for easier and faster installation.
Capable of gripping and connecting pipes with 70 tons of power, the patented GRIP chain offers circular restraint around the pipe, unlike typical wedge-style restraints that point-load the pipe and make it weaker. The GRIP’s patented radial closing mechanism holds pipes tightly in place during installation, allowing full control over the gap between pipes. As the pipe applies axial pressure, the GRIP chain increasingly tightens over the pipe, preventing pullout even for HDPE pipe, which expands and contracts over time. The coupling can absorb post-installation dynamic pipe deflection of up to 4° on each end, reducing the risk of damage and cracking due to ground shifts and temperature changes, and saving resources on future pipe repairs.
