Large Diameter Coupler

Why Use Large Diameter Electrofusion Couplers

Narrow trenches and hard to reach locations are ideal for electrofusion. These locations are often inaccessible to butt fusion machines due to limited space or difficult to move pipe. This user friendly technology takes the art out of PE welding, and may be used to join pipe ends or repair damaged pipe.

Why Use Our Large Couplers

Because SMART-JOINT means quality, reliability, and global presence! With world-class customer service, we offer unmatched supply chain support and technical service. These couplers are the result of 40 years of innovation-driven growth in plastic pipe joining technology.
