Engineered for reliability and efficiency, this aluminum barbed coupler is designed specifically for SDR smooth wall exterior duct applications. Featuring a barbed compression-type coupling for HDPE innerduct, it ensures a robust and secure connection that minimizes the risk of air leakage with double sealing protection. The installation process is simplified thanks to its press-on design, which requires a hydraulic coupling press for effortless and precise placement. With each barbed ring providing a full-circumference seal, this coupler is an essential component for any installation needing durability and superior performance in pipe and conduit systems.
