Engineered for high performance and durability, this aluminum barbed coupler is specifically designed for use with SDR smooth wall exterior duct applications. Its innovative barbed compression-type coupling provides a secure fit for HDPE innerducts, ensuring an effective full-circumference seal that prevents air leakage, even under varying internal pressure conditions. The coupler's robust construction from 6061-T6 aluminum allows for high pull-out strength, while the double sealing protection adds an extra layer of reliability during installation. Utilizing a hydraulic coupling press for installation simplifies the process, making it a practical choice for professionals seeking efficiency and effectiveness in their piping solutions.
