Engineered for robust performance in various applications, this aluminum barbed coupler is specifically designed for SDR smooth wall exterior ducts. Each barbed ring provides a reliable full-circumference seal, enhancing sealing efficiency as internal air pressure increases, making it ideal for systems requiring high pull-out strength. The double sealing protection effectively safeguards against air leakage, ensuring optimal functionality. Installation is straightforward with a hydraulic coupling press, allowing for a press-on connection that is both secure and efficient. This coupler is suitable for environments such as manholes and direct bury applications, though it is important to note that it is not recommended for wet or submerged conditions. As a durable solution crafted from 6061-T6 aluminum, it meets the demands of reliable underground and aerial systems.
