Spiralmate® Self-Sealing Round Duct Connector System Sold as a complete set, Spiralmate is a three-piece, self-sealing round duct connector system featuring a one-bolt closure band, providing an innovative and cost-effective solution for fast, safe, and aesthetically pleasing airtight connections. Beyond innovative design, Spiralmate offers clear advantages over traditional round connector systems. Its engineered simplicity results in a lower overall installed cost, as the complete system eliminates the need for purchasing separate components, sealants, and additional labor. Its unique one-bolt closure band not only speeds up the installation process and reduces potential leakage, but also enhances worker safety by removing labor-intensive and time-consuming screw applications. Eliminating unsightly screws and sealant creates a clean, seamless connection, ideal for architectural applications on exposed duct systems. For specialized applications, such as underground mining or tunneling, our Ventmate alternative features the same integral sealant and neoprene gasket embedded into a wider closure band to enhance the airtight seal where flush connections are not possible. Special Characteristics: Self-sealing, resulting in a considerably less overall installed cost One-piece connector clamp eliminates unsightly screws between connections Simple and easy connection that’s safer and easier to install Aesthetically pleasing design, can used as an architectural feature Strong, split-ring design adjusts to fit duct and fitting dimensions Can easily adjust duct and fittings for proper alignment every time No additional sealing required Virtually no leakage up to 18″ w.g. positive and 10″ w.g. negative pressure (complete testing data available upon request) Available in standard sizes from 8″ to 72″ in 2″ increments and in six alloys with or without mastic (consult Customer Service for additional/larger sizes and more options) Press-on inner rings are available with a double-sided pressure-sensitive adhesive to simplify double-wall installation and remove the need for costly welding Ventmate alternative available with a wider closure band for specialized applications where flush connections are not possible, such as mining and tunneling Not recommended for applications with duct gauges heavier than 16 ga. or lighter than 28 ga. Both profiles will accept 12 ga. longitudinal duct seam Installation: Related Resources To view all related resources you must log in or request access.
