## Long description

Round duct connector AWENTA KO100-21 100 mm white is a circular ventilation accessory designed to join or extend 100 mm diameter round ducts. Constructed for straightforward alignment between duct sections, this connector provides a mechanically stable junction that supports residential and light-commercial HVAC installations, repairs and system modifications. The white finish offers a neutral appearance that integrates with common interior and utility spaces.
Advantages
The connector enables reliable, concentric coupling of round duct segments with minimal air leakage when installed correctly. Its standard 100 mm diameter fits typical small ventilation runs and replacement parts, simplifying upgrades and repairs. The white coating helps resist surface soiling and allows for a discreet installation in visible areas. The simple cylindrical shape reduces installation complexity and requires no special tools beyond basic fastening or sealant materials.
Suitable for
Joining two 100 mm round ventilation ducts
Extending duct runs in residential HVAC systems
Repairing or replacing damaged duct sections
Small commercial ventilation projects and modifications
Key specifications
Diameter: 100 mm nominal
Shape: circular / cylindrical connector
Finish: white surface coating
Application: ventilation duct coupling and extension
Typical installation environment: indoor residential and light-commercial spaces
How to use
Position the connector between the two duct ends, ensuring concentric alignment. Slide each duct end over the connector until fully seated, then secure the joint with appropriate fasteners or clamp bands if required. For improved airtightness, apply ventilation-grade sealant or aluminum foil tape around the circumferences of the connection. Verify that the assembled run remains straight and supported to avoid stress on the joint.
Usage recommendations
Use compatible 100 mm round ducts and ensure supporting brackets or hangers are installed close to the connector to prevent sagging. Avoid exposing the connector to direct external weather without appropriate external ducting or protective measures. Periodically inspect joints for looseness or seal degradation and re-tighten or re-seal as needed to maintain system performance.
