## Long description

AWENTA KO125-21 Ø125 mm white round duct connector is a component for joining or extending circular ventilation ducts with a 125 mm internal diameter. Manufactured to provide a consistent coupling between compatible duct sections, this white connector is intended for use in residential and light-commercial HVAC systems where straightforward duct connections, extensions or simple repairs are required. The design focuses on maintaining airflow continuity and a compact fit within ventilation runs.
Advantages
The connector offers a standardized diameter match for Ø125 mm ducts, a neutral white finish that integrates with common ducting and interior spaces, and a compact, lightweight form that simplifies handling and installation. Its uniform circular profile reduces turbulence at joint locations and supports straightforward alignment of duct sections without the need for complex fittings.
Suitable for
Joining two sections of Ø125 mm round ventilation duct
Extending existing duct runs in residential ventilation systems
Minor repairs and replacements in light-commercial HVAC installations
Routing airflow between fan units, vents and duct branches using Ø125 mm connections
Key specifications
Nominal diameter: 125 mm internal diameter suitable for standard Ø125 mm round ducts
Shape: circular connector compatible with round duct profiles
Color: white finish for discreet integration
Material characteristics: lightweight for easy handling (material composition not specified)
Application environment: indoor ventilation and HVAC systems for residential and light-commercial use
How to use
Ensure both duct ends to be connected are clean, free of sharp edges and properly aligned. Insert each duct end into the connector until a secure fit is achieved; depending on the duct material, the connector may be pushed over the duct ends or the ducts may be slid into the connector. Verify alignment to maintain uninterrupted airflow. Where required by installation practice, secure the joint with metal tape, clamps or appropriate fasteners and seal with duct sealant to prevent air leakage.
Usage recommendations
Use this connector indoors within systems designed for Ø125 mm round ducts. For long runs or higher-pressure applications, combine with appropriate support brackets and sealing methods. Inspect joints after installation for air tightness and retighten or reseal as necessary. Avoid outdoor exposure unless installed within protected ductwork.
