## Long description

The WADEX Chimney Inner Sleeve 126 D160/120 is a concentric flue liner designed to provide a sealed transition between a 160 mm outer-diameter duct and a 120 mm inner outlet. This component fits inside chimney systems to align and connect sections where a reduction in diameter is required. Constructed for standard residential and light-commercial venting applications, the sleeve helps maintain flue alignment and supports safe passage of combustion gases through a stepped connection.
Advantages
The inner sleeve delivers a compact and concentric reduction that preserves the central alignment of flue sections and minimizes turbulence at the joint. Its design facilitates a tight connection between different pipe diameters, reducing the risk of gas leakage and ensuring a consistent flue path. The component is suitable for use where a reliable step-down coupling is needed without extensive modification to existing ductwork.
Suitable for
 Aligning and connecting chimney sections from 160 mm to 120 mm
 Residential chimney and venting systems
 Light-commercial flue installations requiring a diameter reduction
 Retrofit projects where an internal concentric reducer is needed
Key specifications
 Type: concentric flue inner sleeve for step-down connection
 Input diameter: fits ducts with 160 mm outer diameter
 Output diameter: connects to 120 mm inner outlet
 Application: internal chimney/vent liner component for gas/combustion flues
 Typical installation environment: residential and light-commercial venting systems
How to use
Install the sleeve by inserting the larger end into the 160 mm duct section and aligning the 120 mm outlet with the downstream pipe. Ensure mating pipe ends are clean and free of debris before assembly. Depending on the system, secure the sleeve with appropriate fasteners or clamps and, where required, use high-temperature sealant or gasket material to create an airtight joint. Verify alignment and clearance within the chimney cavity and follow local codes and manufacturer guidance for safe connection and support.
Usage recommendations
Use the sleeve only within compatible chimney systems and with pipe materials rated for the operating temperatures and combustion type in your installation. Confirm that the concentric reduction matches the ventilation requirements of the appliance and that sealing and fixation meet local building regulations. When in doubt, consult a qualified installer or chimney professional to ensure safe and code-compliant installation.
