## Long description

The Hewalex flexible duct connector DN 160 (model 90.00.05) is a rubber fabric coupling designed to join round ducts in ventilation, exhaust and flue systems where a DN 160 connection is required. The connector provides an elastic link between duct sections to reduce vibration transmission, compensate for small misalignments and allow slight axial movement. Constructed for compatibility with standard DN 160 fittings, it is suitable for use in HVAC installations, chimney flues and extraction systems that require a flexible, vibration-damping joint.
Advantages
The flexible connector reduces noise and vibration transfer between mechanical equipment and rigid ductwork, extending the lifetime of connected components. Its elastic construction compensates for minor angular and axial misalignment without the need for precise fitting, simplifying installation. The connector is lightweight, easy to handle and compatible with standard DN 160 circular duct dimensions, facilitating replacement or retrofit in existing systems.
Suitable for
HVAC ventilation duct joins with DN 160 diameter
Exhaust systems and extraction fans requiring vibration isolation
Chimney flue connections that accept flexible couplings
Retrofit and maintenance operations where minor misalignment is present
Key specifications
Connection diameter: DN 160 (for round ducts)
Material: elastic rubber fabric with reinforcement (suitable for flexible coupling)
Function: vibration damping and compensation for axial/ angular misalignment
Compatibility: designed for standard DN 160 circular duct fittings
Installation: clamp or bolt fastening to mating flanges or duct ends (fasteners not included)
How to use
Position the flexible connector between the two DN 160 duct ends ensuring the connector covers the mating surfaces evenly. Secure the connector with appropriate clamps or bolts to the duct flanges or sleeve, following the recommended tightening sequence to avoid deformation. Check that the connector is not twisted and allow a small free length for elastic movement. After installation, inspect the joint for leaks and retighten fasteners if necessary.
Usage recommendations
Use the Hewalex flexible duct connector in applications where moderate temperature and pressure conditions are present and where the manufacturer’s material limits are met. Avoid exposure to aggressive chemicals or temperatures beyond the material’s rated range. Regularly inspect the connector during scheduled maintenance for signs of wear, cracking or loss of elasticity and replace if deterioration is observed.
