Flexible duct connector
Flexible connectors are necessary for making fabric compensators. These compensators help to avoid the transmission of vibrations in spiral or rectangular ductwork and suitable for acoustic decoupling. Thus, flexible connectors frequently serve as a connecting element between devices or fans and ventilation ducts.
Flexible connectors consist of a fabric, e.g. polyester with PVC coating or glass fibre with PU coating, which is secured to sheet metal on both sides. The sheet metal can be made of galvanised steel or stainless steel.
If assembled correctly, the produced compensators are suitable for sealing class C.
Materials
Connections made of various materials such as polyester, glass silk, neoprene, silicone and many more.
Dimensions
Different widths of sheet metal and fabrics allow individual production of expansion joints.

VARIABLE SELF-ASSEMBLY SYSTEM FOR THE PRODUCTION OF FLEXIBLE CONNECTIONS
Thanks to our flex.x spigot system, you have the option of manufacturing expansion joints or elastic connection spigots (canvas spigots) yourself and all that in the usual quality. Our self-assembly kits for flexible connections are suitable for the highest air tightness requirements and are airtight - without any additional sealing tape. The self-assembly systems are suitable for both square and round air ducts, as well as for connection with our proven sliding strips or duct clips.
The finished expansion joints are used, among other things, as expansion compensation and for decoupling structure-borne noise in air ducts or HVAC systems.
- Variable and quick self-assembly system
- Airtight installation without additional sealing tape
- Suitable for connection with sliding strips and duct clips
- Flex.x PVC and flex.x welding tape can be used in accordance with VDI 6022
- No drying time, so the component can be loaded or packed immediately
Flexible strips
Flexible strips are fabric strips coated on both sides, used for the construction of compensators.The flexible strips are available in various widths and made of different materials. As the length of the connector is not extended by sheet metal, flexible strips allow the production of very compact compensators.
- Various combinations possible
- Polyester/PVC
- Polyester/PVC B1
- Fibreglass/Polyurethan
- Fibreglass/Neoprene
- Fibreglass/Aluminium
