The original RED flexible tube

Ready-to-install flexible tube for connection to all standard roof fans.


The flexible tube for all standard ventilation systems. The free end of the hose is pushed onto the lower end of the ventilator duct and fixed in place with the pre-assembled hose clamp. The connection sleeve is pushed into the underlying connection piece on the ventilation duct. Check that the lip seal inserted is properly seated in the connection piece during installation. Socket position when installed on an incline with a min. of 45°.


The tube is made from pure PVC and reinforced by an internal PVC-coated spring steel spiral. Experience the quality for yourself: wave goodbye to simple coated webbing and loose, bare and simple metal spirals that fray the tube walls when exposed to alternating loads – KALA, for quality that lasts.
The design ensures that the entire ventilation cross section is maintained at all times, even in the case of excess conduits. The stainless steel hose clamp guarantees a firm hold and good durability.
