AWENTA clamp band OP2 for duct hose diameter 100–120 mm

AWENTA clamp band OP2 is a mechanical fastening band designed for secure connection of round ventilation ducts and flexible hoses with diameters from 100 to 120 mm. Manufactured for use in residential and light commercial ventilation, extraction and HVAC systems, this clamp provides adjustable clamping force to hold duct joints, adapters and fittings in place. The product is suitable for connecting flexible ducting to rigid collars, joining sections of duct, or fixing hose ends to fans and vents where a dependable clamp is required.

Advantages

The clamp band delivers consistent, adjustable tightening to maintain a sealed and stable mechanical connection without the need for permanent adhesives. Its simple band-and-screw design allows fast installation and later re-adjustment or removal. Construction materials and finish are chosen to resist routine mechanical stresses encountered in ventilation and extraction systems, helping to reduce vibration-related loosening and air leaks when correctly fitted.

Suitable for

• Fastening round ventilation ducts with diameters 100–120 mm
• Securing flexible hoses to collars, adapters or fan outlets
• Joining short runs of ducting in residential HVAC and extraction systems
• Temporary or adjustable connections during installation, testing and maintenance

Key specifications

• Compatibility: designed for circular ducts and hoses with 100–120 mm outer diameter
• Type: adjustable band clamp with mechanical tightening
• Application area: ventilation, extraction, small commercial and residential HVAC
• Function: provides mechanical retention and adjustable sealing pressure

How to use

Position the clamp band over the overlapped section of duct or hose and collar so that the tightening mechanism sits accessible for a screwdriver or nut driver. Ensure the duct ends to be joined are fully inserted and aligned, then tighten the band evenly until the connection feels secure and slight compression of the hose or duct edge is visible. Avoid over-tightening which may deform thin-walled ducting or flexible hose. For removable connections, loosen the screw to release the band and slide it off.

Usage recommendations

For best results, inspect mating surfaces for dust and sharp edges before fitting, and use a single properly sized clamp band per joint. Where air-tightness is critical, combine the clamp with a suitable sealant or foil tape rated for ventilation systems. Periodically check clamps during maintenance to confirm tension and re-tighten if minor loosening is observed.
