Clamp band AWENTA OP6 for duct/ventilation connections, diameter 140–160 mm

AWENTA OP6 clamp band is a metal fastening band designed for secure mechanical joining of circular ducts, fittings and flexible hoses with diameters from 140 to 160 mm. Intended for ventilation and HVAC systems, the clamp band provides an even, adjustable clamping force to create airtight and stable connections between duct sections and components. The simple construction allows rapid installation and reliable performance in both new installations and repair work.

Advantages

The clamp band is made from corrosion-resistant metal and shaped to encircle round ducting uniformly, reducing the risk of leaks and mechanical displacement. Its adjustable profile accommodates slight diameter variations within the 140–160 mm range, enabling compatibility with common circular ducts and flexible hoses. The design offers consistent pressure distribution around the joint and a compact footprint that does not obstruct airflow.

Suitable for

• Joining circular metal ducts with diameters between 140 and 160 mm
• Securing flexible ventilation hoses to rigid fittings
• HVAC installations, maintenance and system upgrades
• Temporary or permanent mechanical fastening of round duct components

Key specifications

• Material: metal, corrosion-resistant finish suitable for ventilation environments
• Applicable diameter range: 140–160 mm
• Type: adjustable clamp band for circular ducts and hoses
• Function: provides mechanical seal and stable lateral support for duct joints

How to use

Position the clamp band around the overlapping ends of the circular ducts or around the hose and fitting interface so the band sits evenly around the circumference. Tighten the clamp using the recommended tool or fastener until the band applies firm, uniform pressure without deforming the duct. Verify that the joint is aligned and that no gaps remain; when appropriate, apply duct sealant or tape over the seam for enhanced airtightness. For removal, loosen the fastener and slide the band off.

Usage recommendations

Confirm the actual outer diameters of the ducts or hose before selection to ensure compatibility within the 140–160 mm range. Use appropriate hand or power tools to achieve a snug fit without over-tightening, which can distort thin-sheet ducting. For long-term airtightness in ventilation systems, pair the clamp band with suitable sealing materials and inspect joints periodically as part of regular HVAC maintenance.
