Clamp band AWENTA OP8 for ducting, model OP8, diameter 160–180 mm

AWENTA clamp band OP8 is a metal fastening accessory designed for circular ventilation ducts with diameters from 160 to 180 mm. It provides a secure mechanical connection between duct sections and supports round conduits in HVAC systems used in residential and commercial buildings. The band is intended for assembly, repair and reinforcement of ventilation runs where a reliable, stable clamp is required.

Advantages

The clamp band is made of durable metal offering stable clamping force and resistance to deformation under normal operating conditions. Its shape and fastening method ensure even pressure distribution around the duct circumference, minimising air leakage at joints. The product's simple construction allows quick fitting and reduces installation time while providing long-term mechanical support for duct sections.

Suitable for

• Joining two sections of round ventilation ducting with diameters 160–180 mm
• Repairing or reinforcing damaged or loose duct joints
• Securing circular conduits in residential and light commercial HVAC installations
• Temporary or permanent mechanical support for duct runs

Key specifications

• Compatible duct diameter range: 160–180 mm
• Material: metal construction for mechanical strength
• Designed for use with round ventilation ducts and conduits
• Type of fastening: clamp band style providing circumferential grip

How to use

Position the clamp band around the abutting ends of the duct sections so that it covers the joint evenly. Tighten the fastening mechanism according to the manufacturer's recommended torque or until the band provides a secure, uniform grip without crushing the duct. Verify alignment of the duct run and check for gaps or misalignment after installation. For repairs, remove any debris or torn material from the joint before applying the clamp band to ensure proper contact and sealing.

Usage recommendations

Use the clamp band in combination with appropriate sealing tape or gasket if airtight performance is required; avoid overtightening to prevent deformation of thin-wall ducting. Inspect installed clamps periodically as part of routine HVAC maintenance.
