Almeva FLEX connector FLEX/STARR DN 80 – chimney/flue pipe flexible joint DN80

Almeva FLEX connector FLEX/STARR DN 80 is a flexible joint for chimney and flue pipe systems with a nominal internal diameter of DN80. Designed to connect rigid stove, boiler or flue sections, this flexible connector compensates for minor misalignments and thermal movement while helping to dampen vibration. It is intended for use in residential heating installations where a secure, adaptable connection between the appliance outlet and the chimney is required.

Advantages

The FLEX/STARR DN 80 flexible connector offers a combination of elasticity and stability that simplifies installation and accommodates small alignment errors between components. Its flexibility reduces stress on rigid pipes and appliance outlets caused by thermal expansion and mechanical vibration. The product is compact and straightforward to fit, enabling faster assembly and easier maintenance compared with permanently rigid joints.

Suitable for

• Connecting stoves to chimney systems in residential buildings
• Connecting boilers and water heaters to flue pipes
• Providing vibration isolation between appliances and rigid chimneys
• Compensating for small alignment deviations in flue installations

Key specifications

• Nominal diameter: DN80 (suitable for flue systems with 80 mm internal diameter)
• Function: flexible joint for chimney and flue pipe connections
• Application: residential heating systems (stove, boiler, flue)
• Performance: accommodates thermal movement and minor misalignment; reduces vibration transmission
• Installation: compact design for inline connection between rigid sections

How to use

Measure the appliance outlet and chimney or flue pipe to confirm compatibility with DN80. Position the flexible connector between the appliance spigot and the corresponding flue pipe or chimney section, ensuring an overlap sufficient for a secure fit. Secure connections according to the appliance and chimney manufacturer instructions, using appropriate clamps or fastening methods where required. Check for correct alignment and for gas-tight sealing in accordance with local regulations before commissioning the heating appliance.

Usage recommendations

Use this flexible connector only within systems designed for DN80 flue components and follow all regional installation standards. Inspect joints periodically for wear, deformation or loose fittings, and replace the connector if damage or persistent leaks are observed. For installations involving sealed combustion appliances or where specific clearances are required, consult the appliance manufacturer or a qualified installer.
