Flue pipe transition Jeremias Przejście FLEX/FLEX fi 80 FD06080

Jeremias Przejście FLEX/FLEX fi 80 is a flue pipe transition designed to connect two flexible chimney sections with a nominal internal diameter of 80 mm. Manufactured by Jeremias, this transition piece provides a stable coupling between compatible FLEX components used in exhaust and ventilation systems. It is intended for installations that route combustion gases from appliances to the chimney system while maintaining alignment and continuity between flexible liners.

Advantages

The transition ensures a secure mechanical connection between flexible flue sections, reducing the risk of misalignment and leaks at the joint. Its geometry is optimised for compatibility with 80 mm flexible liners, enabling a tight fit and consistent internal flow. Made to the manufacturer's specifications, the component supports reliable operation in domestic and light commercial exhaust applications and simplifies assembly where flexibility in routing is required.

Suitable for

• Connecting two flexible flue liners with 80 mm nominal internal diameter
• Residential gas, oil, or solid fuel appliance flue systems where flexible liners are used
• Repairing or extending existing flexible chimney runs
• Ventilation routes that require flexible-to-flexible transitions in tight or offset spaces

Key specifications

• Compatible internal diameter: 80 mm nominal
• Function: transition / coupling between flexible flue sections
• Material and construction: manufactured to match flexible liner requirements for exhaust systems (metallic construction compatible with combustion gas routing)
• Application environment: indoor residential and light commercial chimney and ventilation systems

How to use

Fit the transition between two flexible flue liners by inserting each liner end into the respective side of the transition until a snug connection is obtained. Ensure that the flexible liners are clean and free of damage at the insertion points, and that the transition is aligned with the intended flue path. Use the appropriate clamps or securing elements recommended for the flexible liners to fasten the connection and prevent displacement. Verify that the combined assembly maintains continuous internal diameter and unobstructed flow for combustion gases.

Usage recommendations

Installations should follow applicable local building codes and the appliance manufacturer's flue instructions. Inspect connections after installation and during periodic maintenance to confirm seals and fastenings remain intact. For systems handling high temperatures or corrosive by-products, select compatible flexible liners and ensure the transition material meets the required resistance and temperature ratings.
