Flue Adapter SpiroFlex SX-TD6/8ATCB — concentric turbo 60/100 to 80/125, condensate, white

The SpiroFlex flue adapter SX-TD6/8ATCB is a concentric turbo transition designed to join concentric flue systems with inner/outer diameters 60/100 mm to larger 80/125 mm. Intended for condensing boilers and appliances that produce condensate, the adapter provides a secure path for exhaust gases while allowing condensate to drain correctly. The unit is finished in white to match typical installation aesthetics and is designed for use where a change in concentric duct size is required without compromising sealing or condensate management.

Advantages

This concentric flue adapter offers a precise mechanical fit between two different concentric duct sizes, maintaining the concentric alignment of inner and outer tubes. It is suitable for condensate-bearing systems and facilitates proper drainage to reduce the risk of trapped condensate. The white surface finish supports discreet integration into visible installations and the component is manufactured to provide consistent sealing and airflow characteristics typical of turbo concentric flue connections.

Suitable for

• Converting concentric turbo flue systems from 60/100 mm to 80/125 mm
• Condensing boilers and heating appliances that produce condensate
• Installations requiring a secure, concentric transition with condensate drainage

Key specifications

• Concentric connection: inner/outer 60/100 mm to inner/outer 80/125 mm
• Designed for turbo (forced-draught) concentric flue systems
• Suitable for condensing applications with condensate management
• Finish: white
• Material: durable flue-grade components suitable for exhaust and condensate exposure

How to use

Install the adapter by aligning the inner and outer ducts of the two concentric flue sections and sliding the adapter into place until a secure fit is achieved. Ensure that seals and clamps specified by the flue system manufacturer are used and tightened to the recommended torque to maintain airtight joints. Position the adapter so condensate can flow to the appliance’s condensate trap or drainage point; verify slope and sealing during installation. Follow local building codes and the appliance manufacturer’s flue installation instructions throughout the process.

Usage recommendations

Use only with compatible concentric turbo flue products and in systems designed for condensate handling. Inspect seals and connections after installation and during routine maintenance to ensure condensate paths remain unobstructed and joints stay airtight. When in doubt, consult the appliance manufacturer or a qualified installer to confirm compatibility and correct installation practice.
