Description
Coaxial Flue Terminal (End Cap) 60/100 mm for Gas Boilers
Protective terminal (windproof end cap) for 60/100 mm coaxial flues — an essential element of the flue system for turbocharged and condensing gas boilers with a closed combustion chamber. The terminal is installed on the outer end of the horizontal coaxial pipe, centers the inner exhaust pipe, and protects the system from foreign objects, birds, precipitation, and strong wind gusts that can cause flame failure or boiler automation malfunctions.
Key Advantages and Features:
- Heat-resistant and UV-resistant plastic: Made of durable composite polymer resistant to regular temperature fluctuations, freezing, condensate exposure, and degradation from sunlight (UV radiation).
- Wind and bird protection: The grille design with protective deflectors prevents bird nesting, leaves, and large debris from entering the flue, while minimizing the impact of side winds.
- Inner pipe centering: Internal fasteners securely hold the 60 mm diameter inner flue pipe strictly in the center of the 100 mm outer air intake pipe, ensuring stable fresh air intake.
- Ease of replacement: Allows for quick restoration of the flue system's functionality and safe operation if the original plastic terminal is damaged or aged, without needing to purchase a complete flue kit.
Compatibility and Application:
Suitable for all standard horizontal coaxial flues of 60/100 mm size (60 mm inner exhaust pipe diameter, 100 mm outer air intake pipe diameter) for turbocharged (parapet) and condensing boilers of the following brands:
- Baxi / Westen (Main Four, Fourtech, Eco Compact, Pulsar, etc.)
- Vaillant (turbOTEC, ecoTEC)
- Protherm (Gepard, Panther, Jaguar, etc.)
- Ariston (Egis, Clas, Genus, Cares)
- Ferroli (DomiProject, Fortuna, Divatech)
- Viessmann (Vitopend 100, Vitodens)
- Bosch / Buderus (Gaz 3000/4000/6000, Logamax)
- Navien, Immergas, Fondital, Biasi, Beretta and other boilers with the 60/100 mm standard.

Pro tip: When removing the old terminal and installing the new one, clean the pipe ends of carbon deposits, soot, and stuck dirt. Before fitting rubber seals or snapping the terminal into place, it is recommended to lightly apply silicone grease to the joints — this will facilitate installation, prevent damage to the O-rings, and ensure the airtight separation of exhaust and intake air flows.
