Vaillant 80/125mm 45° Flue Bends Pack of 2 | 303211 | White PP

Description

The Vaillant 80/125mm 45° Flue Bends are genuine concentric air/flue components supplied as a pack of two. Designed for use with compatible Vaillant ecoTEC commercial boiler installations, they allow a horizontal or vertical 80/125mm flue run to change direction cleanly around structural obstacles while maintaining a neat, professional finish.

Manufactured in durable white polypropylene (PP), these 45° bends integrate with the Vaillant 80/125mm concentric flue system. They are particularly useful where a direct flue route is impractical, helping installers achieve compliant routing without unnecessary complexity.
