Dura Flue 6 Inch (150mm) 904 Grade Flexible Flue Liner

Our flue liner packs include a stainless steel hot hanging cowl and a premium flexible liner adaptor.

The Dura Flue 904 Flexible Flue Liner stands out as one of the most advanced and durable liners available today. Unlike standard flue liners, which are made from a single folded strip of steel that forms both the inner and outer layers compromising the material's strength. Dura Flue uses an innovative design with two separate layers of steel. The inner layer is constructed from robust 904-grade stainless steel, while the outer layer is made from durable 316-grade stainless steel. This unique manufacturing method eliminates the weaknesses caused by folding, resulting in a liner that is exceptionally strong and reliable.

With a remarkable 30-year guarantee, Dura Flue far outlasts the typical 20-year warranties offered by other liners, providing you with unmatched peace of mind and longevity.

This premium flue liner is available for purchase in custom lengths, with a minimum online order of 5 meters. For strength, reliability, and superior performance, the Dura Flue 904 Flexible Flue Liner is the perfect choice for your chimney system.
