Dura Flue 7 Inch (175mm) 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 7-inch (175mm) 904 Grade Flue Liner is designed to be one of the most durable and dependable flue liners on the market, setting a new standard for strength and reliability.

What makes Dura Flue exceptional is its innovative construction. Unlike most liners, which are manufactured from a single strip of steel folded to create both the inner and outer layers, a process that inherently weakens the material. Dura Flue is crafted from two separate layers of stainless steel. The inner layer is made from premium 904-grade stainless steel, while the outer layer is constructed from 316-grade stainless steel. This unique two-layer design ensures maximum durability and performance, even under demanding conditions.

Adding to its appeal is the impressive 30-year guarantee, a significant upgrade over the typical 20-year warranties provided by other flue liners. This extended guarantee is a testament to the liner’s superior build quality and longevity.

The minimum order length available online is 5 meters, making it easy to customise for your specific installation needs. For unparalleled strength, reliability, and peace of mind, the Dura Flue 7-inch 904 Grade Flue Liner is an outstanding choice.
