Dura Flue 7 Inch (175mm) 316 Grade Flexible Flue Liner

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

This 7-inch (175mm) flue liner is engineered for exceptional durability and reliability, setting a new standard in the market. Manufactured from two separate strips of premium 316-grade stainless steel, it eliminates the structural vulnerabilities found in traditional liners. Most flue liners use a single strip of steel folded to form both the inner and outer layers, which can weaken the material. However, this advanced two-strip construction ensures superior strength and resilience, making it one of the most robust flexible flue liners available.

With an extended 15-year guarantee, this liner outperforms the typical 10-year warranties offered by many competitors, giving you greater confidence in its long-term reliability.

This liner is available in custom lengths, starting at a minimum of 5 meters, to suit a variety of installation requirements. Choose this 316-grade flue liner for unmatched performance and peace of mind.
