Dura Flue 5 Inch (125mm) 904 Grade Flexible Flue Liner

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

Crafted from two separate layers of premium stainless steel—904-grade for the inner layer and 316-grade for the outer—this 5" 904 flexible flue liner is designed for unparalleled strength and reliability. Unlike most liners on the market that rely on a single strip of steel folded to form both layers (a process that weakens the material), this innovative dual-layer construction ensures maximum durability and long-term performance.

Dura Flue’s unique manufacturing process, using distinct inner and outer layers, sets it apart as one of the strongest and most dependable flue liners available today. This exceptional design makes it an ideal choice for demanding installations and ensures a level of reliability you can trust.

If your stove has a 5-inch flue and you’re burning solid fuels, it’s always best to consult the manufacturer’s guidelines to determine whether a 5-inch or 6-inch flue liner is recommended for optimal performance.

This product is available in custom lengths, with a minimum order of 5 meters when purchasing online. Choose this 5" 904 flexible flue liner for a durable, high-quality solution for your chimney system.
