Dura Flue 5 Inch (125mm) 316 Grade Flexible Flue Liner Pack

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

Crafted from two individual layers of premium 316 stainless steel, this 5" flexible flue liner is a standout choice for durability and performance. Unlike many liners on the market that rely on a single folded strip of steel to form both the inner and outer layers, this innovative design eliminates the structural weaknesses caused by folding. The result is a significantly stronger and more dependable flue liner, backed by an extended guarantee for your peace of mind.

If you plan to burn coal, a 6-inch flue liner is essential for safe operation. However, for those using a DEFRA-approved wood-burning stove, a 5-inch liner is perfectly suited to meet the requirements.

Our 316 stainless steel flexible flue liner is available in custom lengths starting at a minimum of 5 meters, allowing you to tailor it to your installation needs. With its advanced construction and superior reliability, this flue liner offers unparalleled performance for your heating system.
