Our liner packs provide you with everything you’ll need to fit and connect your liner with your stove. Our liner packs includes the flexible flue liner, rigid to flex flue adaptor to connect the flexible flue liner to the stove pipe and a pot hanger rain cap, acting as a bird guard, cowl and supports the liner from chimney pot. The 7 inch (180mm) 904 grade flue liner is one of the most reliable and strongest flue liners on the market. This liner is made from two separate strips of stainless steel (904 inner and 316 outer), where as most other liners are made from a single strip of steel which is folded to create the inner and outer layer. By folding the steel you weaken it and as this doesn’t happen when the Dura Flue is been made it is stronger liner. It also comes with a 30 year guarantee compared to the 20 years that most other liners offer.
