Dura Flue 904 Flexible Flue Liner is arguably the best on the market. Where as most liners are made from one strip of steel folded in half creating the inner and outer liner, the folding of steel weakens the steel. Dura Flue is made from two separate strips of steel (904 inner - 316 outer) it's this unique manufacturing technique that makes Dura Flue different and makes it one of the strongest and most reliable. It also has a 30 year guarantee compared to the 20 years that most other liners offer.

The minimum length you can order on-line is 5 metres.
