About Dragon Flex 316 Grade Chimney Liner

Dragon Flex is produced by leading chimney company Midtec, in the heart of Wales. Midtec products are respected and widely used by HETAS and Oftec installers all over the UK. Dragon Flex liner material is imported from Germany and finished off here in the UK by skilled technicians.

 Lining a Chimney can be a costly and time-consuming exercise and something that you do not want to repeat because of a liner failing. Therefore, we refuse to sell cheap inferior liner and only offer our customers the best liner on the market but still at a fantastic price.

Formed in a completely different way than most liner, Dragon Flex has an unbreakable lock between layers which prevents it from pulling apart at all and keeps the inside super smooth for easy down drainage of condensates. This super smooth layer also helps prevent soot and tar from building up on the inside of the liner, potentially preventing blockages. We have sold most liners available on the market and feel this is up there with the best. We would rather sell this liner and not have the stress of customers phoning up a few years later because their liner has failed, and they need to buy a new one.

How to Order

• Step1: Choose a length of 5" (125mm) Dragon Flex, flexible liner using the drop-down options list at the top of the page
• Step 2: Choose one of our Italian made 5" (125mm) flue pipes, or select "No thanks"
• Step 3: Choose the MA adapter to join to your stoves flue pipe to the flexible liner. A 5" MA adapter will connect 5" flue pipe to 5" liner. Select "No thanks if not required"
• Step 4:  Select your 5" register / blanking plate kit to cut off airflow from the chimney and prevent debris from falling back down the chimney. These are made galvanised steel in a factory just a few miles from us. Select "No thanks if not required"
• Step 5: Choose a cowl for the top. The standard pot hanger cowl will be fine for most installs but the anti-down draught cowl is an option if you know you have a down draught problem. The Cowl fixes to both the chimney liner and chimney pot.  We also offer a top plate and clamp for those choosing to install that way. Again, these are quality Midtec products. Select "No thanks if none of these are required. 
• Step 6: Choose whether or not you wanted to add heat proof silicone
