6 Inch Chimney Flex Liner 

Chimney Liners create a barrier between your chimney walls and the flue and thus help to insulate and protect your existing chimney. They are designed to carry smoke and fumes up your flue liner instead of releasing them directly into the chimney chamber. The easiest type of liner to work with are the Flexible chimney liners. This type of liner has a flexible tube that connects to your fireplace or wood stove and runs the entire length of your chimney up to the termination. 

Chimney liners help increase the efficiency of your appliance by allowing better air flow and enhancing heat retention. They also help reduce the amount of condensation that is formed through the smoke during the combustion process, thus making it harder for creosote to form. This also helps reduce the risks of a chimney fire.

Chimney Liner Kits come with flexible pipe to work with nearly any Chimney Flu.
