Forever Flex 304L Chimney Liner Appliance Connector Kit

Forever Flex

  • $250.00

Forever Flex is a premium chimney lining system custom made with the installer in mind.

The liner is made of 304L alloy. This is the highest quality metal available today for liner manufacturing and we use it! All components involved in venting the gas are made out of matched metal to ensure quality. Just another detail that makes this the best kit in the world. We invented the quick and easy way to install these liner kits. Our Quick Connect hose clamp system was designed by Will and Chris. This hose clamp style fastening system means no more screws, drilling, or rivets. The liner and all components are of the highest quality! The liner offers a strong 7-ply seam, which is air and water- tight. The liner has ten corrugations between each reinforced seam, offering greater flexibility. All components are designed with ease of assembly. The Quick Cap features a wire screen and a wind guard (a no-screen style and a screen with no wind guard style is also available) which installs to the top plate collar without the need for a separate storm collar. This allows for fast installation and easy chimney cleaning. Our exclusive No Sag/No Leak Top Plate has a welded collar and sloped plate. Our Quick Tee design is fabricated with a 10” long snout in addition to a secure inside removable take-off. 

Fully UL/ULC tested and listed to the UL 1777 and ULC-S640 standards by Underwriters Laboratories. In addition, Forever Flex™ offers an industry exclusive, Forever Warranty.

 Recommended for use with wood and pellet. For coal please see our 316Ti Liners

These length and price combinations represent the best deals on a per foot basis. All chimney liners are available in any length you require. However, if you need less than 50 feet it will be cheaper to size up and cut the liner to fit. We can also fabricate liners for 9, 10, 11, 12,  14, and 16 inch diameters to fit any flue. Please give us a call for custom orders to verify all information is correct as the return policy varies for custom orders.
