High Quality 5 inch Flexible Flue Liner (904L/904L Grade), – Multi fuel flexible flue liner made from 904L grade low carbon stainless steel – life-time manufacturer’s warranty with this product.

Please don’t confuse this product with cheaper alternatives on the market. As with all products from Flue Stock, our 316 grade flexible liner has been vigorously tested. It is made from high quality 904 grade steel, manufactured in two skins with an extremely smooth inner bore.

High Resistance To Damage:- The unique jointing system and high quality of the low carbon stainless steel gives the flue it’s high strength. With many 904 grade flue liner on the market when an average sized adult stands on the pipe and it will instantly crush down, our flexi flue pipe will withstand an adult standing on it, which is a sure test of it’s quality and strength. – Avoid fitting issues with poor quality flexi liner that crushes, bends and kinks during installation.
