Learn About Stainless Flexible Chimney Liner Kits

Rock-Flex Flexible Chimney Liner Kits are installed inside a masonry chimney to quickly, affordably and safely re-line your flue without having to re-construct the entire masonry chimney. Available in a variety of grades of stainless steel, as well as a variety of shapes which provides options for the perfect installation. Customize your chimney liner kit components for your specific installation. UL 1777 listed. We back the Rock-Flex Chimney Liner Kits with a lifetime warranty to give your and your family peace of mind.

316Ti Stainless Steel Chimney Liner Kits can be used for all fuels such as wood burning stoves and inserts, coal stoves, traditional masonry fireplaces, oil burning, and gas burning appliances. Rated for temperatures of up to 2100 degrees. 316Ti liners are available in corrugated round liners as well as corrugated oval, rectangle and square shape chimney liners. Chimney flues are far from a standard size, which makes the oval, rectangle and square liners a great option when the proper size round liner will fit down your chimney. 

316L Stainless Steel Chimney Liners are very similar to the 316Ti liners with the same 2100 degree heat rating and same UL listing. Use for all fuels such as wood burning stoves and inserts, coal stoves, traditional masonry fireplaces, oil burning, gas burning appliances. The 316L liners are available in Smooth Wall and Premium Smooth Wall liner. Smooth Wall liners allow for 20% higher BTU capacity for gas appliances and a 15% higher GPH firing rate for oil appliances. Premium Smooth Wall Liners are extremely flexible and durable, with no metal memory. The Premium Smooth Wall Liners are best used for any fuel type, chimneys that are rough and jagged inside, or with chimneys that make a few bends down the chimney.

AL29-4C Flexible Chimney Liner Kits are used for venting high efficiency gas and oil burning appliances. AL29-4C is a unique alloy that is highly corrosive resistant capable of withstanding the high acidity that high efficient gas and oil burning appliances produce inside the chimney. With a temperature rating of up to 600 degrees, the AL29-4C liner is not suitable for solid fuels.

We allow you to fully customize your Rock-Flex chimney liner kit so you have the necessary parts to fully reline your unique chimney size. Various adapters, tee connectors, and bottom plates are used to make the connection to your appliance or fireplace. Choose from a variety of top plates and rain caps to seal off your existing chimney while supporting the liner.
