316Ti Flexible Chimney Liner Only

Rock-Flex chimney liners are fabricated with 316Ti .006 stainless steel, have 7 ply seams with 10 corrugations per seam, air and water tight, and provide the best flexibility and strength to contain moisture and flue gases. Our Smooth Wall Deluxe chimney liners are fabricated with 316L .013 stainless steel and have 7 ply seams with 2 inner linings. Use our flexible chimney liners with stoves, fireplaces, inserts and more. Round flue liners are the most common type of flexible liner. In the case that you can't fit the ideal size round liner down your flue, a shaped liner is the next best choice. If you have questions, please contact us!
