    from Dayton, Ohio asked:
    February 1, 2014
    I have a 20 foot liner but have changed plans and now need it to be 30-35 feet. Is there an adapter that I can purchase to connect two sections of DuraFlex together for the length I need?
    1 Answer
    It is indeed possible to connect two lengths of DuraFlex by using the DuraFlex SS Connector Adaptor for 4 inch Chimney Liner - 4DFS-FC. This component is also available in other diameters, should your liner be a different size.
