The Bolted MI-FLEX Adaptor - Ø 100 is crafted from high-quality 0.6mm 316 stainless steel, designed to provide a seamless and secure connection between rigid single wall flue systems and MI-FLEX flexible flue liners of the same diameter. Ideal for multi-fuel applications, this adaptor ensures compatibility with appliances burning wood (with less than 20% moisture), smokeless coal, gas, and oil. It is essential that the adaptor is installed within a masonry chimney, complying with Building Regulations Document J, to maintain safety and efficiency.
