The Screw-FIX Long Tail Adaptor Ø 150 is an essential component for connecting rigid single wall flue systems to MI-FLEX 316 and 904 flexible flue liners, ensuring a seamless chimney system. This 0.6mm 316 stainless steel adaptor excels in toughness and durability, making it suitable for appliances operating up to 600°C. It is meticulously designed to comply with Building Regulations Document J, which mandates that a flexible flue liner must be completely enclosed inside a masonry chimney.

This versatile adaptor accommodates fuels such as wood (below 20% moisture), smokeless coal, gas, and oil, providing a safe and efficient solution for your chimney needs. Bottom fixings facilitate the secure transition from the rigid flue to the flexible liner, ensuring no flex is visible while achieving a gas-tight seal using fire cement, ceramic rope, tape, or high-temperature sealant. Regular maintenance and sweeping by a competent person are crucial, especially for solid fuel appliances, to uphold the integrity and efficiency of the chimney system.
