The Screw-FIX Adaptor to SW, 1mm - Ø 175mm is an essential component for anyone installing or upgrading their chimney system. Perfectly designed for use with MI-FLEX 316 and 904 flexible flue liners, this adaptor provides a reliable and secure connection between rigid single wall flue systems and flexible liners of the same diameter. Constructed from durable 1mm 316 stainless steel, it can withstand temperatures of up to 600°C, making it suitable for use with wood (<20% moisture), smokeless coal, gas, and oil appliances.

In compliance with Building Regulations Document J, this adaptor ensures safety and performance by requiring that the flexible flue liner is fully enclosed within a masonry chimney, avoiding non-masonry enclosures.
