The Screw-FIX Flex Joiner - Ø 100 is an indispensable accessory for anyone installing or extending a flexible flue liner system. Specifically designed for seamless integration with MI-FLEX 316 and 904 multi-fuel flexible flue liners, this joiner ensures a secure, airtight connection. An essential component for creating a full chimney system, it complies with Building Regulations Document J, ensuring your flue liner is safely enclosed within a masonry chimney.

The joiner's robust design ensures longevity and reliable performance, making it a great choice for both residential and commercial installations. Regular maintenance of the chimney system, including sweeping at least once a year (twice if using solid fuel), ensures long-term efficiency and safety.
