The 150mm (6") MI-FLEX Rain Cap is an essential chimney accessory designed to protect flexible flue liner systems from rainwater ingress. Manufactured from high-quality 316L stainless steel, this durable rain cap fits to the top of the chimney stack to help prevent water entering the flue, reducing the risk of moisture damage and improving the longevity of your chimney system. Designed for use with MI-FLEX 316 and 904 flexible flue liners, it forms part of a complete, high-performance chimney installation.

Ideal for wood burning, multi-fuel, gas and oil appliances, the 150mm MI-FLEX Rain Cap must be used in conjunction with a compatible top plate and clamp, with no insert required during installation. By preventing excess rainwater from entering the flue, it helps protect appliances that do not feature a condensate drain while maintaining efficient flue performance. Manufactured to the BS EN 1856-2 T600 standard and approved by HETAS and CE, it offers dependable performance for both domestic and commercial chimney systems.

Built to withstand the demands of year-round outdoor exposure, the 150mm (6") Rain Cap is corrosion-resistant and suitable for operating temperatures of up to 600°C (T600). Whether you're installing a new flexible flue liner or replacing an existing terminal, this stainless steel rain cap provides a simple, effective and long-lasting solution for protecting your chimney from the elements.
