The 904L Mi-FLEX 125mm x 1m flexible flue liner by National Flues combines durability and versatility, making it perfect for relining masonry chimneys. Crafted from high-grade 904L stainless steel, this double-skinned flue liner boasts a smooth inner surface and a convoluted outer skin, each 0.105mm thick, ensuring both robustness and flexibility. Its unique quattrolock seam design provides an airtight seal.
Suitable for a wide range of fuels including gas, oil, coal, coke, and approved smokeless fuels, this liner meets stringent HETAS and CE standards. Installation is straightforward, but must always begin from the chimney's top, and thorough cleaning and inspection are recommended for optimal performance.
