The 904L Mi-FLEX 180mm x 1m CUT LENGTH flexible flue liner is meticulously designed to offer robust and efficient performance for relining masonry chimneys. Constructed with dual-layered 904L grade stainless steel, both the smooth inner and the convoluted outer layers boast a thickness of 0.105mm, ensuring lasting durability and resistance to corrosion. The unique Quattrolock seam sealing method adds an extra layer of security, making this liner apt for use with gas, oil, coal, coke, cured dry logs, dry peat, and approved smokeless fuels.
Approved by HETAS and CE certified, this liner guarantees safety and compliance with industry standards. Installation is straightforward — always fit from the top, ensuring the arrows indicating gas flow are pointing upward.
