The 316L Mi-FLEX 125mm x 44m COIL is a double-skinned flexible flue liner, expertly designed to reline masonry chimneys. Constructed with a smooth inner liner from 316L grade stainless steel, this flue liner offers robust durability at 0.105mm thickness. Its convoluted outer skin, also made of 316L stainless steel, ensures maximum protection.
Notably, the liner is created from a single strip of steel bent at 180 degrees, sealed with an Omega-Lock for a secure fit. Approved by HETAS and CE-certified, this versatile flue liner is suitable for gas, oil, coal, coke, cured dry logs, and cured dry peat. Installation is straightforward; however, ensure the liner fits the chimney, sweep the chimney, and ensure the pot is in good condition.
Maintenance is simple—sweep the chimneys serving solid fuel appliances at least once a year to maintain optimal performance.
