The Flue Adaptor - Long Tail - Ø 150 is a robust and essential component for integrating a rigid single wall flue system with MI-FLEX 316 and 904 flexible flue liners. Crafted from 0.6mm 316 stainless steel, this adaptor ensures a strong, durable connection capable of withstanding temperatures up to 600°C. It meets the UK Building Regulations Document J, which stipulates the use of a fully enclosed masonry chimney.

Perfectly suited for use with wood (under 20% moisture), smokeless coal, gas, and oil appliances, this long tail adaptor facilitates a gas-tight seal through the application of fire cement, ceramic rope, tape, or high-temperature sealant. Easy maintenance and cleaning are ensured, with sweeping recommended by a HETAS registered sweep at least twice a year for solid fuel systems.
