The MI-FLEX Adaptor - Ø 250mm, made from high-quality 0.6mm 316 stainless steel, ensures a seamless connection between your single wall flue system and MI-FLEX flexible flue liners. This robust adaptor, part of our MF20 MI-FLEX accessories range, is ideal for multi-fuel applications, handling temperatures up to 600°C.

Ensure a gas-tight seal using fire cement, ceramic rope, tape, or high-temperature sealant. Compliance with Building Regulations Document J is essential, and remember, no flexible flue should ever be visible outside the masonry chimney.
