316 Flue Liner

316 Flue Liner is a flexible twin-wall chimney liner designed for relining existing masonry chimneys. Made from corrosion-resistant 316L stainless steel on both the inner and outer skins, it offers a durable and flexible solution for wood-burning and multi-fuel stove installations.

Its corrugated outer skin helps provide crush resistance during fitting, while the smooth inner skin supports better flue gas flow, improved condensate drainage, and easier sweeping over time. This makes it a practical choice for homeowners and installers looking for a dependable liner that is easier to fit and maintain.

This 316 flexible flue liner is suitable for use with seasoned wood and multi-fuel appliances, including wood-burning stoves, multi-fuel stoves, and open fires installed into suitable masonry chimneys. It is not suitable for smokeless fuel. For harsher operating conditions, including slumbering use, a 904L flue liner may be a better option.

A nose cone is included in the fitting kit to simplify and make installation more efficient.

Important: This liner is not suitable for smokeless fuel.
