The Ø 200 25mm Offset Internal Clay Adaptor - Ø 150 is designed specifically for situations where a chimney stack has an existing clay liner and a chimney flue liner is not being installed. Crafted from 1mm thick stainless steel grade 316, this adaptor provides durability and longevity. The clay end of the adaptor is tapered to ensure a snug fit inside the clay liner, which is essential as clay liners are rarely perfectly symmetrical.

For a secure and airtight connection, use Fire Cement and Fire Rope around the clay liner. Additionally, stainless steel screws should be used to prevent corrosion, securing the adaptor effectively into place. The single wall pipe can then be placed over the adaptor's spigot and sealed with Fire Cement and/or Fire Rope for optimal safety and performance.
