Connects 100mm (4 inch) flue liner to 80mm (3 inch) black stove pipe at the bottom of the chimney stack.
Made from 316 grade stainless steel.
Connect the bottom of the flue liner to the threaded end of the adaptor, by screwing the adaptor on to the flue liner as you would an ordinary nut and bolt. Seal the joint with either fire cement or high temperature silicone sealant. You can now connect the adaptor to your connecting stove pipe using fire cement or high temperature silicone sealant.
