Our KC to TWPro Transition Adaptor - 125mm is an essential component for connecting different chimney flue systems. This adaptor is especially effective when you need to link an existing KC flue at the bottom with a TWPro system at the top. Built with dual layers of high-grade stainless steel – 304 grade on the outer and 316 grade on the inner – this adaptor promises durability and performance.
The 0.4mm thickness and compressed rockwool insulation with a 200kg/m3 density ensure optimal safety and efficiency. Fully welded for superior strength, it requires a 50mm distance to combustibles, ensuring safe installation. HETAS approved and CE marked, the adaptor meets rigorous safety and quality standards.
Please note, using a transitional adaptor will make the entire system require a 60mm distance to combustible materials. Secure your chimney system with our trusted KC to TWPro Transition Adaptor.
