The TWPro GREY - Tee Cap Ø 125 is an essential component for your chimney flue system, designed specifically to cap off the bottom or unused end of a 90/135 tee. Ideal for use with solid fuel and gas/oil appliances such as woodstoves, gas coal effect fires, and boilers, this tee cap boasts exceptional durability and efficiency. Constructed from high-quality materials, the outer skin features 304 grade stainless steel at 0.4mm thickness, while the inner skin is made from 316 grade stainless steel at the same thickness.
Enhanced insulation is provided by compressed rockwool, offering a density of 200kg/m³. The assembly is fully welded for maximum strength, and it meets the stringent EN1856-1 standard, holding both T600 and T200 designations.
