The VIT-Smooth GLOSS 45°/135° Elbow - Ø 125mm is a premium single-skin flue component designed for efficient and safe connection between your appliance and the flue system. Ideal for gas, oil, and solid fuel applications with temperatures up to 600°, this elbow adds both functionality and style with its sleek gloss black powder vitreous enamel coating. It should be used as a connecting pipe and not for passing through ceilings or combustible walls.

Installation is straightforward with a friction fit joint, negating the need for sealing, although optional jointing compounds can be used for extra security. Ensure a clearance of at least 375mm from combustible materials and cover any exposed steel after cutting to prevent rusting. Routine inspection and cleaning are essential, particularly for solid fuel appliances—installing access doors at directional changes can facilitate this.

Choose the VIT-Smooth for a reliable, stylish, and durable connecting flue solution.
