The VIT-Smooth GLOSS Increaser Ø 125-150mm is a premium connecting pipe designed for gas, oil, and solid fuel appliances, tolerating temperatures up to 600°C. This single skin flue system, crafted from zero carbon steel with a durable powder vitreous enamel coating, ensures longevity and reliability. Ideal for connecting appliances to your Flue Liner, Chimney Stack, or Twin Wall Flue System, it should not be used to pass through ceilings or combustible walls.

Proper installation requires adherence to safety protocols, ensuring no part of the VIT-Smooth is within 375mm of combustible materials. Friction-fit joints eliminate the need for sealing but can be made more secure with jointing compounds. Regular maintenance, particularly for solid fuel systems, involves installing access doors for cleaning.

Trust VIT-Smooth for a seamless, efficient flue connection.
