The IL 152mm (6in) Length - Ø 125 Gas Vent Pipe is an essential component for naturally aspirated domestic gas-fired appliances. Boasting a twin wall insulated design, this pre-fabricated gas vent has a stellar reputation for quality and reliability, built over the past 25 years in the UK. Available in three diameter sizes—100mm, 125mm, and 150mm—this system is meticulously constructed with an aluminium liner and a zalutite outer case, separated by a 6mm air gap.

It's suitable for both internal and external installations but not recommended for condensing and positive pressure applications. It performs optimally under negative pressure and dry conditions, with flue gas temperatures not exceeding 250°C, making it an ideal choice for high-efficiency gas appliances with a draught hood or diverter.
