The IL Adjustable Length Gas Vent Pipe, featuring a telescopic adjustment up to 457mm (18 inches) with a Ø 100mm diameter, is a precision-engineered solution for your domestic gas vent needs. Crafted with an aluminium liner and a zalutite outer casing separated by a 6mm air gap, this twin wall insulated pre-fabricated gas vent system has been a staple in UK homes for over 25 years.
