The Unico System supply tubes are available in 50mm inside diameter and 89mm outside diameter. They are often referred to as Sound Attenuator due to the sound deadening properties of the duct. The tube core is made with nylon, which is then wrapped with insulation and finally wrapped with an outer vapor barrier to stop moisture and also to reduce thermal losses.
