This video illustrates part of the reason we do not use plastic nozzles on our fabric ducting. The plastic nozzle is subject to an identical flame test to a Fabric Nozzle. It's our belief that the Fabric Nozzle is a safer product, it's made from the same material as the fabric duct and its the same colour. It's not pressed, snapped or glued into place, but sonic welded, so that it cannot detach. It's also impossible for the Fabric Nozzle to damage the fabric duct in the washing machine during cleaning.
