Hose
I’ve been trying really hard to find a vacuum hose which is both the right size (38mm ID) and aesthetically pleasing, for US viewers there is Amazon’s Industrial & Scientific section which means you can buy Flex-Tube FlexStat PU Duct Hose in a rather attractive clear with black spiral, they also sell PE screw cuffs.
However in the UK this isn’t available and realistically even if it were it would be over priced, in the UK there is a safety company called Arco, they have a couple products I am going to order 2 meter samples of, but still it’s pretty pricey.
