Lessee, 5m tube vs. 5cm (or .05m) tube...I'd guess something approaching 100x as
long? :) I'm guessing you meant to type something a little different there...
Anyways, by my eye, the flex-system tube OD is roughly the same as the OD of the
pneumatic nipples. I'd be worried about how painful (both physically and
mentally) it might be to attach all of those hoses and how easily they might
split under pressure. I just tried to attach one and I couldn't even get it
started, so I'm very curious how you go about doing it. Do you use a short stub
of pneumatic tubing as a sleeve coupler, or have you actually managed to cram
one of those things onto a pneumatic nipple?

| (...) Yes, the 100x length difference will give a significant balloon effect. I suppose realistically 40cm to 5cm would be a fairer comparison. Set 8868 came with a 5m bundle of pneumatic tube. The use of flex tubing in sets began with sets 8837 (...) (20 years ago, 23-May-04, to lugnet.technic)
