Technic pneumatic tubing

I just measured two pieces from set #8455
black: ID= 0.076" OD= 0.159" grey: ID= 0.072" OD= 0.161"
I also measured a stem on a pneumatic cylinder:
OD = 0.128"
I found that the tubing used for fuel lines in R/C airplanes makes a decent substitute: ID= 0.077", OD= 0.174". The only potential problem is that fuel line tubing is made from a more pliable substance (neoprene I believe) so under pressure it tends to expand a little more than the original Lego tubing.

It's a Danish company - they probably use something in Metric measures :-)
