You can order it from Fischer Scientific, Cat.No. 14-178-5F.  It is only
12 feet long and costs $120!

You can also buy 50ft black latex tubing with the same specs from VWR
for $150.  Part.No. 62995-721.  I haven't used this one though.
I have used the amber variety, but its wall thickness is only 3/32" instead of
1/8" and it feels a little too flimsy.  It would be nice to hear from
someone who has used the black one...
