Clutch Fluid Pipe

[Tustin <tustin@xmission.com>]

Does anybody know what the purpose of the spirals are for in the master 
cylinder-to-slave cylinder pipe?  And, are they important?  My '67 had 
three spirals in it, while I looked in my friend's '70, which only has one. 
 I replaced that original pipe this weekend with one that I formed, but it 
was too short to put any spirals in and I'm wondering if that's something I 
need to worry about.  Thanks in advance!
