Opie, is the silicone tubing on these resistant to the effects of freezing temps? In your "Anyone interested" thread you mention a tubing that is not affected by cold. Just curious if it on these. Thanks!
Don't know exactly what silicone tubing you are using, but I was curious about the properties of silicone tubing and so checked McMaster-Carr.
With a 3x stretch capability and an operating temperature range of -80° to +425° F, it will definitely exceed any temperatures I would be likely to encounter. I'll bet even Turk would be reluctant to venture out in the low temperature range the high purity silicone tubing is capable of.
Opie, this is a great idea! I'm going to have to save up some more quarters because I like your style.
