stained tubing..

[Marci]

OK... starting to receive info from SaintGobain's Tech Dept... and word at the moment is that R3603 Tygon is NOT the tubing we should be using... they're still working thru the datasheets to find the perfect tubing for our purposes, but they've already stated that R3603 effectively isn't it, and that with the properties of our typical coolants, yes, it will cloud/stain over time. Adding ANYTHING which contains Glycol will worsen / speed up the staining.

Bear with me - more info as I get it...

Tygon 2000 series looks interesting... but dang expensive $5 a foot.
Maybe I shud bite the bullet and buy a PA120.3 and whichever Tygon formula ends up being the most compatiable with the tax return.
