Sorry
, but my 7/16" ID, 11/16" OD, 1/8" walled Tygon 3603 has a 1 3/8" bend radius--Primoflex can't touch it.
The only problem with that size Tygon is that no one appears to sell it by the foot; so if you really need it (and I did) the only way to get it is to buy a whole roll. And, I don't think too many people would spend $155 for 50' of tubing when they only really need 5' of it. I've still got enough tubing left for my next 5-6 water cooling projects
If you're looking for a very good, much lower cost, alternative, try the 1/2" ID, 3/4" OD MasterKleer from McMaster-Carr. When comparing price to performance, it can't be beat.
Edit: This is the second time I've posted
this old thread today, but if you really want to see what good tubing can do, take a look at the picture I posted in post #6.
