Primochill FlexSX fittings are a fundamentally flawed design.
Having the length of the barb shorter than the inside width (ID) of the tube means the fitting is incapable of fully supporting the connection.
Alas, if the barb is only slightly longer than the width of the tube you are still in the danger zone; the same properties that make flexible tube attractive to us can become difficulties with regards to sealing, because the *effective* ID of the tube increases when the hose is pulled in a direction other than straight out.
In my testing with mayhems ultra-clear:
- The fitting failed to hold its end of a horizonal 500mm loop of hose - While the hose was empty!!
- The sweet, sweet, toxic green collar that lured me to this product and is supposed to tighten the fitting is woefully ineffective. It provides little or no support, and is manufactured to a dangerously loose thread tolerance considering it is Aluminium.
Preventing water leaking from the loop and turning thousands of dollars into bitter regret should be the number one priority when designing a fitting, but it seems for Primochill this is not the case, their apparent 'patch' for this shonky design is to suggest users should use "advanced" LRT tubing.
Primochill, there's a reason we go for flexible tube - why do you approach the market with a product that requires out-of-standard sizing, with a stiffer formula of material, and still sucks?
I expect some users will have used them without Issue, but you should consider yourselves lucky and use the reprieve to replace the fittings as soon as you can (please just bin them rather than selling them on, those afflicted by the need to liquid cool have enough troubles
Mods- how in humanity does my I'm_not_a_robot verification expire? You can throw scripts and cookies at me to track me across the internet, but not keep me verified to make one post if it takes longer than 45 seconds!
