I haven't used them yet but the fittings looks cool. It will look better after I complete the build and add a black light

Before you install it

This is a component, not an assembly — how it goes in depends on the loop it is joining. What does not change is the last step: leak test before power. Run the pump on a bench supply with the rest of the system unpowered. 24 hours is the standard, an hour is the minimum.

Custom water cooling is installed by you, at your own risk. We are not responsible for leaks, or for damage to your parts or system. If you're unsure at any step, ask before you power the loop.
