Very nice 90-degree rotary fitting for 1/2" hoses with an inside diameter of 13 millimetres.
The thread is G1/4 and is therefore suitable for most water blocks, reservoirs and etc.
Thanks to the 90-degree angle, you can also place a water block in difficult-to-reach places in your system, without kinking your hoses!
And not only that! The fitting can also rotate in any direction!
With these fittings, you can use a hose clamp to be on the safe side (recommended).
You slide your hose over the fitting and by using the hose clamp, you clamp the hose firmly to the fitting.
