Problems with EK-ACF fittings

[DavidMO]

I have recently purchased a ekwb water loop and started to assemble it and came to a standstill with the Ek-acf fittings. They are basic compression fittings and I have a total of 8 of them, with 5 of them stuck. They came in the package already assembled and I can not take 5 of 8 of them apart. The three that did come apart I just screwed them into the blocks and unscrewed the black ring, but for the ones that are stuck they seem to not want to separate from the inside.

How are you trying to separate them? With the allen key?

Also, EK fittings are crap, you should use bitspower instead if you want the least chance of leaks.

Two allen keys came with my entire order - the one to tighten/loosen the caps for the gpu block, and the one to tighten the screws for installing the gpu and backplate.

The inside of the fittings have notches for you to insert an allen key, you can use that to take them apart too.

All you need to do is grip the outer piece with your hand and use the key to turn the inner piece.

This is the only allen key that came with the whole thing, but it does not seem to fit.

Looks like you need to buy a bigger one.

Do you think I can just go to a hardware store and bring one of the fittings with me to get one that fits?

I found an allen wrench that worked. Thank you so much for the help!
