Problem with EK Fittings (First time builder)

So I got all my parts together and assembled the build. Tubing's all that's left. However, I ran into some problems while experimenting with the fittings.

I tried test fitting some tubes, (I have 16mm hardline EK tubes and fittings) but the tube doesn't seem to go all the way in, and after screwing in the compression, I can still pull the tube out quite easily. I did a little research and indeed the tube has to go all the way in (after chamfering and sanding the tube), past the o-ring.

With that technique, I managed to push the tube all the way in, but it still requires an excessive amount of force which there's no way I'll be able to do in my case. Even after a few tries, I still can't get the hang of it.

Any suggestions?


Or should I just try other fittings like this one on Jayz video:

He managed to fit the tube fairly easily.

Wet the tube and O rings before you slide it in. And yes, it takes some force to get it in. And pulling it out will always be easier than getting it in. Hardtube isn't as secured as softtube.

Yeah, but if you'd look at Jay's video (forward to 7:45), there's like no effort sliding in the tube. I didn't know the EK fittings would be so much tighter. Makes the build a lot harder for me.

But ye, I somehow managed to fit a tube with a 90 degree bend (using fittings) from one port of the loop to another. However the other tube from the 90 degree bend is not perfectly straight, but only every so slightly. Do you think this is fine?

You do the assembly in the case and with the motherboard, about which I dream!

Do you have more photos?

Also not sure how tight I should screw in my EK Velocity block. Should I screw it all the way in? Here's a pic:

I do I will upload more later when I finish the build. Hopefully tomorrow

EDIT:
Do you plan on building the same build? What angles do you need to see? Here are a few.

It's becoming a much bigger project than I hope it would be. The tube routing has become a mess I didn't know how I managed to arrive at cpu to radiator routing. Should be a simple 90 degree bend (which I've done but decided not to use). It's a pain to redo the routing since the EK fittings are just so hard to build with.

Screw it in until it is quite tight to the CPU. Give the block a wiggle/twist. If you can move it, tighten it a little more. The goal is that your cant move it with normal force of your hand.

If the same as Supremacy EVO, then you need to keep screwing until the screw bottoms out.

Although I used bitspower fittings, I relate - it took a lot of pressure to get the tube into the fittings the first time. But in the end that's good because it will be that much more secure. The o rings will loosen a bit over time, so if you're having a really hard time with it, maybe pop the o rings out of the fittings and just put them over the tube overnight or something and maybe it will make assembly a little easier.

I think wetting the o-rings is probably the best approach. Even with flexible tubing it can be difficult to get the tube over the fittings and I have had to resort to KY to get the tubes in place.

Only two ports left for the build. Right now I just want to finish the build with no leaks. Don't care that much anymore about how it looks as taking it apart is a pain for a 1-2mm adjustment. Next time around I'll make sure I'll play around with different fittings and see which I'm comfortable with.
