EK compression fitting torque

threedee · 22 Jan 2013 at 10:51

Well, yesterday i built my first test loop out of the case.
Everything held up, no leaks...however...

How tight i must screw in EK compression fittings ? When i need to tweak the layout its near impossible to unscrew compression ring without unscrewing the whole fitting. Tubing is XSPC 7/16-5/8 (https://www.overclockers.co.uk/showproduct.php?prodid=WC-031-XS) and its well sticky on the outside.

At this point i'm afraid i may strip threads on acetal cpu block(xspc raystorm) and ek pump top res (d5 x-res 140).

Any tips on dealing with this ?

@panyan: look at this (one of yours):

I cant tighten them this much. And it still unscrews when i try to take the ring off.

Here's mine:

And i cant undo it by hand anymore.

The new tubing is quite sticky on the outside. I suspect that this is causing the "problem" with needing so much force to unscrew compression ring.

Is there a way to un-sticky-fy the tubing ?

That explains gap. Doesn't explain excessive force needed to unscrew compression ring.
Will still need to come up with some sort of strap wrench to hold lower part from unscrewing.

Been reading on the stickiness of tubing, info very scarce (in watercooling context).

I decided to get small long nosed mole grips to help me keep lower part of the fitting.
So far found some 120mm long grips that open to 24mm, which is 3mm over whats needed.
