Anyway to fix this sort of leak?

[Rainagul]

Currently doing a quick refresh of my system with new tubing/fluid due to installing new parts.

I'm experiencing a small leak on my DDC pump with EK XRes 140 Top.

I never used to have this in the past. I noticed this after I put the new loop together earlier today. When I saw the leak the first time round I drained everything, replaced the fitting with a new one, thinking maybe the old o-ring was damaged. I also cleaned/dried the hole and made sure the fitting was placed in quite firmly.

Alas, I'm still experiencing the same thing even after new fitting. It's not a huge leak, the above photo took 1h to get to that stage. I will probably drain my system again tomorrow and try again.

Has anyone got anything I can try to see if that will solve the issue?

I left it leak testing overnight and was surprised to see this morning that only a tiny amount of liquid leaked out, so maybe it's not as bad as I first feared.

Will still get a new set of pliers at lunch and give it a good tighten for good measure.

Just given a half turn tighten with some pliers and haven't had any leaks or residue, so think I may have got it.

Will try silicon for the future if it proves to be an issue though.

thanks for the advice guys
