About UFS I meant the same o-ring like the one I mention for GGTS. Its the o-ring between CT and connector again buddy
Yes Repent, it is number 10 on the drawing "GGTS Collection tank" and number 7 on the drawing "UFS Connector".

OK fellas I got it now. I had been looking to #7 on the "UFS" chart on page one and not the "UFS Connector" on page two. Silly me. Now that I am clued in I will update and republish.
OK so the Visual O-Ring guide is once again updated. Follow my sig to my blog and click on the link there.
Imeo, can you delete the hyperlinks in posts 8 and 16 because they are dead ends?

I deleted repent. Thanks again for the corrections. But I have to say that metric o-rings are not exactly the same as the us standard. I dont really know if the us o-rings will work properly

Funny that you say this Imeo because I wanted to post about this very same thing!!.
Please take heed all GG family.....
Yesterday I received my UFS from a seller in Poland. I took the UFS totally apart and removed all the o-rings to give it a good soak in hot soapy water. I wanted to replace the o-rings as I have spares that are all metric.
Let me also say that before buying my metric o-rings from McMaster-Carr I had sourced some US Standard o-rings that are in the o-ring guide (guide in my sig/blog) as being equivalent to it's counterpart in metric size.
When I received in my o-ring order I already had purchased a divider to store each different size separately. I even labeled the compartments. Yes I know, it is a sickness. When I came across the handful of US o-rings previously purchased I put them it the compartments with the metric ones. I did compare them and they "appeared" to be the same ID but in holding them up to the light side by side I could easily see a very very slight difference in the US o-rings. They are ever so slightly THICKER. I filed this away and thought I'd at least test them when the time came and decide if they were suitable. That time came last night.
So late last night I had cleaned the UFS and was watching Imeo's videos on how to take it apart and put it back together. I'm one of those aggravating guys that takes all the parts out of the box, gets the owner's manual, identifies the parts, actually reads the instructions, then files that instruction book into a 3 drawer filer that only has instruction books in it. I told you this was a sickness.
Anyway, when lubing up the parts and o-rings all was well until I tried to put the tank bottom to the assembly. There is a 14x1.5 o-ring there. I tried putting it together and found they would not mate up enough to engage the threads. I didn't force anything but went back to Imeo's video and watched that part again a few times. For Imeo in the video the parts mated together with a "click" and then he screwed them together without unnecessary force or torque. Big red flag to me. I took the o-ring off and grabbed another from the box. Sure enough, I had happened to grab the US o-ring instead of a metric one. I used the metric o-ring and the parts mated together as I had expected it to do the first time.
So....while your results may vary from mine, I am removing all US standard sizes from the PDF I created that shows the metric and their US equivalents. I did checkout the different US o-rings against their metric counterparts and in every instance the US o-ring was ever so slightly thicker.
Since we are dealing with tight tolerances, as good craftsmanship dictates, and the fact that Imeo creates all his work using the metric system of measurement it is my opinion that US o-rings will not work correctly.
Well anyway, that's my story and I'm sticking to it.

You're welcome guys. Truth be told I should have done my due diligence and tested metric against US standard on a GG product before I compiled that Metric/US Standard into a PDF.
Totally my fault and I am without excuse. I apologize to anyone who went out and bought US standard o-rings for their GG products based on the guide I published.
I remain your servant;

repent, you are totally right on this. I am glad that you did this test by your own so we all know now what is happening. Do you remember the o-rings for ceramic? They were 3/2 and some people couldnt fit them on the plastic part. When I send the 3/1,8 (0,2mm more in diameter) they fit easily. Now imagine the 14/1 o-ring. In us system the 9/16 ts 14,28mm that is 0,28mm more in diameter. Thats a lot of difference because like you said we talk about very tight tolerances on UFS.
You were very quick on your tests so I dont think that many people bought US o-rings repent. Thanks again for your big help buddy
ok, i got my package from mcmaster.. looks like i need to swap out the 18/1.5 for 17/1.5 mentioned above. I'm hoping i got this right... this is very tedious, and I am sure it is even more so for Repent.
Anyhow, i cannot find the 2/2 or 3/1.8
It is used around the ceramic for iAtty. 3/1.8 is listed in the Visual Guide, whereas 2/2 (and 3/1.8) listed in the non-Visual Guide. Has anybody found these online?
Also, which is better for the ceramic of iAtty of the following:
2/2 & 4/1.5
or
2x 3/1.8
???
Thanks in advance!

I had already ordered the 18x1.5 as well. I fit them to UFS and so far so good. I think I will hold off on getting the 17x1.5 unless some problem arises. No leaks thus far. I also could not find the 2/2 nor the 3x1.8 at McMaster-Carr which is really weird because they have everything else. Let me know if you find them somewhere. I did get some 1/8 x 1/16 for the ceramic a while ago but haven't had a reason to change them out yet. I do not know if in this case a US size would work. Perhaps someone else can speak to this?
