Hello,
First I would like to point out that I checked the forum, but I haven't found really conclusive answers.
I own an Ataman AP16. I fill it with a Hills mk5 and it works great. I was using the "threaded" probe and I had no leaks.
Last week, I received my new Gk1 v3 and it comes with a quick disconnect coupling. My Hills mk5 doesn't come with this, so I ordered one.
My AP16 came with a quick coupling male probe, and it seems to seal fine with the Hills female quick disconnect.
However, it doesn't seem to work with the Gk1 probe.
Let me show you - I attached pictures.
Somehow I feel like the "retaining" lip of the Gk1 (steel) is shorter than the Ap16 (brass), and so with the Gk1 probe there's a bit of "give" and it doesn't seal. If I apply pressure on the Gk1 probe it seems to seal better, but I wouldn't bet 300 bar on this
Another thing - notice the green o-rings in the female fitting - before and after coupling it with either probes - the o-rings seem to be moving out of place, and I am wondering if it's missing a smaller o-ring at the very back to keep the stack "in compression".
I'm a bit confused, and I don't seem to find a standard or norm to Google for. Dimensions seem to be arbitrary - is there any support material I could use to order the right parts? Ideally, I'd like to be able to swap probes without screwing / unscrewing.
Thanks!
The "retaining lips" seem to be of different size... So the Gk1 doesn't go as far in the female fitting maybe?
The fitting before attaching anything to it. Notice the green o-rings are correctly placed.
The fitting after attaching either the Gk1 probe or the Ap16 probe. Notice how the o-rings seem to have moved / twisted...
All parts, side by side, maybe you can spot that I'm doing something very obviously silly?
