There was a list of o-ring sizes here but honestly some of those don't make any sense.

Comparing the unstretched spares that came with mine, to others I had around I ordered SKU 4616906 (14x1) for the outer seal on the top cap, SKU 4616910 (9x1) for the inner on the top cap, and SKU 4616913 (6x1) for inside the chimney.

Won't have them in hand until mid next week though, I do know that both my spares for the top cap are all shredded and am currently using a SKU 1536603(13x1) on the outer there - it seems to be working well enough and the control looser.

Almost forgot to say, I find the white o-rings here to be a hair thicker than 1mm if it is 1mm thick, I'm expecting the ones I ordered to (fail and) fit tighter than the originals that came with it. If you are patient I'll let you know how it all turns out.

SKU 4616910 (9x1) is too small, needs 10x1. SKU 2066600 or SKU 4616909. I had fit a 8x1 inside the spare, and didn't add 1mm twice to the outer diameter... d'oh.

14x1 and 6x1 I mentioned works good.

7x1 would possibly work for the inner one too, at least that is what is in the spares for the SXK skyline. 14x1 is also working good for the missing deck o-ring for the jfc on the SXK.

14x1 et 6x1 que j'ai mentionné fonctionne bien.
7x1 pourrait également fonctionner pour l'intérieur, au moins c'est ce qui se trouve dans les pièces de rechange pour l'horizon SXK. 14x1 fonctionne également bien pour le joint torique du deck manquant pour le jfc sur le SXK.


Un très Grand merci pour vos réponses ;)

I can't speak for the o-rings available on Fasttech but I can speak from experience on the compatibility of "higher-grade" NBR/Nitrile/Buna and FKM/Viton o-rings you'll find elsewhere. You may have noticed that the o-rings supplied with the tank are very soft, the authentic has a shore (hardness) of 40 and it looks like Coppervape cloned that aspect too.

You can certainly just use a shore of 70 or 75 for most of the o-rings but not in the top cap (liquid flow control piece) where if you were to replace with o-rings with the exact same dimensions in shore 70 or 75 you will really struggle or even find it impossible to operate the liquid flow control.

For the outer top cap o-ring you can stretch a smaller shore 70/75 one to fit but I wouldn't go smaller than 10mm (Outer Diameter) as that is right on the limit of making a seal.
However, for the inner top cap o-ring you can't use this trick and will need to locate shore 40 or 50 o-rings in the correct size. I couldn't find FKM/Viton at this spec and size but NBR 50 (Nitrile) can be sourced with some effort, where they'll probably be quoting just the inner diameter and cross section (thickness).

Here's my list of o-rings, as tested with one exception, I also don't understand how that German list was compiled:

Outer Diameter(mm) x Inner Diameter(mm) x Cross Section(mm)
===============================================
19x17x1* Airflow ring (19.5mm is too big, 19mm works)
18x15x1.5 Glass (x2)
14x12x1 Base internal (between deck and base, unscrew 510 pin first)
13.5x11.5x1 Deck external (sits around the deck, might be 13mm, 14mm works but might slide at first)
13x11x1 Outer top cap/JFC (14mmx12mmx1mm shore 50 works well)
10x8x1 Inner top cap/JFC (must be shore 40/50)
6x4x1 Chimney

I recommend FKM 75 o-rings between the deck and base due to the durability of FKM and the potential damage to the posts when unscrewing to replace.
