Vamo O ring fix help!

[errolng]

Just got my bamboo/vamo yesterday and it has the low ohm error.
Saw the fix online but not sure where to buy the o ring of that size over here.
The US brand sells it as #60 o ring.
Not sure what to look for here as the 2 diy shops I checked only sold one size.

Bro care to eleborate more on the low ohm error ?

It drops to like 0.3 ohms so it won't allow me to vape.
It's supposedly a common error.
Found the fix just need to know where to get the o rings of that size

Zzzz looks like the solution to remove the o ring wasn't so simple... as least not for me.
Managed to pull out the centre pin but have no idea how to push it back in.
Has any1 ever done this before?
