Trouble sourcing o-rings to attach A7 mini to VMOD

[onem0hit]

"smilee" posted a small guide almost a year ago mentioning the o rings necessary to connect the A7/A7 mini to a VMOD, but I can't seem to find metric o rings anywhere. These are the instructions:


A7 screwed to 510-510 adapter with center air hole, side air holes I made myself but not above thread, but on the bottom of the adapter cup (exactly where vmod gives the juice)

Between the adapter and a7 is a 5x1 O-ring,
and on connector few another from the top:
9x1.5
9x1
9x1
8x1

I'm just wondering where people bought these and hopefully got them shipped to the US. Do hardware stores tend to carry small metric o rings?

I decided to just order online. I found a site that sells o-rings in all size individually and has flat rate shipping ($5 to CONUS). I assume local stores around here would only have SAE/American equivalent sizes and its just easier to use metric o-rings.

I use the o-rings off of a stardust drip tip. The are just the right size.
