They look far too big to me. If you're talking about the 4 little vacuum pipes then I would think half that size.
I would have thought the 4mm ones.

They are nowhere near 10mm .. i thought they were like 4mm could be wrong though ...

Yes, there is an option in the advert that says he sells 4mm.

Doesn't seem to have them in stock tho...

Is this for the 4 balancing ports ? 4mm
can thread them & use grub screw or allen screws with tiny bit of liquid sealer.
If use caps worth getting little spring clamps for them so no issues of blowing off, could use small wrap ties also.
