I've ordered 50 of
these which I think will do the job. They are the same material as those above and the dimensions look perfect: 13mm internal diameter x 3mm profile. These have a circular profile - not sure if yours above do - but I think they'll work!
Sounds good, let us know how you get on :thumb:
OK, the O rings are here and seem to do the job! [Edit - For anyone looking after the link in my previous post expires, they a Nitrile O rings with 13mm internal diameter and 3mm profile. (19mm external diameter)]
They don't stay on the very first bit of the plug, tight under the top ledge, because of their round (doughnut) profile, but sit just onto the very top of the plug's 'thread'. The bottom of the old-style rubbers used to reach down to the same place, so the plug (with the new seals) goes just as far into the bottle as with the old ones - I tried the old next to the new.
I've filled a bottle with water and put it upside down, shaken around and left for an hour. So far, no sign of any leaks at all!
