I kicked off a 23L FV yesterday and i have had issues trying to get the cap to seal correctly as its missing the rubber ring. i know its not 100% important but i want to see the air lock bubbling away. I have prevously tried super tightening the cap and a good smear of vasoline but that was very messy and did not work very well.
Today I tried something new - Cling flim!
Roll out about 2ft length of standard kithchen cling film, so it goes twice round the groove in the cap
Roll the length into a sausage
Pack the sausage into the groove inside the cap, i used the end of a fork to help guide it into place, dont pull it too tight as it will keep jumping out the grove.
fit the lid to the FV. I didint have to tighten it very much before the airlock started bubbling away!
