What is the best replacement for the O ring on an iClear 16 drip tip? When I fill it I always wipe the bottom of the tip. This morning I wasn't fully awake and when I wiped it off the O ring went flying off. I looked for it, but being small and clear its a lost cause. I was already planning on getting more gear but can't until next week. So if I can't find a replacement will it start leaking? Not work as well? Work until next Friday? Thanks everyone. I love this place!
