So I took the 0-ring off of my my flask a few years ago to clean it and now it leaks. I can't figure out how to get on on correctly. I only got a few months out of it.

You should write to them. They are an amazing company. I'll bet they'll at least send instructions on getting it back together properly.

  1. they all have manuals on the Zojirushi site
  2. A thin coat of food safe silicone grease helps o-rings seat correctly in their channel. I use it on more things then I imagined, for example its the best product to use on the silicone seals on pressure cookers.

I rings need a certain amount of tension to work properly. If it’s older it might have just stretched out too much when you took it off and no longer be keeping a seal. I’d contact them and ask for a replacement o ring. Or just measure the dimensions and get a replacement.
