Someone recently wrote that the above "O" rings have a 2 mm body and a 12 mm
hole. I visited my local Ace Hardware and found that they had ones that
matched that description for 59 cents each. Bring your own metric measurer,
as the sales person looked at me like I was crazy when I mentioned those
measurements and I had to measure them myself to find the ones I wanted.
