O Rings For Geocache Containers 5-pack
These rubber o-rings are approx. 1/2″ outer diameter & 3/8″ inner diameter, perfect to fit very tightly on our regular bison tubes and our tiny bison tubes. We recommend keeping several of these on-hand as they tend to get lost or wear out after a time, you’ll need them to keep your tubes & logs dry!
These come 5 to a pack.
