I purchased this new 2 months ago intending to use it as an O-ring for a pressure tank, but it did not fit the dimensions, so I am selling it. I only test-fitted it to the tank, which has no oil. Would this be suitable for someone looking for an O-ring of the same dimensions, or considering repurposing it?

Thank you.
