Aluminium molds do the same thing.

Hay Patrick: Just came up with a thought. If you care to do this? Get one of your EPDM o-rings.
Get a precise measurement of the diameter and then put it in your Kitchen Freezer for a couple of
days. Then take it out and measure it again. Let us know if any shrinkage occurred and if so how much?
Thinking this could be my problem. Larry

Patrick: Thanks much for trying. Kinda surprised what happened. Will keep an eye out to see what
happens with my situation. Will have pedal pressed during next storage cycle.

Gary: When I googled about rubber doing the opposite of what we think I came up with the following:

Rubber bands behave in a manner opposite to that of most solids: They contract when heated, expand when cooled. Further, the length of a stretched rubber band does not return immediately to its original non-stretched length. These behaviors are due to the structure of rubber, being long, loose, twisted chain molecules.(Just like Mark indicated)

Wonder if Patrick's O-Rings do the same?? Larry
