ABSTRACT:
A fluorocarbon polymer gasket is disclosed which has been compression formed from a fluorocarbon polymer sheet heated to its gel state, cooled in its compressed state, and shaped into a gasket. The gasket so manufactured has a "living memory" thus enabling it to tend to return to its pre-compression form when exposed to elevated temperatures.
