Abstract
A radial compression spring having a formed of an elastomer having a ratio of plastic strain to elastic strain that is greater than 1.5 to 1 into a hollow body having oriented wall sections that include a bend as a result of radial precompression. The spring is precompressed to overcome the compression set characteristics of the elastomer and to orient its molecular structure.
