A seal of single or multiple plies and/or single or multiple convolution regions features inflection regions to arrest or reduce bending stress in the seal's acute bend regions and/or ply deformations on non-pressure-facing plies. Additionally, there is disclosed the combined use of multiple-ply seals incorporating the inflection regions in each ply and deformations on non-pressure-facing plies.

[ What is claimed is:] [1.]1. A seal for sealing when in an installed compressed state comprising:a convolution region having a curved region and a pair of sidewall regions;a pair of leg regions, each leg region at a free end having a leg termination region;a pair of acute bend regions, each said acute bend region connecting one sidewall region to one said leg region, respectively; anda pair of leg inflection regions, each said leg inflection region disposed on said leg region, respectively,wherein each said leg inflection region and each said adjacent sidewall region define a gap therebetween sized so that said leg inflection region contacts said adjacent sidewall region when the seal is in the installed compressed state.
