Abstract
A multilayer seal comprising a stack of rings, some being made of elastomeric material and some being made of more rigid material, such as a metal. The elastomeric and rigid rings alternate in the axial direction of the stack, and the elastomeric rings are progressively thinner in the axial direction of the stack. Each ring is preferably bonded to the next successive ring in the stack. When the seal is in place between two opposed surfaces to be sealed against fluid pressure, the thickest of the elastomeric rings is arranged nearest the higher pressure end of the opposed surfaces.
