ABSTRACT:
A static joint in which stationary members are sealed by a gasket and wherein the gasket has a first member of elastomeric deformable material and a second member of rigid material, the deformable member having a sealing portion and a retainer portion, the rigid member being embedded within the retaining portion and of a height more than 60% of the height of the retaining portion to limit deformation of the first member. The rigid member is chemically bonded to the elastomeric member to inhibit movement or extrusion of the elastomeric material from between the rigid member and the members being sealed under heavy clamping pressure.
