Abstract

Optical measurement devices including one or more sealing assemblies are described. The sealing assemblies are configured for use at relatively high temperatures and pressures, such as temperatures over 200 degrees F. and pressures over 10,000 psi. The sealing assemblies can include a deformable seal element surrounded on each side by a backup seal element. In some examples, the deformable seal element is formed of a material selected from a group consisting of a fluoroelastomer or polytetrafluoroethylene, and the backup seal elements are formed of a material selected from a group consisting of flexible graphite or metal foil. Optionally, at least one additional seal element functioning as an extrusion barrier can be placed on the opposite side of one or both backup seal elements from the deformable seal element. The additional seal element can be formed of polyether ether ketone or flexible graphite, for example. Additional devices and assemblies are described.
