Seals to Minimize Leakage at Higher Pressure

Fixed and moving seals to be used in the super-pressure range, 10,000 to 100,000 psi, as classified by the author, are studied and evaluated. A general discussion of the theoretical problems in confining pressures of great magnitude precedes methods for designing seals for such pressures. A method and device for evaluating seals has been developed to provide confirmation of theories. Practical seal problems and applications are shown.
