High pressure performance requirements for HPHT seals extend from 10,000 PSI in conventional wells to 20,000 PSI or higher in ultra-deepwater and high-pressure reservoirs. Seal designs incorporate anti-extrusion backup rings preventing material flow through clearance gaps under extreme pressure differentials. Groove geometries provide optimal squeeze ratios maintaining sealing force w... https://globalsealstech.com/product/rgd-rapid-gas-decompression-o-rings/
