A fracturing system (10) including a ring gasket (44) disposed between a fracturing tree (20, 24) and a wellhead component (30) is provided. In one embodiment, the ring gasket includes multiple sealing stages (56, 58) that seal against grooves (46, 48) in the fracturing tree and the wellhead component. The ring gasket may also include one or more recesses (68) between the sealing stages. In some embodiments, the ring gasket has a configuration that reduces gasket setting load and increases flange separation load compared to other gaskets used in fracturing operations. And in some embodiments, the system enables monitoring (84) of gasket sealing integrity, even during fracturing operations. Additional systems, devices, and methods are also disclosed. |
