7. Hydraulic seal - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_seal

   A static hydraulic seal is located in a groove and sees no movement - only sealing within its confined space, acting like a gasket. To achieve this the gasket should be under pressure. The pressure is applied by tightening of the bolts. Examples of static seals include O-rings, flange seals, and cover seals. Dynamic
