Copper Sealing Ring DIN 7603

The sealing ring (a washer with reduced width) is used in mechanical engineering, instrument making, and at auto service stations for vehicle repair. The ring is used in the repair of internal combustion engines, fuel systems, and hydraulics of automobiles and agricultural machinery — as a sealing gasket in detachable threaded connections.

The ring seals the assembled parts of units and components, prevents self-loosening under dynamic loads, and ensures reliable fixation of the connection. It is made of non-ferrous metals, mainly copper — this metal withstands temperatures of up to 300 degrees.

The ring is used together with cylindrical threaded fasteners of the corresponding diameter — bolts, nuts, studs, screws. Sealing rings are available in various sizes, which allows selecting a version that matches the required dimensions.
