ED rubber ring according to DIN 3869 are used as axially static soft seals in combination with threaded elements. Common applications include construction machinery, hydraulic presses, injection machines, fittings, hydraulic valves, and threaded tube connections in industry in general.
The special shape of ED rubber ring enables them to be used in high-pressure applications, compensate for manufacturing tolerances, and provide reliable sealing action.
