A DIN 7603 defines the standards for metallic sealing rings (washers) used to create tight, static seals in mechanical assemblies. The primary purpose of a DIN 7603 sealing ring is to prevent the escape of liquids or gases from a system while simultaneously blocking the ingress of dust, dirt, and moisture.
