The invention relates to a seal of parts moveable relative to one another of high-pressure devices for liquid media, comprising a high-pressure container, into the opening of which the moveable part and, coaxially around this part toward the high-pressure side, a sleeve project, and a support ring on the front exterior area of the projecting sleeve bears against the interior surface of the opening of the high-pressure container and again st a ring. In order to avoid as far as possible the wear and the material abrasion often i n individual places in the contact area between pressure container and support ring with repeated compressive load and to increase the service life of the seal of high-pressu re devices in this manner, it is provided according to the invention that at least the exterior surface of the support ring and/or at least the interior surface of the opening of the high-pressure container, which surface bears against the support ring or the sealant, has at least one coating applied according to a PVD (Physical Vapor Deposition) method, and/o r a CVD (Chemical Vapor Deposition) method, and/or in particular a PACVD (Plasma- Assisted Chemical Vapor Deposition) method.
