A seal (1) or joint has an outer sheath (2) made of plastics, in particular PTFE, and a sealing core (3) made of glass fibres that preferably contains at least one additional layer made of a soft PTFE mass. The glass fibres are wound into the outer sheath (2), forming layers that if necessary alternate with the soft PTFE mass. A chemical-resistant, plastic and elastic seal (1) is thus produced that is in particular suitable for sealingly joining sealing surfaces of enamel/enamel, glass/enamel, glass/glass, metal/glass, etc. The seal may be for example designed as a flat seal for joining spherical or parts in pipe-ends, fittings or apparatus made of glass. |
