A static elastomeric joint, has an elastomeric element in a cavity formed between two stops on an upper surface of a support. When the element is compressed the stops prevent it being squashed. Independent claims are included for the following: (a) The above joint where the element has a fluid tight rim whose peak is taller than the two stops; (b) As (a) with two further stops and a second elastomeric element on an opposite surface of the support; (c) The above joint where the element is polymeric and is 0.05 - 1.75 mm thick; (d) As (a) where the element is less than 1 mm thick and polymerized on the support; (e) As (d) where polymerisation is by condensation vulcanization, ion addition, ion exchange addition or IR or UV radiation. The support has a layer of non-woven material, fabric, polymer, metal reinforced rubber, composite, graphite, cation exchange resin or gas diffusion material. The element is 80% compressible. (e) Forming a joint as (a) where the support is of rubber and by injecting polymer into a cavity formed by a two part mould; and (f) Forming a joint as in (d). Preferred Features: The element has a triangular, polygonal, semi-oval, semi-elliptical or frustoconical cross-section and may be hollow.
