ABSTRACT:
A seal for a cylindrical article and having two sealing members which coact to form the seal. Each sealing member has a resiliently flexible body which is connected to a rigid support at two spaced positions around the body. An intermediate portion of the body is resiliently flexible outwards between the two spaced positions while two body end portions extending beyond the spaced positions are caused to resiliently flex inwards. Alternatively, outward flexing of the end portions is accompanied by inward flexing of the intermediate portion. The change in shape caused by this flexibility enables the seal to be used upon a range of different diameters of articles.
