Abstract
Two pipeline components (5) and (6) are sealed together by a seal comprising a U-section casing (1) and a pair of rings (2) and (3) which are surrounded at their inner diameter and at their outer end surfaces by the casing (1). Adjacent inner end surfaces (9) and (8) the rings (2) and (3) are respectively, externally and internally spherical, the inner end surface (8) being generally conical with a recess therein to receive a P.T.F.E. slider (4). A centering collar (7) is provided on the ring (3). The axes of the components (5) and (6) can be misaligned by an angle .alpha. while the seal is maintained because of relative sliding action which is permitted between the surfaces (8) and (9) and because of permitted deformation of the casing (1) which is formed of an elastic and chemically resistant material.
