<p>The seal consists of a core (2) in the form of a plate with at least one aperture (3) for a fluid to pass through, at least one elastomer strip (7) and a ribbed metal ring (10) to provide a seal round the aperture(s), and locking projections (8). At least one of the locking projections (8) is in the form of a boss projecting from the core, designed to be embedded in a layer of filling material (9) connected to the elastomer strip (7). The core (2) of the seal can be made from a single or double metal panel, with the locking projections (8) protruding from both faces and made in the shape of rings with their sides lying perpendicular to the core's surface.</p> |
