<p>The screw gland has a tubular part (1) with an external thread to which an adjusting screw is applied (5). A centric passing through opening has a quick release where the adjusting screw (5) at its end of the tubular part (1) is turned away has an interior lateral hemisphere concave part (7). The close and quick release part are one part, i.e. a flexible sealing employment (9) is formed, that during adjustment to the hemisphere-like concave part (7) the adjusting screw (5) is externally laterally formed and lies close to the hemispherical concave part. The ends of concave part are tapered with the adjusting screw (5) and radially surrounds and turns into the adjusting screw (5). The internal thread is, at its free end of the tubular part (1) tapered, conical or rounded, so that the free end provides a seal with its conical tapered exterior surface (10). When screwing the adjusting screw on the tubular part (1) the seal (9) is deformed both at its first final part and at its second final part after passing through radially inside in the direction of the channel (14).</p> |
