A composite sliding gasket (7) for joints of high- pressure pipes is basically formed by a rubber part (9) and by a rigid ring (8) - having the function of flange - that is designed to draw the gasket (7) itself from a resting position or seat (10) to a working position or seat (11) by an external pipe or hole (5) that is axially fitted on an internal pipe or barbed fitting (4). Compression of the rubber part (9) of the gasket (7), which guarantees fluid tightness, is obtained thanks to the presence of a purposely provided conical area (12) pre-arranged on the barbed fitting (4) between said resting seat (10) and said working seat (11) - Said gasket (7) is basically constituted by a rubber ring (9) fixedly coupled to a coaxial flange made of rigid material (8) of plastic or metal or some other suitable material, said gasket (7) being designed to seal a coupling with play between the hollow shaft or internal pipe (4) and the hole (5) within which a pressurized fluid can flow. |
