摘要： A sealing device for providing a fluid-tight seal when jointing different types of pipes. The sealing device comprises a sealing ring made of a resilient material are positioned in an annular groove in the outer pipe, and has a sealing portion adapted sealingly to engage an inner pipe introduced therein. A retainer ring made of a rigid or semi-rigid material cooperates with a radially inwardly extending projection of the sealing ring for retaining the sealing ring in a correct position in the groove during the introduction of the end portion of the inner pipe to a position wherein the end portion of the pipe deforms the sealing portion. The projection is positioned immediately in front of the retainer ring in the direction of introduction of the inner pipe, and the sealing portion is positioned behind the retainer ring. Preferably, the projection converges in the direction of introduction of the inner pipe so that the projection is folded over the retainer ring and presses the ring radially outwards when the projection is deformed by the inner pipe.

摘要： The invention relates to a pipe section of the type which is manufactured by means of molding and which is provided with sealing surfaces for sealingly connecting the pipe with another pipe section. An annular sealing ring is connected to the pipe near one end thereof having an inwardly projecting portion and a further portion located axially inward of the first mentioned portion relative to the end of the pipe. The sealing ring has an inwardly facing pocket and a protector for the surfaces thereof comprising an annular element in contact with the pipe which is easily removable from the pipe at the place where the pipe is to be used. The pipe is molded against the annular element during manufacturing thereof.

摘要： A sealing ring for sealing a space between two concentric sealing surfaces engageable one inside the other comprising first and second sealing portions each having a sliding surface. The sealing portions engage each other at the sliding surfaces and upon insertion one of the sealing surfaces in the other sealing surface each and to side against each other along the sliding surfaces which are preferably provided with lubricant. In the sealing ring illustrated, one of the sealing portions has a substantially conical sliding surface and the other sealing portion is connected with the first sealing portion and from that point of connection extends along the conical sliding surface so that the second sealing portion covers substantially the whole conical sliding surface in the starting position for inserting one of the sealing surfaces into the other.

摘要： A method of making an annular seal from a generally cylindrical tubular member of an elastomeric material consisting of the steps of forming a recess defined by an inwardly directed surface of revolution at one axial end of the tubular member and providing a deep annular separation in the tubular member adjacent said one axial end which extends from the outer peripheral surface of the tubular member inwardly to and terminating at a point adjacent to but short of the inner peripheral surface to provide a thin flexible sealing lip at one axial end between the annular separation and the surface of revolution whereby the mass of the body portion is at least twice the mass of the flexible sealing lip.
