A sealing profile for embedding in a moulded part made of curable material. Spalling observed in practice, which occur, in particular, at corners of tubbings in the area with an integrated seal, can be effectively prevented or at least reduced by using a sealing profile where the flanks of the profile base, which is embedded within the moulded part, e.g., concrete tubbing, merge with rounded portions or chamfers into the profile base face. In addition, the at least one anchoring foot is located within the profile base face and thus outside the area of the rounded portions.

Provided is a gasket mounting structure capable of preventing a gasket from being mounted in a wrong direction. The gasket mounting structure is configured such that, when a jig 200 is inserted into a gasket 100 from a large-diameter inner peripheral surface portion 124 side, a small-diameter outer peripheral surface portion 210 is press-fitted into an inner peripheral surface of a seal projection 122 to result in a state in which the gasket 100 is held by the jig 200 and, when the jig 200 is inserted into the gasket 100 from a small-diameter inner peripheral surface portion 123 side, the small-diameter outer peripheral surface portion 210 does not reach a position at which the small-diameter outer peripheral surface portion 210 can come into contact with the seal projection 122.

A gasket assembly is provided having a ring seal (100) and a ring joint gasket (12). The ring seal (100) has an annular sealing body (102) and an annular outer seal portion (106) disposed on and defining an outer edge of the annular sealing body (102). An annular inner seal portion (108) is disposed on and defines an inner edge of the annular sealing body (102). A central bore (104) is defined by an annular surface (110) of the annular inner seal portion (108). The ring joint gasket (12) has an inner surface (13) that engages the annular outer seal portion (106) of the ring seal (100), wherein the ring joint gasket is insertable into a flange of a ring-type joint.

A flanged fitting includes an annular fitting flange having an annular end face. A glass liner lines a radially inner annular portion of the annular end face of the annular fitting flange. A radially outer annular portion of the annular end face of the annular fitting flange is free from the glass liner. The radially inner annular portion and the radially outer annular portion of the annular end face of the annular fitting flange define an annular gasket abutment face configured to seat a gasket thereon. An annular gasket includes an annular gasket layer. The annular gasket layer includes a radially inner annular gasket segment including a first material suitable for forming a liquid-tight seal with an opposing flange. A radially outer annular gasket segment surrounds the radially inner annular gasket segment. The radially outer annular gasket segment is fire-rated for forming a fire-rated seal with the opposing flange.

Methods and systems are provided for a sealing device. In one example, a seal comprises a plurality of radial features and a plurality of axial features extending from a cylindrical body, the cylindrical body comprises a first material and a second material, wherein the second material is stiffer than the first material.

A gasket having concentric or spiral serrations around the aperture on each side of the gasket, and wherein a facing is secured to such serrations, wherein each facing comprises a first layer which is in contact with a respective set of such serrations and a second layer which is in contact with the first layer. The first layer could be of a polyaryletherketone or polyimide, and the second layer could be of graphite or vermiculite. The serrations are designed to avoid damage to the first layer. An intact first layer can supply a property to the facing which may be absent in the second layer; for example, good dielectric properties.

A cylinder head gasket with a carrier layer and at least one inserted sealing element, wherein the inserted sealing element has a passage opening for combustion gas, the inserted sealing element is fastened on the carrier layer on an outer side which is spaced apart from the passage opening, and the inserted sealing element has at least a first layer and at least one further layer. An engine component comprising the cylinder head gasket is disclosed, the engine component having an engine block unit, a cylinder sleeve unit which delimits the engine block unit at least in regions from a combustion chamber, and a cylinder head unit, wherein the cylinder head gasket is arranged between the cylinder head unit on one hand and the engine block unit and the cylinder sleeve unit on the other hand.

Systems for reducing leakage at a pressure barrier in a gas meter, are provided including first and second gaskets; a flexible circuit having variable thicknesses, such that a thicker portion of the flexible circuit is provided between the first and second gaskets; and a mounting plate on the flexible circuit, the mounting plate compressing the flexible circuit between the first and second gaskets on a non-pressurized side of the pressure barrier of the gas meter. Related flexible circuits and gas meters are also provided.

A sealing strip for sealing adjacent filter plate assemblies of a horizontal filter press. The disclosure is based on the idea of providing the sealing strip with a stiffener at a base portion of the sealing strip, positioned such that it intersects with a line running through a ridge provided on a distal portion of the sealing strip and extending along a vertical direction, perpendicular to both the length direction and the width direction of the sealing strip, as seen along the cross-sectional profile of the sealing strip. A filter frame, a filter frame assembly and a filter apparatus having such a sealing strip are also provided.

There is proposed an annular seal for a pipe coupling, comprising, a lower portion beatable within an upwardly open annular groove in the pipe coupling, an upper portion having an upwardly facing abutment surface, a depending skirt and a stiffening ring. The depending skirt is configured for engagement over a circular upstand of the pipe coupling, which is located inwardly of the annular groove. The stiffening ring is located within the upper portion of the annular seal, and includes an annular portion that is generally parallel with and spaced apart from the abutment surface and at least one circumferential leg depending from the annular portion that provides reinforcement for the depending leg.
