摘要： A sealing arrangement is provided for sealing a mounting groove formed in a first or second mounting member separated by a gap and defining a hydraulic passage. A gasket is mounted in the groove between the passage and gap. The gasket includes an annular gasket body having first and second axial ends and a buried reinforcement ring. The gasket body includes a unitary flange extending radially outward from the first axial end. The flange includes a first seal lip extending axially outward from the flange proximate the passage or gap. The first seal lip contacts a surface of the first or second mounting member facing the passage. The gasket body includes a second seal lip extending outward from the second axial end to contact a bottom surface of the mounting groove.

摘要： 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.

摘要： An electrically and thermally conductive gasket includes a resilient core including a plurality of sides, a heat spreader disposed along at least two sides of the plurality of sides of the resilient core, and an electrically conductive layer disposed along and/or covering at least a portion of the heat spreader, such that the portion of the heat spreader is between the resilient core and the electrically conductive layer. The gasket is positionable and/or compressible between first and second surfaces to thereby define an electrically conductive path and a thermally conductive path between the first and second surfaces.

摘要： A gasket retainer that is absent sharp corners, has apertures of reasonable dimensional tolerance, and may be conveniently made by a variety of manufacturing processes. The retainer is made from thin flat springy material that readily returns to form after slight bending. Representative gasket capturing apertures are of smoothly non-convex outline with major dimension sufficiently large to allow passage of a ring shaped gasket turned on edge and minor dimension sufficiently small to engage, on approximately opposite circular segments that each engage along less than one third of a gasket circumference, a cavity or groove on the outside diameter periphery of the gasket turned flat parallel to the retainer material sheet. Fasteners may be retained by similar apertures.

摘要： A coupling assembly having first and second sleeves configured to be tightened to a fluid conduit, a radial-split gasket configured to be positioned between the sleeves and the fluid conduit and having an outer gasket layer and a separate inner gasket layer configured to be selectively disengaged from each other, the outer gasket layer having a radial gap defined by first and second radial side wall gap surfaces, the inner gasket layer having a radial gap and a radial insert configured to be received in the radial gap of the outer gasket layer between the first and second radial side wall gap surfaces.

摘要： A gasket for a combustion chamber is provided. The gasket comprises an upper assembly including an upper combustion sealing section with a raised bead positioned between a first component and a second component adjacent to a combustion chamber and an upper fluid sealing section positioned between the first component and the second component at a location spaced away from the combustion chamber. The upper combustion sealing section includes an anti-fret coating on a metal layer, the upper fluid sealing section includes a synthetic rubber coating on a metal layer, and the upper combustion sealing section is greater in thickness than the upper fluid sealing section.

摘要： 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.

摘要： A single piece gasket is disclosed having a skeletal member, typically metallic, and a pliable body. The pliable body includes a first portion having a first firmness and a second perimeter portion have a firmer consistency. When such a composite body is placed under compression, the perimeter will tend to limit the flow of the softer inner material past the firmer perimeter region or portion of the gasket. In this manner, creep or overrun of the less firm portion material will be reduced.

摘要： Gasket seals for high pressure applications include retaining elements with inner diameter seal elements that interlock with the retaining element to provide resistance to movement in both axial and radial directions between the retaining element and seal element. High pressure sealing may be accomplished using a metallic core retaining element to which an electrically isolating material is bonded on either or both sides. Sealing is achieved through an inner diameter dielectric sealing element, such as a polytetrafluoroethylene (PTFE) inner diameter sealing ring. Flanges of a joint in a fluid flow ling may be bolted together with the gasket seal interposed therebetween. In the event of pressure changes, the inner diameter seal resists being drawn into the flow line, and resists axial movement relative to the retaining element, through dual locking members that secure the seal to the retaining element.
