The invention relates to a device for a sealed connection between two doors (2, 5) which are each provided with a coaxial complementary flange (3, 7), one of the doors (5) and the flange (3) of the other door (2) being provided with at least one peripheral seal (1, 4), wherein each of the peripheral seals (1, 4) comprises an annular seal body extended in the outer peripheral portion thereof by an annular bead (11, 41), and wherein the door and the flange having the seals comprise a tubular bearing surface (34, 54) that is complementary to the outer peripheral face (11, 44) of the seal body on the one hand and a circular groove for engagement with the bead on the other hand.

A method of installing an insert in a body is provided, including advancing an insert into a bore of the body bounded by a lip so that a round seal of the insert passes the lip with a clearance therebetween, and so the insert first engages the body with a contact rim rather than the round seal. Accordingly, the round seal is not compromised to self-center the insert in the bore. The bore can include a shoulder distal from the lip. The round seal, which optionally can be an O-ring, can sealingly engage the shoulder and a secondary bore after the insert is self-centered in the bore. The round seal can be advanced farther into the body so another contact rim engages the shoulder. The insert can be heated so components of the body melt and fuse to parts of the insert during installation. A related system is provided.

A sealing apparatus includes a swellable metal. The swellable metal, when exposed to a fluid, is transitionable from an initial configuration having an initial volume to an expanded configuration having an increased volume. The swellable metal, upon transitioning to the expanded configuration in an annulus of a fluid channel, forms a seal against a surface of the fluid channel such that fluid communication across the swellable metal in the annulus is at least partially restricted.

An EGR valve device equipped with: a housing which contains a flow passage; a valve element for opening and closing the flow passage; a valve shaft to which the valve element is provided; and a mating member which includes an assembly hole in which the housing is assembled, and also includes another flow passage. The flow passage is connected to the other flow passage while the housing is assembled in the assembly hole of the mating member, and a sealing member is provided in at least one location between the outer surface of the housing and the inner surface of the assembly hole. The sealing member includes a vibration-reducing part which has a vibration-reducing function and is formed from an elastic material, and also includes a sealing part which has a sealing function.

Embodiments of the present invention provide a pre-combustion chamber assembly, comprising (a) a body, having a cylindrical end portion having a step-wise increase in diameter forming a sealing surface for sealing to an engine; (b) a tip, with a hollow shaft in fluid communication with a combustion region of the tip, where the shaft has a first shaft diameter that allows the shaft to be slid over a portion of the body; (c) a gasket mounted about the body and resting against the sealing surface, wherein the gasket comprises a wire wound washer.

A piping (1) for guiding a fluid within a drive train unit (G) of a motor vehicle includes a pipe (R). A stop (R1A) is formed at a first end (R1) of the piping (1). A sealing element (R2D) is provided at a second end (R2) of the piping (1). The sealing element (R2D) acts as an axial seal. In order to improve a sealing effect of the sealing element (R2D), the piping (1) is loaded along an extension direction of the piping (1). A drive train unit (G) for a motor vehicle including such a piping (1) and a method for installing such a piping (1) into such a drive train unit (G) is also provided.

One or more seal retention clips can be used to retain a perimeter seal within a perimeter groove defined by a fiber optic enclosure housing. Certain types of seal retention clips can include portions that embed or bite into the housing of the enclosure, and/or embed or bite into the perimeter seal. In certain examples, the seal retention clip includes tabs or teeth that assist in engaging the housing and the perimeter seal. In certain examples, the seal retention clip defines a channel for receiving the perimeter seal.

Tool fitting device for a power tool, in particular a chipping hammer, including—a holding device for receiving and holding a tool shank, a retention element extending at least around a section or sections of the holding device, and a dust protection device for preventing the penetration of dust into the tool fitting device. The dust protection device includes at least one first dust stripping element, at least one fixing bead, and at least one sealing lip element, wherein the sealing lip element is positioned in front of the retention element in the axial direction. Dust protection device for use in a tool fitting device.

A collar for use on a water filtration tank adapter. The collar is formed as a ring adapted to thread onto the tank connection end of the adapter and abut the nut portion between the tank connection end and the pipe end of adapter. An o-ring, square in cross-section, is disposed on a top surface of the collar, offset medially towards the center. This top o-ring is adapted to abut the nut portion of the adapter. Another o-ring, square in cross-section, is disposed on the bottom surface, offset medially away from the center. This bottom o-ring is adapted to abut the tank head upon use. Accordingly, a water-tight seal is formed at the tank connection end and tank head, the collar functioning as both a positive stop and as a substitute for pipe tape.

A sealing arrangement includes: a first machine element and a second machine element, each made of an electrically-conductive material; and a seal. The first and second machine elements are sealed against one another by the seal. At least one of the machine elements is made of an electrically-conductive plastic which is at least partially covered by an electrically-insulating, injection-molded skin as a result of production. The seal has an electrically-conductive support body. The support body has at least one substantially mandrel-shaped projection comprising an electrically-conductive material which is arranged on a side of the support body facing the injection-molded skin and completely penetrates the injection-molded skin.
