A structure allowing a gasket to be mounted on a fluid device is provided. The gasket includes a ring with a first annular slope at a first axial end. The fluid device includes an inner sleeve with a second annular slope and an outer sleeve radially outside the inner sleeve. An outer periphery of the ring includes an annular contact face that contacts the outer sleeve and an annular non-contact face radially separated from the outer sleeve. The first annular slope contacts an outer periphery of the second slope.

The present invention discloses a quick-insertion coupling joint, where a socket is arranged in one end of a female coupler body, a seal retainer is arranged in an inner wall of the socket, a sealing gasket is arranged at the seal retainer, multiple limiting holes are arranged in a side wall of the socket, a limiting element is arranged in each limiting hole, a first boss is arranged on an outer side wall of the female coupler body, the sliding sleeve sleeves the exterior of the first boss, a coupling groove is arranged in the outer side wall of the female coupler body, a retaining ring is arranged in the coupling groove, a second boss is arranged on an inner wall of the sliding sleeve, elastic elements sleeve the exterior of the female coupler body and are arranged between the second boss and the first boss

Supported face seal assemblies and related methods are disclosed. The supported face seal assemblies have spring energized seal element supported by a backing ring. When the two components are joined, they form an interlocking face seal assembly that is less prone to separate during installation and/or service. The methods disclosed include the steps of forming a spring energized sealing element with a convex outer surface, forming a backup or support ring with a concave inner surface, assembling the sealing element into the inner bore of the backup or support ring such that the concave inner surface accepts a portion of the convex outer surface and the sealing element is retained within the backup or support ring.

The present disclosure relates to a seal for a coupling member of a type used in a fluid coupling including mating first and second coupling members. Each coupling member includes a seal cavity with a generally square shaped cross-section including an upper face, a circumferential face and a lower face. The seal includes an upper portion and a lower portion. The lower portion of the seal includes a first part and a second part. The first part of the lower portion of the seal includes an external ledge that extends away from the upper portion of the seal and which is configured during use of the coupling member to contact against the upper face of the seal cavity.

The first annular slope contacts an outer periphery of the second slope.

A seal assembly can include a sealing component and a spring energizer located within a seal cavity or spring cavity of the sealing component. The sealing component provides an exterior surface for providing protection of the seal cavity and spring energizer from an external or contaminated environment, such as the atmosphere. The sealing component can have two distinct first and second sealing points. Each distinct first sealing point can have two discrete first sealing points and each second sealing point can have two discrete second sealing points. Part of the spring energizer can extend externally of the sealing component.

A gasket capable of sealing against multiple sealing surfaces, comprising an inner seal ring for sealing against inner sealing surfaces, an outer seal ring for sealing against outer sealing surfaces, one or more intermediate seal rings for sealing against one or more intermediate sealing surfaces, and a connector member for connecting the inner seal ring, one or more intermediate seal rings and the outer seal ring. In some embodiments, the gasket includes a retaining feature for securing the gasket in place and a removal feature for removing the gasket. In some embodiments, the various components of the gasket (e.g., seal rings, connector members, retaining feature, etc.) are composed of different materials (e.g., metal, metal alloy, plastic, rubber, ceramic and/or glass).
