Abstract:
A plug for a connector includes an insertion portion, and the insertion portion includes an O-ring abutment portion and a creep prevention portion. Also, when the insertion portion of the plug for a connector is inserted in a mouth portion of a connector, the O-ring abutting portion abuts against an O-ring mounted inside the connector, and closes the mouth portion of the connector. Also, the creep prevention portion prevents a creep of a lock member which is in a standby position.
Abstract:
An apparatus and method for plugging a tubular bore is disclosed herein. The apparatus comprises: a shaft member; one or more cylindrical compressible seals slideably disposed around the shaft member, wherein the shaft member passes axially through the one or more cylindrical seals; one or more cylindrical hard sleeves having one or more conical ends slideably disposed around the shaft member and adjacent to the one or more cylindrical seals; a flange attached at or near a distal end of the shaft member, wherein the flange retains the cylindrical sleeves and cylindrical seals on the shaft member; and a pulling mechanism disposed at or near a proximal end of the shaft member, wherein the seal is positioned between the flange and the one or more cylindrical hard sleeves such that compression of the seal causes it to expand away from the shaft member.
Abstract:
In an embodiment, a hose coupling assembly includes a collet including a head and an axial protrusion extending from the head in a first axial direction. The axial protrusion is configured to engage a hose while the axial protrusion is in a locked position, and to disengage the hose while the axial protrusion is in an unlocked position. The hose coupling assembly also includes a housing disposed about the axial protrusion and configured to receive the hose. An inner surface of the housing is shaped to enable movement of the axial protrusion toward the unlocked position in response to movement of the axial protrusion in the first axial direction, and to drive the axial protrusion toward the locked position in response to movement of the axial protrusion in a second axial direction, opposite the first axial direction.
Abstract:
An open ended cap for a pipe is provided comprising a flexible tubular body wherein one end has an inwardly-extending radial rim extending in a plane perpendicular to the longitudinal axis of the tubular body of the end cap. The tubular body may include a finger grip member extending inwardly from an inner periphery of the rim and connected to a tear strip extending across the rim and downwardly along at least a portion of the tubular body. In another embodiment, the tubular body has an interior wall surface having multiple compressible longitudinal fit beads extending from the interior wall surface and spaced about the circumference of the interior wall surface and which are configured to provide contact with the external surface of a pipe upon being inserted into the end cap. Both a tear strip and longitudinal fit beads may also be provided in combination.
Abstract:
This invention relates to a tube coupling system (1) for a pressurised fluid system comprising a coupling body (3) for receiving a tube (5) of a pressurised fluid system, a leakage sealing means (7) for preventing fluid supplied from the pressurised fluid system via the tube to enter the coupling body (3), a gripping means (9) for gripping the outer surface of the tube (5) received in the coupling body (3), and an environment sealing means (11) for preventing intrusion from outside of the coupling body (3), characterised in that said environment sealing means (11) is at least partially displaceable and arranged to be pressed at least partially off a sealing seat when there is internal fluid pressure in the coupling body (3) resulting in a fluid stream out of the coupling body (3) and said fluid stream to the outside of the coupling body (3) indicates a leakage from the pressurised fluid system.
Abstract:
A connecting device for a plug-in connection of at least one pipeline having a housing part having at least one receiving opening for the insertion of the pipeline. A clamping ring is arranged in the receiving opening and, in order to lock the pipeline in place, interacts with an inner cone of the housing part. The housing part is made in two parts including a base part and an insert part, which is connected to the base part via a snap-in action forming-fitting connection. The insert part has a direct seal for resting on the circumference of the inserted pipeline. The insert part is formed of a first relatively hard and dimensionally stable plastic material, and has a dirt seal which consists of a second, relatively soft and elastic plastic material and is molded directly into the first material as a single piece with a cohesive material joint therebetween.
Abstract:
A plug connector for inserting a tubular plug-in part in a fluid-tight manner, useful for plastic pipe conduits is provided, consisting of a housing part with a plug-in receptacle, a retaining element and a fluid seal arranged in the plug receptacle; the housing part having a two-piece base part consisting of a receiving part for the retaining element and a connection part for connection of the housing part, to e.g., a threaded bore.
Abstract:
A plug connector for fluid conduits. The plug connector including a housing part with a plug socket for the fluid-tight insertion of a tubular plug-in part, a holding element for locking and a fluid seal for sealing the inserted plug-in part. The plug connector being arranged in a plug socket, the housing part being in two parts comprising a base part and an insert plate which is connected to the base part via a snap-action positive fit connection. The base part comprising a receiving part for the holding element, the fluid seal and the insert part, and a joining part for the joining connection of the housing part to a fluid conduit.
Abstract:
The quick connect member (20) has a pair of arms (32) biased radially outwardly into a locked position in radial overlapping engagement with a shoulder (25) in a socket member (21) to retain a tube (26) in the socket member (21). The arms (32) extend from a disk (34) through flat and parallel axial sections (35) and then through outwardly flared sections (36), the arms (32) being arcuate in cross section between the axial sections (35) and the ends (33) thereof to terminate in arcuate ends (33). Each of the axial sections (35) includes an opening (39) extending tangentially to the tube (26) for receiving the projection (28). The socket member (21) has a pair of oppositely disposed radial holes (38) adjacent the shoulder (25) for accessing the arms (32) by inserting a tool through the holes (38) to move the arms (32) radially inwardly to a release position to clear the shoulder (25) to axially remove the quick connect member (20) from the socket member (21) to remove the tube (26) from the bore (22) of the socket member (21).
Abstract:
Embodiments of the present invention relate to methods for protecting a threaded end of a tubular member and sealingly engaging the tubular member to prevent liquid or debris contamination of the threaded end. In the preferred embodiments, the methods comprise the use of a tubular member thread protector that includes a protector body having an open end providing access to an interior and a closed end. The open end is adapted to accept the threaded end portion of the tubular member. The exterior surface of the protector body has a seal groove located proximate to the open end of the protector. A compliant seal is adapted to attach to the seal groove on the body and extend over the open end of the body and sealingly engage the outer surface of the tubular member.
