Abstract: A fuel line connector assembly that includes a connector, collar, and insert. The connector has a first interconnector, and the collar has a second interconnector and is constructed for attachment to a conduit of a fuel line assembly. The connector, collar, and insert are connectable together such that the first interconnector of the connector and the second interconnector of the collar engage each other along a generally axial direction and secure the connector and collar together. The insert has a keeper and, upon circumferential rotation of the insert, the keeper interacts with the first and second interconnectors and holds their engagement and maintains securement between the connector and collar. A cover having one or more actuating buttons fits over the collar and insert to enable disengagement of the insert and collar so the insert can be rotated to permit disconnection of the collar from the connector.

Abstract: A coupling for securing pipe elements together in end-to-end relation has segments joined at one end by a pivot attachment and at an opposite end by an adjustable connection member. The segments surround a central space which receives the pipe elements. A gripping body is captured between the segments. The segments have angularly oriented reaction surfaces. The gripping body has angularly oriented contact surfaces which interface with the reaction surfaces. When the segments are drawn toward each other by the connection members, interaction between the reaction surfaces and the contact surfaces forces the gripping body radially inwardly. Inwardly facing arcuate surfaces on the segments and the gripping body engage and retain the pipe elements. A method of inserting pipe elements into the coupling while the segments and the gripping body are supported on a seal is also disclosed.

Abstract: A gripping device may be used to grip an inserted member. The gripping device has a body. The body defines a passage extending therethrough between opposite longitudinal ends. The body has an outer surface and an inner surface. The body includes at least three gripping elements spaced apart around the inner surface. Each of the gripping elements has a gripping surface for gripping an outer surface of the inserted member. Each of the gripping elements is movable upon application of a radial inward force to the outer surface of the body to reduce the spacing between adjacent gripping elements.

Abstract: A quick removal fitting includes a female coupling part, a male coupling part, and a retention clip. The female coupling part includes a flange. The male coupling part (which can be for example a water pipe) has an end forming a divergent opening and includes a protrusion ring mounted thereto and a movable ring movably arranged thereon. The retention clip is made of an elastic material and is selectively set to clamp, in a removable manner, the flange of the female coupling part and the movable ring together. The retention clip that is set to removably clamp the female coupling part and the male coupling part together at a connection therebetween helps simplify assembly/disassembly and replacement. The movable ring that is movably arranged on the male coupling part helps eliminate a mounting operation involving welding.

Abstract: Couplings and/or connections include a female component engaged with a male component. A first shoulder of the female component abuts a first complementary shoulder of the male component to form a first radial seal. A second shoulder of the female component abuts a second complementary shoulder of the male component to form a second radial seal. A sealing surface of the female component abuts a complementary sealing surface of the male component to form an axial seal disposed between the first and second radial seals. Plastic and/or elastic deformation of the complementary sealing surface of the male component forms an axial seal between the female component and the male component.

The retaining member includes an operated portion provided at an extending end of the extending portion and a claw portion. The female member includes a window portion with which the claw portion of the retaining member comes into engagement. The engagement is releasable by elastically deforming the operated portion of the retaining member toward the axis line of the male member. A release tool includes at least one operating portion which is configured to come into contact with the at least one operated portion of the retaining member to press the at least one operated portion toward the axis line of the male member so as to release connection between the male member and the female member.

Abstract: A liquid-tight connector includes a threaded body, a finger/gland assembly within an annular pocket within the body, and a compression nut that engages a first threaded portion of the body. The finger/gland assembly includes a plurality of fingers attached to a sealing gland in an annular, collet-type fashion. The sealing gland and the fingers may be integral with one another. The sealing gland and the fingers may be co-molded with one another. Tightening the compression nut on the threaded body causes the compression nut to engage the fingers of the finger/gland assembly and bias the fingers toward each other. Such biasing causes the fingers to move inward and compress the sealing gland so that it forms a liquid-tight seal around the entire circumference of a cable within the body of the connector.

Abstract: A connector for a length of corrugated tubing. The connector includes a fitting including a passage therethrough, a clamping surface, a seal, and a nut operably connected to the fitting. The tubing is in fluid communication with the passage through the fitting. Axial movement of the nut towards the clamping surface-urges the tubing against the seal wherein the tubing is thereby sealingly restrained to the fitting and a clamping surface is formed capable of causing an end portion of the corrugated tube to form a flare by the end portion of the corrugated tube being compressed against the clamping surface and the seal and sealed thereagainst by the action of the nut.

Abstract: An aseptic coupling arrangement includes a first coupling device and a second aseptic coupling device. In one example, the first and second coupling devices are substantially similar, each having a main body having a front face and a fluid passageway therethrough. A first connecting feature on the main body of each coupling device may be provided for aligning and coupling the aseptic devices together. Each coupling device may also include a sealing member received in the main body and a membrane removably coupled to the main body front face to cover the sealing member. The first aseptic coupling device may also include a rotatable protective cover that is removably attached to the main body and connected to the membrane. In one example, the removal of the protective covers away from two coupled main bodies, in a direction parallel to the front faces, causes removal of the membranes.
