Abstract:
A quick connector for forming a joint in a fluid line consists of a female connector body having a bore which receives a male member. A sleeve surrounds and is secured on the male member in close fitting relation with the male member and with the female connector body. A retainer extends between the sleeve and a radial face formed in the connector body to secure the male member in the connector body. A secondary retainer provides enhanced retention capability. An optional plug may be positioned in the bore entrance to prevent introduction of external contaminants.

Abstract:
This disclosure relates to a releasable quick-connect fitting, comprising an insert having an annular lock groove and an annular release groove in the outer periphery thereof, the release groove having a smaller diameter than the lock groove. A receptacle has a bore for receiving the insert and an annular bore groove is formed in the bore. An annular retainer is mounted in one of the lock and release grooves and movable to the other of the grooves. The insert is movable to a lock position in the receptacle wherein the lock and bore grooves are substantially in radial alignment and the retainer extends into said lock and bore grooves, and movable to a release position in the receptacle wherein the release and bore grooves are substantially in radial alignment and the retainer extends into the release groove. A stop is removably connected to one of the insert and receptacle and engageable with the other, the stop preventing movement of the insert to the release position but enabling movement to the release position when removed.
Abstract:
A combination device for connecting together the adjacent ends of two pipes prior to passing the pipes through a pipe cleaning and/or coating process. At the completion of the coating process, the device is cut substantially in half to form a pair of removable protective pipe caps which are mounted on the ends of the newly coated pipe.
Abstract:
An aseptic coupling arrangement (50) including a first coupling device (100a) and a second aseptic coupling device (100b) is disclosed. The first and second coupling devices are substantially similar, each having a main body (102) defining a front face and a fluid passageway (108) therethrough. A first connecting feature disposed on the main body of each coupling device (100a, 100b) 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 (102) and a membrane (400) 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 (300) that is removably attached to the main body (102) and connected to the membrane (400). The removal of the protective covers (300) away from two coupled main bodies (102), in a direction parallel to the front faces, causes removal of the membranes (400).
Abstract:
A coupling for attachment to a conduit having an insertion end is disclosed. An outer surface of the insertion end of the conduit may be smooth and free of grooves, flanges and beads. A first member defines a first passageway. A second member defines a second passageway. The first member may be in spin weld engagement with the second member. A gripping ring having an inner edge defining a series of teeth may be disposed within the second member. A support ring and O-ring may also be disposed within the second member.
Abstract:
A fitting (1) comprising an external body (10) and a caliper element, lodged in an axial cavity of said body and able to block the end of a tube inside the cavity. The caliper element can be moved from a rearward position in which the tube is blocked, to a forward position in which the tube is released, and comprises a flanged rim (30) which protrudes from an end of the body. The fitting also comprises a security ring (42) joined to the end of the body from which the flanged rim protrudes and which comprises an outer portion that extends axially from the end and which can resist at least an axial force exerted manually, and an innermost portion, axially distanced from and aligned with the flanged rim of the caliper element. The innermost portion is flexibly yielding so that when subjected to an axial force exerted manually, it can be moved axially so as to touch the flanged rim. The inner and outer portions are reciprocally positioned so as to make it possible to exert pressure on the innermost portion only by means of a special tool.
Abstract:
The present invention relates to a tube coupling system (1) comprising a coupling body (3) for receiving a tube (5), a leakage sealing means (7) between the outer surface of the tube (5) and the inner surface of the coupling body (3), a gripping means (9) for gripping the outer surface of the tube (5) received in the coupling body (3), and a tube support body (19) onto which the tube (5) fits, characterised in that said tube support body (19) comprises a feedback element (20) that provides an audible feedback signal when the tube (5) is sufficiently inserted onto the tube support body (19).
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.
