A quick coupling system where a conduit can be pushed into the coupling to secure and seal the conduit with the coupling includes a gripping ring and a seal. The seal is located outboard of the gripping ring so that the gripping ring does not damage the outer surface of the conduit engaged by the seal. The coupling system also may include a wiper outboard of the seal to clean the outer surface of the conduit as the conduit is inserted into the coupling system.

A system for detecting a leak in a duct is disclosed, including a sheath covering a duct section, a fluid concentrating device and a sensor. The sheath is attached to a boundary portion of the duct section and forms an inner space between an outer surface of the duct section and the sheath. The fluid concentrating device has an opening through the sheath connecting the inner space to an external space outside the sheath. The inner space is sealed except for the opening through the sheath. The sensor is stationed outside the opening of the fluid concentrating device and is configured to detect fluid flow from the inner space through the opening at a level corresponding to a duct leak in a pre-burst condition.

A plumbing fitting couplable with a free-end portion of a pipe. The fitting has a chamber with an opening, and an end bushing with an interior opening sized to receive the pipe free-end portion. An inward seal and gripper ring within the chamber seal with and releasably grip the pipe free-end portion. An anti-intrusion outward seal is positionable within the end bushing interior opening in fluid-tight engagement with an end bushing interior wall portion and the free-end portion of the pipe when positioned within the end bushing interior opening to prevent contaminants reaching an interior portion of the chamber containing the gripper ring and inward seal.

The present invention relates to a connector for substantially aseptic connection, said connector comprising a connector member (1) having a connection end (13) and a coupling end (12), wherein the coupling end (12) comprises a coupling element (15) for engaging a similar coupling element (15) on a similar connector (100) to form a first seal (B), and a cover (2) arranged to enclose the coupling end (12) for providing an aseptic seal that separates the coupling end (12) from a surrounding, the cover (2) comprising at least two cover portions (21A, 22A), each cover portion (21A, 22A) being configured to be successively-positioned on or adjacent the coupling end (12) of the connector member (1), wherein each cover portion (21A, 22A) comprises a seal member (21, 22) for engaging a similar seal member on a similar connector thereby to form a second seal (A) when so positioned on or adjacent the coupling end (12) of the connector member (1). The invention also relates to a method for connecting and disconnecting two such connectors.

The disclosed hose hanger apparatus is manually installable on a gas supply hose to secure and retain an end of the gas supply hose when the hose is disconnected from a gas appliance. The hose hanger apparatus is configured to engage with and protect a quick disconnect female coupler installed on the end of the gas supply hose. The hose hanger apparatus is also configured to engage with and accept a male quick disconnect nipple when installed in an opposite orientation on the gas supply hose.

An adapter for a sealing boot includes: an annular body having a radially-outward exterior surface; at least one helical thread extending radially inwardly to define a threaded interior surface and defining a plurality of roots and crests, wherein the crests extend radially inwardly a distance A from the roots; and a blocking section that extends axially across the plurality of roots and crests, the blocking section extending radially inwardly at least the distance A from the roots at junctions with the crests, and extending radially inwardly a distance B from the roots in areas between the roots and crests.

A connector for forming a substantially aseptic connection is provided, said connector having a connector member a coupling end with a coupling element for engaging a similar coupling element on a similar connector to form a seal. A method for connecting and disconnecting two such connectors is also provided.

A hose connector assembly for connecting a hose to a port of a pressurized fluid system, the system including a socket and an adapter tube in fluid communication, with an end portion of the socket adapted to be connected to a port and having a receiving opening. The adapter tube has a plug-in end portion to be pushed into the receiving opening which is adapted to cooperate with the plug-in end portion to form a plug-in connection mechanism. The adapter tube has a hose connector end fitting adapted to be received in, hold and retain a hose end portion. Complementary locking surfaces of the receiving opening and plug-in end portion are engaged when the plug-in end portion is connected by the plug-in connection mechanism to the socket to lock the adapter tube with respect to the socket against rotation about the longitudinal axis of the adapter tube within the socket.

An adapter for a sealing boot includes: an annular body having a radially-outward exterior surface; at least one helical thread extending radially inwardly to define a threaded interior surface and defining a plurality of roots and crests, wherein the crests extend radially inwardly a distance A from the roots; and a blocking section that extends axially across the plurality of roots and crests, the blocking section extending radially inwardly at least the distance A from the roots at junctions with the crests, and extending radially inwardly a distance B from the roots in areas between the roots and crests.

An anti-debris device releasably engages and covers an unconnected end of a fluid-conveying quick disconnect connector to prevent debris intrusion. The device comprises a boot defining a cavity shaped to receive the connector, a connector-receiving access opening to the cavity, and a closure member such as flexible sheet slit to form resilient fingers movable between an opening-covering position preventing intrusion of foreign matter when the boot is not being used, but that flex to a connector-receiving position when an unconnected portion of a connector is biased against the closure member. The fingers assist in retaining the device on the connector. Various embodiments allow retaining the anti-debris device to a particular connector when the device is not in use, and/or for storing/protecting multiple connectors. Related methods are also disclosed and discussed.
