A push to connect fitting includes a body member adapted to receive a conduit end, a conduit comprising a first end that can be axially inserted into the body member and a conduit gripping device attached to an exterior surface of the conduit, and a retainer that retains the conduit in place when said conduit is fully inserted into the body member. Additional embodiments include providing a seal with the fitting that seals the exterior surface of the conduit, an optional load retaining sleeve for the conduit gripping device, and an optional gimbal. The push to connect aspect may be realized in the form of a single action unthreaded mechanical connection.

A push-to-connect coupling with integrated filtration is disclosed. In one aspect, the coupling comprises a tube support, a collet and a filter element. The coupling may include a seal. The coupling connects to a cavity, which may be a portable fitting. The cavity may be a connection on a separate device or system, such as an air tank or other devices. The filter element may be dome-shaped. The tube support is easily assembled with the cavity, for example by threading, to capture the filter element. The tube is connected to the coupling by pushing the tube over the tube support and through the collet. The collet interacts with a reduced diameter section of the cavity to apply a clamping force from the collet on the tube and secure the tube in place. The tube is easily removed from the cavity simply by pushing the collet farther into the cavity to remove the clamping force on the tube, and then pulling the tube out.

A tube coupling to receive and hold a tube includes a coupling body (10) having a throughway to receive a portion of a tube. A collet (17) in the coupling body has legs (21) with outer surfaces that engage with a tapered surface (24) in the coupling body which urges the legs inwardly to resist withdrawal of the tube. A biasing member (26) provides a biasing force without the tube inserted to urge the legs axially onto the tapered surface. The collet (17) can grip a large variety of pipe diameters. The coupling may be supplied with a number of inserts (30A-D) for sealing with the inner diameter of a pipe, the inserts having different diameters. A tool (50) for preparing the end of a pipe to receive the coupling is also contemplated.

A single action push to connect fitting for conduit such as tube or pipe. The fitting includes a first fitting component and a second fitting component that are joined or assembled together to form a fitting assembly. The fitting assembly includes a conduit seal device and a conduit retaining device. A conduit may be manually or otherwise inserted into the assembled fitting assembly with a single axial movement and be retained and sealed without need for further action or movement of the fitting components.

The inventive system and method advantageously enable superior preserved storage and selective dispensation of liquids by storing wine (or other liquids) in a pressurized environment to ensure that the stored liquid does not come into contact with air, and then by selectively dispensing a portion of the stored liquid, in accordance with a desired dispensing regime, by utilizing a controlled source of pressure force to apply a sufficient pressure to the pressurized environment to expel the desired volume of the liquid in a pressurized stream directed to a dispensing/pouring interface through a conduit or equivalent delivery system. In at least several novel embodiments thereof, the system and method of the present invention are configured for use with wine-in-bag (WinB) products.

A pipe joint device configured to interconnect two pipes to be inserted therein through openings of both opened ends thereof including a joint main body and a joint assembly disposed in the joint main body is provided. The joint main body includes a small-diameter part formed at a central part and large-diameter parts formed at both sides of the small-diameter part. Each of the large-diameter parts has a first horizontal part, a diameter-reduced part of which a diameter gradually decreases from the first horizontal part toward the opening, and a second horizontal part extending horizontally from the diameter-reduced part toward the opening. A portion of each of the second horizontal parts is configured as a curled part inclined toward an outer-diameter direction and the opening of the pipe joint device and then again inclined toward an inner-diameter direction and the opening and having a mountain-shaped section as a whole.

An apparatus (10) for coupling with a pipe (12), the apparatus (10) including a body assembly (13) having a body (14) adapted fit with the pipe (12), and at least two gripping parts (16) moveably coupled to the body (14), the at least two gripping parts (16) being adapted to be moveable between an insertion condition, in which the gripping parts (16) are resiliently depressible to allow movement of the pipe (12) in a first insertion direction, and a gripping condition in which the gripping parts (16) each engage with opposing side walls (18) of the pipe (12) to restrict movement of the pipe (12) in a second opposing direction thereby coupling the apparatus (10) and the pipe (12). Other variations of the apparatus (10) and associated methods of use are also disclosed.

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.

A connector device for connecting to at least one component has a main body, a receiver and/or transmitter device arranged on the main body for receiving and/or transmitting signals and/or data, and a shielding device. The shielding device is arranged so as to be movable relative to the base body and has a shield for electromagnetic shielding of the receiver and/or transmitter device. The shielding device further includes a latch for latching the connector device with the component to be connected in a latching position, and a lock for securing the latch in the latching position. In the latching position, the receiver and/or transmitter device is not shielded by the shield.

A coupling device for a tube (100) having an end portion provided with an outer chamfer (101), the device comprising a tubular body (1) provided internally with an annular sealing element (62) and with an attachment member (4, 40) for retaining the end portion of the tube in leaktight manner in the body. The device includes at least one retractable abutment (6) arranged so as to oppose insertion into the body of a tube end portion that is not chamfered (200) and so that the chamfer (101) of the tube end portion that is chamfered (100) forms a cam for causing the abutment (6) to retract while it is being inserted into the body (1).

A corresponding coupling method.
