Embodiments of the present disclosure provide systems and methods for an air valve and an air valve adapter. The air valve may comprise a base, a top attached to the base via a hinge, a tab connected to the top, and a gripping shape disposed at an end of the tab, wherein the gripping shape is disposed within a well of the base. The base may be attached to an inflatable apparatus via a weld or an adhesive. The air valve adapter may comprise an inserting end, a hollow end, a gripping section between the inserting end and the hollow end, and an aperture in the gripping section, wherein air may supplied in the inserting end to travel to the hollow end.

An aseptic coupling assembly, includes a first connector and a second connector. The first connector includes a first housing, a first valve member, and a first spring that biases the first valve member towards the second end of the first housing to a first closed position. The second connector includes a second housing, a second valve member, and a second spring that biases the second valve member towards the second end of the second housing to a second closed position. The first valve member is slidable away from the first closed position within the first housing to compress the first spring and the second valve member is slidable away from the second closed position within the second housing to compress the second spring. The coupling assembly further includes a seal that prevents fluid from contacting the first spring and the second spring.

A connector system including a plurality of connectors having substantially identical structure each defining a pair of fluid conduits wherein a first one of the pair of fluid conduits terminating in a male fitting and a second one of said pair fluid conduits terminating in a female fitting wherein the male fitting and the female fitting of a pair of connectors mate in a fluid transmission connection.

A male connector end having a first cylindrical portion having a first diameter, a second cylindrical portion having a second diameter, the second diameter being smaller than the first diameter, and a male transition profile between the first cylindrical portion and the second cylindrical portion. The male transition profile is sized to accommodate both a first female transition profile and a second female transition profile to fluidly couple the male connector end to either one of a first female end having the first female transition profile or a second female end having the second female transition profile.

In a hydraulic connector for connecting a portion of the hydraulic connector to a mandrel and having a seal ring with an external groove to seal between the hydraulic connector and the mandrel the method of providing a locking segments having an inner position and a radially outward second position, providing when the latches are in a first latch position a portion is engaged with the locking segments in the radially inward position and a second latch portion is disengaged from the external groove of the seal ring to release the seal ring, and providing when the one or more latches are in a second latch position the first latch portion is engaged with one or more of the locking segments in the radially outward position the second latch portion is engaged with the external groove of the seal ring to retain the seal ring.

In the case of a hose connector assembly (1) it is provided for a retaining plate (15) to be used for axially fixing at least two hoses (6, 7, 8) in corresponding hose receptacles (3, 4, 5). The hoses (6, 7, 8) are insertable into respective recesses (16, 17, 18) of the retaining plate (15) by way of a lateral insertion movement (19), and the hoses (6, 7, 8) engage behind the recesses (16, 17, 18).

A tubular coupling comprising a first connector comprising a body defining a first passageway portion and a valve area, the valve area comprising a first volume adjacent to an end of the first passageway portion; and a second volume in fluid communication with the first volume; and a first valve disposed in the first volume of the valve area; and a second connector adapted to receive at least a portion of the first connector, the second connector comprising: a body defining a second passageway portion and a valve area, the valve area comprising: a first volume adjacent to an end of the second passageway portion; and a second volume in fluid communication with the first volume; and a second valve disposed in the first volume of the valve area.

A connection to releasably connect and disconnect to a pipe to a fitting provides a pipe fitting body for receiving a pipe and a retaining ring assembly located within the fitting body for retaining and releasing the pipe. The retaining ring assembly has axially extending inwardly angled resilient retaining tabs, each of which has a pipe retaining portion. When the pipe is inserted into the fitting body to an inserted position, the pipe retaining portions engage an indentation on the pipe to retain the pipe in the inserted position. Relative movement of the axially extending inwardly angled resilient retaining tabs with respect to the fitting body from the first locked position to a second unlocked position causes each axially extending inwardly angled resilient retaining tabs to disengage from the indentation on the pipe permitting removal of the pipe from the inserted position in the fitting body.
