Provided is a fluid transfer connector plug that allows for easy engagement of keys with key grooves. The fluid transfer connector plug includes: a plug body having a proximal end and a distal end, the proximal end allowing a hose to be fixed thereto, the distal end being removably connected to a socket, the plug body including a fluid channel communicating with the hose; a key plate on an outer periphery of the plug body, the key plate being rotatable relative to the plug body; and two or more keys on the key plate. The plug further includes a main key having a larger circumferential width than that of each of the other keys.

A device for connecting fluid lines and other lines. The device has a first connection component for connecting fluid lines and a second connection component for connecting other lines. The first connection component has a first functional position, in which the first connection component disconnects the two fluid lines from one another, and a second functional position, in which the first connection component connects two fluid lines. The second connection component, in a connection position, connects two other lines and, in a release position, disconnects the two other lines from one another.

A dry disconnect device including a first portion defining an outlet and an outlet portion of a fluid pathway and a female valve disposed within the first portion having an extended position, including the female valve being configured to seal the outlet portion, and a retracted position. A second portion defining an inlet and an inlet portion of the fluid pathway is lockingly engageable with the first portion. A male valve is disposed within the second portion including a male valve transition member configured to translate the male valve from an extended position to a retracted position including the male valve being configured to seal the inlet portion. The extended position of the male valve causes the female valve to transition from the extended position to the retracted position and causes the outlet portion and the inlet portion of the fluid pathway to be in fluid communication with each other.

Certain embodiments of the present invention provide a fill gun apparatus for interconnection of a pump truck and a pressurized liquid delivery system. The fill gun apparatus can be easily attached and detached from an inlet port to deliver a pressurized fluid, for improved delivery, increased efficiency, increased safety, and decreased waste.

A torque limited fitting is provided having a head and a body, which in certain embodiments may be assembled by an operator. The body of the torque limited fitting has a passageway therethrough for receiving and removably holding tubing. The torque limited fitting may be adapted for use with a flat bottom port, such as in an analytical instrument, like liquid chromatography, gas chromatography, ion chromatography, or in in vitro diagnostic systems.
