In one embodiment, a male coupling connectable to and separable from a female coupling (e.g., a female threaded port) is provided.

A first magnet is built into the male coupler, and a second magnet is built into the female coupler.

The female coupler has a distal end and a proximal end.

A male coupler and a female coupler are formed on the top surface and bottom surface, respectively, of the block body.

Control line with a female coupling corresponding to ISO 5676:1983

The female coupling includes a receiving portion sized to receive at least a portion of the male coupling, where the receiving portion has internal threads provided therein.

A sanitary coupling assembly for mounting on a fluid system includes a female coupler and a male coupler.

A testing port shall be provided as close as possible to the female ISO 16028:2006 coupling.

A cylindrical standpipe (23) is attached to and extends axially from the female connector.

In the first stage connection, a plurality of detents 78 in the female coupler 12 are urged into a detent recess 150 in the male coupler 14 to coupled the female 12 and male couplers 14.

The end (24) of the standpipe remote from the female coupler comprises a ramp or cam sloping to a lug slot (25) in the standpipe that extends toward the male coupler.

A self-aligning electrical connector is provided for aligning and connecting multiple pins (11) of a male coupler (10) with corresponding multiple pin sockets (21) of a female coupler (20) in a blind environment.

Axial movement of the sleeve (52) relative to the stem valve (64) opens the female coupling member (20) to the flow of fluid.

Testing ports shall be provided as close as possible to the energy storage device with piston (or equivalent device) and to the female ISO 5676:1983 coupling.

1.1.The liquid coupler on the loading arm must be a female coupler which must mate with a 4-inch API (101,6 mm) male adapter located on the vehicle as defined by:U.K.
