ABSTRACT:
Live swivel coupling device has a hollow first housing and a hollow second housing, each of which is open on opposing ends in a main axial direction. The first has a generally radially symmetrical inner surface, an indentation in the inner surface, and an internal, gasket-holding extension; the second has a generally radially symmetrical outer surface to relate with the inner surface of the first housing and an indentation in the outer surface. The indentations are for retaining the rotatable bearing set when the first and second housings are coupled. At least one rotatable bearing makes up a rotatable bearing set which also serves as a retaining device to hold the housings together in the main axial direction when the housings are coupled. The device, which can be adapted to receive a male conduit or hose terminus member that can be secured with a set of cam-locking handles, also may have one or more of the following:
