Abstract: A coupling assembly for connecting two members is provided that includes a first “male” member and a second “female” member. The first member includes a release sleeve moveably mounted thereon having a rigid release portion and a flexible sealing portion. The second member is integrated into an apparatus, such as a pump, and includes a duct therethrough for receiving the first member. Upon connection of the first and second members, the flexible sealing portion sealingly engages a recessed seat portion of the second member to substantially inhibit the ingression of contaminates into the duct when the first and second members are connected.

In other embodiments, the coupling assembly provides an improved release sleeve that releases the male member from both a conventional female member and an integral female member.

Abstract: A fluid coupling includes various features. One feature is a disconnect tool that may expand a lock ring from engagement with a lock shoulder to permit the male half and female half to be separated. Another feature is to utilize geometry and structure whereby a leak would occur to indicate the condition of wear within the coupling while the coupling halves remain mechanically coupled. A further feature is to provide connection verification structure to assure that a complete connection of the male and female halves has been made. A still further feature is to provide an anti-rotational sleeve which would selectively prevent and permit relative rotation between the male half and the female half.

Abstract: The assembly of a connection that uses cooperating grooved surfaces to provide an easily disassembled and assembled connection is improved by the use of a centered lip and cooperating groove on the contact faces of the connection halves that engage the faces of complementary connection ends to prevent lateral misalignment while the pipe ends are brought together for axial alignment.

The centering device may be used with a clamping mechanism to provide single person assembly of this type of connection despite normal field misalignments. The trapping cavity formed by the faces of the connection ends particularly enhances the pressure capacity of elastomeric gasket applications.
