  • Patent number: 7963570
    Abstract: A quick to connect and quick to disconnect fluid coupling includes a clip, a male stem having an annular clip groove adapted to receive the clip, a female port having a step groove adapted to receive the clip upon insertion of the stem into the port, and a sleeve slideably disposed about the stem adapted to abut the clip and minimize shuttling of the stem within the port. The sleeve may be biased toward the clip by a dust seal abutting a shoulder of the sleeve distal from a lead-in end of the sleeve abutting the clip. Also, the sleeve may radially retain the clip, compressed in an annular groove of the stem, and/or the sleeve abutting the clip may stabilize the clip and axially align the clip with the stem, for insertion of the stem into the port.
