  • Patent number: 8240719
    Abstract: An adaptor for converting to a push-to-connect tube fitting/port a standard tube fitting/port body having a threaded portion for threaded attachment of a nut/plug, comprises a coupling nut/plug having an axially inner threaded end portion for threaded attachment to the threaded portion of the fitting/port body; a tube sealing member contained within the nut/plug for sealing to a tube having a locking surface spaced from the end of the tube; and a retention device retained in the nut/plug, which nut/plug has at an axially outer end thereof a central opening through which the tube can be inserted into the coupling nut/plug, whereby the locking surface can be engaged by the retention device to prevent axial withdrawal of the tube from the coupling nut/plug once inserted; wherein sealing and retention of the tube is effected within the confines of the coupling nut/plug and separate from and without requiring modification of the standard tube fitting/port body.

  • Patent number: 7819437
    Abstract: A flange hose fitting assembly and method wherein a captive flange is attached to a flexible hose nipple after the nipple has been crimped to the flexible hose. The flange, which may be selected from different types of flanges, is slipped over the front end of the nipple that is crimped at its back end to the flexible hose, and then locked to the nipple by a suitable retaining device, such as a retaining ring, spring, screw-on or glue-on ring, press-fit ring, piston-ring, shaft seal, U-shaped halves or other split configurations arranged around a locking groove in the nipple, etc.
