Compact flexible reinforce rubber hose adapted for conveying fluids under high pressure. The hose includes a thin inner tube formed of a vulcanized rubber.

Compact high pressure rubber hose

Flexible reinforced rubber hose adapted for conveying fluids under low temperatures and high pressures. The hose includes a inner tube formed of an acrylonitrile butadiene rubber (NBR) or other low temperature rubber compound having an elastic modulus of not greater than about 8.4 MPa (1200 psi), and an outer jacket formed of a chloroprene rubber (CR) or other low temperature rubber compound having a durometer of not greater than about 75 Shore A.

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.

Adaptor and method for converting standard tube fitting/port to push-to-connect tube fitting/port

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 ().

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.
