Abstract
A hose coupling for attaching to the end of a hydraulic hose includes a shell member positioned about the free end of the hydraulic hose. A body member includes a first end and a second end. The second end of the body member is inserted through the shell member and into the inner diameter of the hydraulic hose. An encapsulated fastener is rotatably and slidably disposed about the body member and positioned between the first end and the shell member. The first end has a flange portion having a diameter greater than the diameter of the body member and contains a groove for receiving an o-ring. The o-ring is adapted for sealing connection to a hydraulic device.
Claims15
A hose coupling for attachment to the end of a hydraulic hose, the hydraulic hose having an outer diameter and an inner diameter and used for conveyance of fluid under pressure comprising:
- a body member having a first end portion, a second end portion, an axial length, and a bore centrally located therein and extending the axial length of the body member, the bore providing a fluid communication passage there through, the first end having a flange portion having a diameter greater than the diameter of the body member, the flange portion containing a groove, the second end adapted for insertion into the inner diameter of the hydraulic hose;
- an o-ring being positioned in the groove of the flange portion of the body member, the o-ring being adapted for sealing connection to an external device,
- a shell member having an annular recess positioned there through being adapted for receipt of the outer diameter of the free end of the fluid hose, the shell member supporting the body member and having a free end remote first end of the body member;
- and
- an encapsulated fastener being rotatably and slidably positioned about the body member between the first end portion and the outer shell.
A hydraulic hose assembly comprising:
- a length of hydraulic hose having an outer diameter and an inner diameter and used for conveyance of fluid under pressure;
- a first hose coupling for attachment to the end of the hydraulic hose, the hose coupling includes;
- a body member having a first end portion, a second end portion, an axial length, and a bore centrally located therein and extending the axial length of the body member, the bore providing a fluid communication passage there through, the first end having a flange portion having a diameter greater than the diameter of the body member, the flange portion containing a groove, the second end adapted for insertion into the inner diameter of the hydraulic hose;
- an o-ring being positioned in the groove of the flange portion of the body member, the o-ring being adapted for sealing connection to an external device,
- a shell member having an annular recess positioned there through being adapted for receipt of the outer diameter of the free end of the fluid hose, the shell member supporting the body member and having a free end remote first end of the body member;
- and
- an encapsulated fastener being rotatably and slidably positioned about the body member between the first end portion and the outer shell.
