Abstract
An apparatus for connecting an evacuation hose to a system for evacuation of the system. The apparatus includes a first connector, a second connector, and a seal. The first connector includes a first face defining a longitudinally extending indentation and the second connector includes a second face with a protrusion that is positionable within the indentation. The seal is positionable on the protrusion to circumscribe the protrusion and to be sealing engagement with the first connector and the second connector when the protrusion is at a preferred position in the indentation.
Claims19
An apparatus comprising:
- an evacuation hose that is configured to evacuate content of a refrigeration system;
- a system attachment portion that is configured for attachment to the refrigeration system;
- a first connector that is configured for attachment to the refrigeration system, the first connector including a first face, wherein the first face defines an outlet of a first fluid passageway, wherein the first face further includes a longitudinally extending indentation that circumscribes the outlet of the first fluid passageway;
- a second connector including a second face, wherein the second face defines an outlet of a second fluid passageway, wherein the second face includes a protrusion extending therefrom, wherein the protrusion comprises a first portion and a second portion, wherein the outlet of the second fluid passageway is recessed with respect to an end of the protrusion, wherein the first portion of the protrusion is positionable within the indentation of the first connector, wherein positioning the first portion of the protrusion within the indentation aligns the outlet of the first fluid passageway and the outlet of the second fluid passageway, and wherein one of the first connector or the second connector is coupled to the evacuation hose and wherein the other of the first connector or the second connector includes the system attachment portion;
- and
- a seal positionable on the second portion of the protrusion of the second connector,
- wherein the seal is positioned on the second portion of the protrusion of the second connector to circumscribe the second portion of the protrusion and to be in sealing engagement with the first connector and the second connector when the first portion of the protrusion is at a preferred position in the indentation.

A method of connecting a coupling comprising:
- positioning a seal on a protrusion of a second connector, wherein the seal is positioned to circumscribe the protrusion of the second connector, wherein the second connector comprises a second face defining an outlet of a second fluid passageway, wherein the protrusion extends from the second face such that the outlet of the second fluid passageway is recessed with respect to an end of the protrusion;
- aligning the protrusion of the second connector with a longitudinally extending indentation of a first connector, wherein the first connector includes a first face defining an outlet of a first fluid passageway, wherein the indentation is formed on the first face and circumscribes the outlet of the first fluid passageway;
- positioning the protrusion of the second connector in the longitudinally extending indentation of the first connector such that the seal is in sealing engagement with the first connector and the second connector;
- and
- coupling at least one of the first connector or the second connector to an evacuation hose, wherein the evacuation hose is configured for use in evacuating fluid from a refrigeration system, wherein the other of the first connector or the second connector includes a system attachment portion that is configured for attachment to the refrigeration system.
