A flexible duct having a hollow tube shape. The flexible duct includes at least one end, and an opening defined by a first edge of the at least one end and forming a duct inlet or duct outlet. The at least one end includes at least a first attachment and a second attachment, and the first attachment and the second attachment are different. The first attachment and the second attachment can be used independently of one another to connect the at least one end to a first inlet or a first outlet. In one embodiment, a flexible duct includes an attachment that is a cuff. In another embodiment, a connector includes two different attachments and the connector can be affixed to a flexible duct end. In another embodiment, a method includes providing a flexible duct with different attachments at one end of the flexible duct, and flowing air through the flexible duct. In a further embodiment, a method includes providing a connector having two different attachments.

A joint is devised for connection to an internal tube of a longitudinally extensible hose. The joint includes a sleeve and a tubular insert. The sleeve includes an axial channel for receiving the internal tube. The axial channel includes a diameter-wise smaller section and a diameter-wise larger section. The tubular insert is inserted in the internal tube so that the tubular insert and the sleeve clamp the internal tube. The tubular insert includes an axial passageway, an annular bulge and an annular flange. The axial passageway extends coaxially with the axial channel. The annular bulge is formed on a middle section of the tubular insert and adapted for pressing the internal tube against an wall of the diameter-wise larger section of the axial channel. The annular flange is formed at an end of the tubular insert and adapted for contact with an end of the sleeve.

An apparatus comprising a sleeve. The sleeve has an outer surface and a flange extending from the outer surface. The flange has a first surface for engaging an edge of first flexible hose and a second surface for engaging a union. The first surface of the flange has a radial length substantially equal to a thickness of the edge of the first flexible hose. The sleeve counteracts a deflection of the first flexible hose and the second flexible hose into a flow path created through the first flexible hose and the second flexible hose when the first flexible hose and the second flexible hose are coupled together using the union, the sleeve, and a pair of fittings.

An extensible hose, comprising an inner tubular element (2) suitable, in use, for being passed through by a fluid, said inner tubular element (2) being made from a first elastically extensible material and suitable for lengthening and widening under the action of the pressure of the fluid. The hose (1) also comprises at least one extensible outer tubular element (3) overlying, and coaxial to, said inner tubular element (2), comprising at least one surface portion (4) made from a second material resistant to external stresses, and the like.

A garden hose with an outer flexible sheath of spirally wound and linked turns of sheet material, an inner tube of flexible polymer inside the sheath and end couplers with nipples press fit into ends of the tube and connector mechanisms connecting the couplers to the outer sheath. Each connector mechanism has inner and outer press fit shells at the end of the sheath, with flared ends separated by a washer.

According to the invention it is provided that a hose connecting device for connecting an elastic flexible hose to a rigid connection includes at least one coupling element having first positively locking means for coupling to the connection portion in positively locking relationship, and an annular support body which peripherally supports the coupling element, wherein the positively locking means extend radially internally on the annular support body and wherein the annular support body is adapted for fixing to the flexible hose.

A hose fitting and a method of manufacturing includes a main fitting body and an outer sleeve that surrounds the main fitting body. An axially extending nipple is formed on the main fitting body and a crimped region is defined by the main fitting body and the outer sleeve being crimped toward each other. A tube member is radially interposed between the main fitting body and the outer sleeve, and a low temperature sealing region is defined by the tube member being compressed over a grooved portion of the nipple. An elastomeric seal member is radially interposed between the main fitting body and the tube member, and a high temperature sealing region is defined by the tube member being compressed over the seal member. The crimped region, the low temperature sealing region, and the high temperature sealing region are sequentially arranged in an axial direction.

A hydraulic tube connector for vehicle may include a connector body including a through hole into which a tube having a tube protrusion protruding outward is inserted, and a pair of guide grooves formed around the through hole and a coupling member configured to couple the tube with the through hole of the connector body, wherein the coupling member includes a tube coupling portion configured to surround the tube and a pair of coupling guides configured to be inserted into the pair of guide grooves.

A quick connect coupling assembly for interconnecting a tubular component to a mounting component is provided. The coupling assembly includes a retainer adapted to be coupled to the mounting component and having a pair of resiliently cantilevered snap arms. A housing for coupling with the mounting component has an inner cam surface and is configured to abut the mounting component. The snap arms each include a first deflector ramp that is aligned in proximity to the inner cam surface and a second deflector ramp adapted to releaseably engage a back surface of the mounting component. A push/pull feature permits the retainer to be pushed and causes the first deflector ramps to engage the inner cam surface and cause the snap arms to deflect inwardly and release the second deflector ramp from engagement with the back surface and allow the coupling assembly to be pulled out of the mounting component.
