A hose connector has a first connecting joint, a second connecting joint, and a connecting duct. The first connecting joint comprises an inner neck rim having an inner threaded aperture and a containment space connecting to the inner threaded aperture. The first connecting joint further comprises a threaded outer wall, and a bottom surface of the neck rim has a plurality of engaging grooves. The second connecting joint comprises a hollow base having a neck section connected to a lip, and the neck section is configured for insertion in the containment space of the first connecting joint. A top surface of the lip has a plurality of engaging protrusions pushing against the neck rim or engaging with the engaging groove. The connecting duct comprises an outer threaded section and an enlarged flange, and the connecting duct is mounted through the neck section and the lip.

An improved end connector for a high-pressure reinforced hose that is subjected to high frequency of pressure cycles and that provides for a low compression deformation of the reinforced hose is discussed. This unique end connector has a stem and ferrule that includes a gripper or cable lock region near a coupler, or outboard end and a substantially smooth length on an outer diameter (OD) of the stem and ferrule that extends from about the gripper region to a hose receiving, or inboard, end.

Modular end apparatus, such as modular end fitting apparatus, and methods for flexible hoses, and associated components thereof. In one implementation, a flexible hose apparatus includes a flexible hose and a hose body coupled to the flexible hose, the hose body including a threaded outer surface. The flexible hose apparatus includes a cap including an inner shoulder protruding inwardly relative to a first inner surface of the cap. The flexible hose apparatus also includes a removable end fitting disposed in engagement with the cap. The removable end fitting includes an end body that is monolithic. The end body includes a first end, a second end opposite of the first end, and a first outer shoulder adjacent the first end and disposed between the hose body and the inner shoulder of the cap.

Hose has a body and a mouthpiece connected with the body. The mouthpiece is slidably placed against the body and is mounted at the end of the hose and includes a thickening. The ending has a circumferential stop placed in the axis of the mouthpiece. The stop has on its circumference a touch surface which is oriented inside, against the thickening on the mouthpiece. The mouthpiece is sealed by sealing ring against the body. The ring is placed in the sealing zone, or the mouthpiece is connected with the body by a flexible bellow. During the movement of the mouthpiece outside the touch surface and the outer surface of the hose in the zone with the thickening draw closer and the hose is held on the mouthpiece by the under pressure between the surface of the stop and the thickening.

An alignment tool and method for mounting a flexible tube between a first pipe end and a second pipe end, where the alignment tool is adapted to be used to align the first pipe end to the second pipe end, where the alignment tool is provided with a semi-circular body having a diameter corresponding to the diameter of the flexible tube, where the length of the alignment tool corresponds to the length of the flexible tube, and that the alignment tool is adapted to bear on the flexible tube during the mounting of the flexible tube between the first pipe end and a second pipe end.

A fuel connector of a fuel system is adapted to flow fuel, and includes male and female components. The male component includes a plurality of barbs each projecting radially outward, spaced axially from one-another and being circumferentially continuous. The female component includes a plurality of reinforcement rings being in a predefined axial relationship to the respective plurality of barbs when connected.

Technologies are described for devices and methods to couple a hose to another hose or apparatus. The device may comprise a first side with at least two barbed fittings, each configured to insert into a flexible hose to create a waterproof seal. A diameter of each barbed fitting may increase in size from a first end of the first side to a second end of the first side. The device may comprise a second side with at least two male fittings, each configured to threadly interact with threads of a female fitting to create a waterproof seal. A diameter of each two male fitting may increase in size from a first end of the second side to a second end of the second side. The device may comprise a separator rim attached to the second end of the first side and to the second end of the second side.

A tire comprising a tread, this tread comprising at least one channel and at least one wear indicator that is disposed on the bottom of the channel. The wear indicator has a contact face which is intended to come into contact with a road surface when the tire reaches a wear limit. The contact face has a texture that contrasts with the bottom of the channel.
