The invention concerns a ring (4) for fastening a pipe (1) to a tubular body (2). According to the invention, the ring comprises two rigid sectors (5) that are coupled to each other by at least one elastically deformable annular portion (12), the two sectors and the portion being a single part, each sector (5) having an inner face (6), protruding from which at least one anchoring stud (7) extends radially, intended to be received in a housing correspondingly provided in a wall of the pipe, each anchoring stud (7) comprising two grooves (9) extending circumferentially to either side of said anchoring stud. The invention also concerns connection means comprising such a ring.

An enhanced union connection for connecting tubular members together. The enhanced union connection may include a male end member, a female end member, a wing nut, and nut retaining segments. The union connection

Provided is a flexible hose assembly having an inner nipple coupled to an inner flexible hose and an outer nipple at least partially surrounding the inner nipple and being coupled to an outer flexible hose, wherein a first fluid flowing through the inner nipple is directed outward in-between the inner and outer flexible hoses and a second fluid flowing in-between the inner and outer nipples is directed inward to the inner flexible hose. By directing the second fluid inward and the first flow outward, the outer flexible hose is prevented from collapsing on the inner flexible hose when pressure of the second fluid flowing through the inner flexible hose is greater than a pressure of the first fluid flowing through the outer flexible hose.

Aspects of the present disclosure relate to 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.

An coaxial keg connector comprising a main body (1) made of plastic and having a first inlet port (3) and a second inlet port (3) receiving a stem (2). A coaxial outlet (10) comprises an outer outlet port (11) in communication with the first inlet port (3) and an inner outlet port (12) in communication with the second inlet port. The stem (2) comprises a tubular body with a main axis (31) with an inlet and a connector for attachment to the keg at one end. The second end of the stem opposite to the first end has an outlet in fluid communication with the inner outlet port (12) and comprises a ball joint (61) rotatably mounted in and sealed with respect to the main body (1) so as to be rotatable (12) about the main axis (31) of the tubular body and rotatable (67, 68) to a limited extent about axes perpendicular to the main axis.

A joint that is coupled to a cylindrical fluid discharger whose peripheral edge expands radially outward. The joint includes a cylindrical coupler that is coupled to the fluid discharger and has a male screw on an outer peripheral surface thereof, an engager that engages with the peripheral edge, and a tubular body that has a female screw to be coupled to the male screw on an inner peripheral surface thereof, and switches between a first state in which the attachment and the detachment of the fluid discharger and the joint are allowed and a second state in which the attachment and the detachment of the fluid discharger and the joint are restricted.

A diesel exhaust fluid transfer circuit providing a fluid transfer connector for securely connecting a port fitting of a diesel exhaust fluid device to a diesel exhaust fluid hose. The fluid transfer connector comprises an attachment nut attachable to a port fitting of the diesel exhaust fluid device. The fluid transfer connector further comprises a hose adapter including a fluid conduit and an annular wiper seal coaxially aligned with the fluid conduit. With the attachment nut attached to the port fitting, the fluid conduit is slidable over the port fitting and connectable to the attachment nut, and the annular wiper seal wipes any residue on the port fitting as the fluid conduit is slid over the port fitting.

A split coupler, and methods of making and using such a split coupler, whereby the split coupler includes a first semi-cylindrical member, a second semi-cylindrical member, and an interlocking assembly configured to interlock the first and second semi-cylindrical members to form a substantially cylindrical coupler having a coupler inner surface which defines a throughbore. Additionally, the split coupler can include spiral threads coupled to the coupler inner surface. Furthermore, the split coupler can include a flange inwardly extending from the coupler inner surface.

A fitting for a fluid line that will contain pressurized fluid can include first and second fitting elements with respective sealing surfaces and an indicator element for indicating when a fluid seal has been formed. A fitting for a fluid line that will contain pressurized fluid can include first and second fitting elements with a sealing structure secured in one of the first and second fitting elements, wherein the sealing structure is axially resiliently compressible, one example of which includes a bellows element.

A brake union for providing a secure and leak free connection between first and second fluid carrying lines inserted into a female union body having a first and second open ends. Each of the fluid carrying lines exhibits an expanded, typically flared, end form which, upon inserting through the female body, seat against one another. A mating flare nut coaxially surrounds one of the fluid carrying lines and includes exterior threads which inter-engage interior threads of the female body, with tightening to establish a fluid-tight connection between the opposing end forms.
