A swage visual indicator for a fluid coupling is disclosed and related methods. The swage visual indicator is achieved by a non-destructive visual indication of a swaging process by one or more swage apertures formed through a flange filled with an indicator material. The swage apertures communicate with swaging grooves of the fluid conveying components being joined. As the swaging process is conducted, the swaging grooves are filled with material from one of the fluid conveying components, and the indicator material within the aperture(s) is therefore displaced in a direction toward the exposed exterior surface of the flange. According to a successful swaging process, the indicator material is displaced to a degree such that the indicator material is visible by the unaided eye of an inspector.

Provided are connector assemblies for connecting pipes. For example, a connector assembly can include a connector formed with a hollow into which a pipe is inserted. A large diameter portion on at least one side of both end portions of the hollow where the large diameter portion is formed has a relatively large inner diameter and a housing space inside. The connector assembly also includes a ring-shaped sealing member provided in the hosing space and a grip member provided adjacent to the sealing member in the housing space. Further, the grip member has a body portion formed to contact an inner circumferential surface of the large diameter portion and a pair of sharp portions formed to be bent from both sides of the body portion and to partially bite into the outer circumferential surface of the pipe by crimping the outer circumferential surface of the large diameter portion.

A fitting (3, 3′) for connecting to a tubular element (5, 5′) having a first end section (9, 9′) comprising at least one first connection element (21, 21′), wherein the diameter of at least a part of the first connection element (21, 21′) can be reduced in a radial direction in order to produce a connection, wherein the first connection element (21, 21′) comprises at least one first hook element (21, 21′) and/or at least one first crimp (237, 437) configured to be connected in force-fit and/or form-fit manner to at least one second crimp (7, 7′) and/or at least one second hook element (235) formed on the outer surface of the tubular element, when the diameter of at least a part of the first connection element (21, 21′) is reduced, as well as a tubing connection and a method for connecting a fitting to a tubular element.

The invention relates to a coupling which includes at least: a tubular coupling member suitable for receiving a pipe and comprising one or more annular ribs, and a crimping ring arranged on the coupling member and translatably movable between a position for inserting the pipe into the coupling member, and a crimping position, in which the crimping ring immobilizes the pipe relative to the coupling member after the deformation of the one or more ribs. Recesses are formed between the coupling member and the pipe in the crimping position. The coupling has at least one exhaust opening arranged such as to provide fluid communication between said at least one recess and the outside of the coupling.

Roll grooved pipe fittings useful in the assembly of a variety of mechanically joined piping systems. These pipe fittings are roll grooved so that they can be mechanically joined directly with other like pipe fittings and/or with roll grooved straight pipe thereby substantially simplifying assembly. In addition, hybrid pipe fittings and systems are also disclosed. Methods and apparatus for manufacturing these aforementioned roll grooved pipe fittings are also disclosed and address both the roll grooving process itself, as well as various methodology and apparatus for correcting deformations that can occur as a result of the roll grooving process. Methods for using the aforementioned apparatus are also disclosed.

A central body for a hydraulic system for fluid, including a frame having a first tubular end for connecting an upstream hydraulic circuit including a first fitting, and a second tubular end for connecting a downstream hydraulic circuit including a second fitting, the central body including a passage passing through the frame in order to convey the fluid coming from the upstream hydraulic circuit to the downstream hydraulic circuit, the frame being produced from an electrically insulating material, the central body including a printed circuit having controlled electrical properties in order to conduct a part of the electrical charges flowing in the upstream hydraulic circuit and the downstream hydraulic circuit.

A crimp connection fitting includes a socket with at least one annular recess axially spaced from an annular O-ring receiving groove. The recess includes a plurality of axially spaced crimping elements such that, when the socket is crimped, it grips a conduit positioned within the socket. The crimping elements preferably are split ring spring clips. In some embodiments, multiple spaced recesses support one or more crimping elements.

A preassembly for a conduit fitting includes an annular fitting component and a conduit gripping device. The annular fitting component has an interior wall extending along a central axis from an inboard end to an outboard end. The interior wall includes an inboard surface having a first diameter, an outboard surface having a second diameter smaller than the first diameter, and an intermediate surface recessed from the inboard surface by an outward facing inboard radial wall and recessed from the outboard surface by an inward facing outboard radial wall. The conduit gripping device is retained within the annular fitting component and includes a projection extending radially outward of an outer circumferential surface of the conduit gripping device, and axially toward an inboard end of the conduit gripping device, with an end portion of the projection being axially captured between the inboard radial wall and the outboard radial wall.

An orifice holder assembly provides a boss connected by at least one arm to a base having an outlet therethrough. The boss is provided below the outlet. A tube is inserted through the boss until a bead contacts a first boss surface and the tube end is then deflected to form a lip where the lip and the bead connects the tube to the boss. An orifice body is then inserted in the tube end.
