A connecting device is provided between a turbine housing of an exhaust turbocharger and an exhaust manifold housing of an internal combustion engine. The turbine housing and the exhaust manifold housing are kept in position via a band clamp which acts with first and second limbs, which are oriented in a V shaped manner in cross section and are connected via a web, on supporting devices, which are attached to outer circumferences of the turbine housing and of the exhaust manifold housing, and are configured in the manner of first and second ring flanges placed on each other, such that, firstly, first and second clamping surfaces of the limbs are operatively connected to third and fourth clamping surfaces of the supporting devices on first and second connecting planes, and, secondly, first and second radial supporting surfaces are operatively connected to each other on a supporting plane of the supporting devices. An intermediate ring is effective between the second clamping surface of the second limb and an inner supporting surface of the second edge flange. The intermediate ring is clamped against the inner supporting surface of the second ring flange via the second and fourth clamping surfaces and a clamping surface portion of the intermediate ring.

An end fitting (14) of a flexible pipe (14) for conveying a fluid that includes: an end vault (42) and an outer cover (44) fixed around the end vault (42), at least a front region (36) of an internal polymeric sheath (18), at least end sections (40) of at least one tensile armor layer (24, 25) arranged around the internal polymeric sheath (18), a front sealing assembly (54) arranged around the front region (36) of the internal polymeric sheath (18). The front sealing assembly (54) includes a cannula (64) supporting at least one part of the front region (36) of the internal polymeric sheath (18) and an annular protrusion (66) arranged on an internal surface (48) of the end vault (42). The front region (36) of the internal polymeric sheath (18) is circumferentially tightened between the one protrusion (66) and the cannula (64).

A swivel coupling assembly includes a first annular member having at least one annular barb, a shoulder and at least one annular groove containing a seal. There is a first bearing surface and a second bearing surface either side of the annular groove. The first and second bearing surfaces have a width equal to or greater than a width of the annular groove. There is a second annular member having an inner surface defining a bore configured to receive the first annular member. When joined, the shoulder of the first annular member frictionally engages the bore of the second annular, thereby allowing rotation. The seal engages with and seals the bore at a location between the ends of the second member. and spaced by a distance of at least the width of the first and second bearing surfaces from the shoulder and the second opening, respectively.

A coupling device for coupling to a fluid line includes a connector, a sleeve and a fastener. The connector has an end portion configured for insertion into a tube end, and has an outer surface profile that has at least one protrusion at the end portion for engaging an inner surface of a tube when the end portion is inserted into the tube end. The sleeve is configured for positioning at least partially around the connector and the tube end. The fastener threadedly engages a threaded outer surface of the sleeve, and when the fastener is threaded onto the sleeve, the inner surface profile of the sleeve engages the tube at the end portion of the connector to substantially clamp around the tube at the connector. The coupling device includes at least one clamping element for enhancing clamping of the sleeve around the tube at the connector.

An apparatus for securing a flexible pipe (10.sub.1) to a further flexible pipe (10.sub.2) in an end-to-end configuration. The apparatus includes an elongate tubular element (30) comprising a first and second end (33, 34) and an outer surface comprising a raised central region (35). At least one vent passage (55) extends at least partially across the raised central region (35).

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.

The present device provides a composite rotary union assembly which overcomes the disadvantages of prior art rotary union assemblies. The composite rotary union assembly of the present invention provides for supplying water or gas to a rotatable reel assembly, it also provides metal inserts for high wear areas of the rotary union assembly, including the threads, for longer useful life of the assembly while providing a resin structure for supporting and placing the metal portions.
