The invention provides an articulated joint in a pneumatic conveying system of a boom of an agricultural dry product applicator. The joint allows adjacent product-conveying tubes and respective joint components to articulate with respect to each other while maintaining a seal for pneumatically conveying product. Joint components may be separated from each other when the boom is folded while articulating with respect to each other without disengaging or creating potential leaks at segment junctures while the boom is extended. The articulated joint includes a rigid socket having a first socket section and a second socket section providing support to a compressible seal having a first seal section and a second seal section. The first seal section is inserted into the second socket section to create an airtight seal in between the first seal section and the second socket section even when boom tube segments flex during use.

A coupling member for a blind mate fluid coupling includes a housing and a valve body that is self-centering and alignable relative to the housing. The valve body may include at least two radial shoulder portions that are configured to engage at least two corresponding radial abutments of the housing to improve self-centering when in a decoupled state. An engagement member, such as a socket, may be provided in the housing to engage a radial shoulder of the valve body with a concave interface to enhance the misalignment compensating and/or self-centering functionality. The engagement member may be free to float radially relative to the housing to further enhance such effects. A compensator that urges an engagement member against a shoulder of the valve body may be provided to compensate for misalignment and/or provide self-centering in both a decoupled and mated state.

A slip-on adapter that is adapted to be coupled to existing adapters that have already been developed. The slip-on adapter couples to existing adapters by positive retention on either the outside diameter or inside diameter of the existing adapter. For example, the slip-on adapter can include an O-ring that grips the outside diameter of the existing adapter that it is slipped onto. The slip-on adapter can also be used as a “flip adapter” with different geometries at both ends for use with two different size ball joints. This allows for less expensive adapters for new size ball joints by connecting to existing adapters, rather than requiring full machining of a new adapter.

A ball joint having first and second articulated coupling parts having interconnected liquid ducts. The second coupling part is held pivotably by a spherical front end region between a shape-adapted joint socket on the first coupling part and a joint head on a holding element in the inner cavity of the second coupling part. The holding element interconnects the liquid ducts, and the second coupling part has, on its inner wall delimiting the inner cavity, an annular groove with a ring seal. A first annular shoulder is on the inner wall of the second coupling part, an annular insert part is insertable into the inner cavity of the second coupling part, and the insert part is spaced apart from the first annular shoulder such that the spacing between the first annular shoulder and the front edge of the insert part facing the first annular shoulder forms the annular groove.

A coupling device configured to couple first and second pipes, which comprises a first part coupled to the first pipe and which has a first contact surface, a second part coupled to the second pipe, separate from the first part, and which has a second contact surface configured to collaborate with the first contact surface, at least one clamp comprising at least one clamping jaw comprising a groove, configured to collaborate with the first and second parts, which has a cross section such that a concentric tightening of the clamp causes the first and second contact surfaces to be kept pressed against one another. Thus, the coupling device makes it possible to obtain a ball joint type connection between the first and second pipes.

Provided is a liquid pipe coupling universal joint capable of easily performing a pipe mount work even in a narrow space, remarkably reducing a piping work cost, providing a high coupling strength in a structure of the universal joint itself and excellent vibration and earthquake resistance.

Disclosed is a pipe coupling universal joint (100) in which an edge circumference (12, 13) of the first or second fitting portion (3, 7) is formed in a position separated from a reference plane (T) by a length (L) set to 21 to 23% of the maximum diameter length (R1, R2) of the first or second fitting portion (3, 7) on the reference plane (T) in a direction (V) opposite to a side where the straight pipe portion (1) is connected from the reference plane (T) defined herein.

A load bearing flexible conduit system for use in a body of water and adapted for deployment from a reel located on a water going vessel into the body of water is disclosed. The system comprises a number of lengths of load bearing flexible conduit, each length of load bearing flexible conduit provided with an inner layer having a throughbore and a load bearing outer layer. A joint for connecting the lengths together has a body having a longitudinal axis and a throughbore and at least one flexible coupling to permit at least one of the ends of the respective first and second lengths of load bearing flexible conduit to move relative to the longitudinal axis of the joint.
