A tube coupling for coupling a first tube and a second tube. The tube coupling includes an inner shroud including a ball portion and an outer shroud including a socket portion. The socket portion receives the ball portion. The tube coupling includes a compressive ring configured to elastically compress the outer shroud onto the inner shroud. The ball portion and the socket portion form a ball and socket joint. The ball and socket joint allows relative angular movement and relative axial movement between the inner shroud and the outer shroud.

The pipe ball joint includes a casing having a socket portion with a substantially spherical interior surface and a first pipe segment extending from the socket portion. The socket portion has an annular groove disposed adjacent the partially spherical interior surface. A ball pipe section includes a ball segment received in the socket portion of the casing and a second pipe segment extending from the ball segment. A seal assembly is received in the annular groove of the casing and is disposed against the ball segment of the ball pipe section. The seal assembly includes a plurality of nested seal rings that each include a concave face and a convex face.

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 double ball pipe coupling with two axes for connecting fluid pipes or conduits at eccentric angles while reducing or eliminating frictions loss. The coupling also provides movement of pipes or fluid pathways that are under low to high pressures. Two outer shell halves contain two ball joints with protruding connections and or outer fittings for most applications. The shell halves being mostly uniform or oblong or distorted for highly non-collinear connections. The ball joints containing pathways rotate within each shell half while permitting fluid flow as intended while greatly reducing restrictions.

A bathtub drain connection system includes a first drain pipe configured to couple to a drain opening of a bathtub and a second drain pipe configured to mount to a floor structure. A drain connector is extends between the first drain pipe and the second drain pipe so that the first drain pipe and the second drain pipe are coupled in fluid communication. The drain connector is configured to allow the first drain pipe to be disposed offset relative to the second drain pipe and in a direction that is substantially parallel to a plane defined by the floor structure.

A swivel knuckle assembly for interconnecting a motor and a supply line. The knuckle assembly may include a bearing member to reduce a coefficient of friction. A locking mechanism is disclosed to connect members of the knuckle assembly.
