A pipe connector for connecting at least two pipes, wherein the pipe connector has a first receptacle with a first insertion opening for inserting a pipe and a second receptacle with a second insertion opening for inserting a pipe, wherein the pipe connector has at least one preferably circumferential stop arranged between the first and the second insertion opening on an inner side of the pipe connector, which stop determines a maximum insertion depth of a pipe into the first and/or second receptacle, the pipe connector having at least one, preferably circumferential, sealing lip arranged on the inner side of the pipe connector between the first and/or the second insertion opening and the stop, characterized in that the pipe connector comprises a flexible region of a deformable, compressible or expandable and/or elastic material arranged between the first and the second insertion opening, so that the first receptacle is translationally and/or rotationally displaceable relative to the second receptacle. The invention further relates to corresponding arrangements of a pipe connector having at least two pipes connected thereto.

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 fluid connector assembly includes a housing, an elastic member and a floating component. The housing has an opening. The elastic member is disposed in the opening of the housing. The floating component is movably supported by the elastic member and includes a fluid passage and a first guiding structure. The fluid passage is configured to be connected to a fluid device. The first guiding structure is configured to engage with a second guiding structure of the fluid device.

A system includes a conduit and a gasket assembly. The conduit includes a body and has a bell defining an opening disposed at one end of the conduit. The bell includes a ridge defining a circumferential internal groove, a sloping portion defining an internal recessed area and disposed adjacent to the ridge, and an abutment end inwardly extending from the sloping portion in a direction that is perpendicular to a central axis defined by the bell. The gasket assembly is disposed within the internal groove. The gasket assembly includes a plurality of gripping inserts each comprising a hollow body and an elastomeric gasket having a circular shape and being disposed within the hollow bodies defines by the plurality of gripping inserts.

A flexible pipe fitting for joining a first length of pipe to a second length of pipe at an arbitrary angle is provided. The apparatus includes a primary fitting having a substantially circular opening at a first end thereof for receiving an end of a first length of pipe, and an enlarged opening at a second end thereof for receiving a first flexible coupling member. The first flexible coupling member includes an outer wall having an outer surface engaging an inner surface of the enlarged opening, and an inner wall having a lower end connected to a lower end of the outer wall. The inner wall further includes a substantially circular opening therein for receiving a second, rigid member. The inner surface of the second, rigid member is configured to receive an end of the second length of pipe. The enlarged opening in the primary fitting is preferably fish-mouth shaped, or alternatively, cone shaped. Adhesive, such as PVC cement may be used to bond the various fittings, and lengths of pipe together to form a sealed joint.

A duct coupling system includes a first and second duct, a vibration attenuation system, a rigid ring, and a fastening system. The first duct has a first flange aligned with a second flange of the second duct. The vibration attenuating system abuts a first side and a second side of the first flange and abuts a first side of the second flange. A portion of the vibration attenuating system encircles the first duct. The vibration attenuating system is configured to attenuate vibrations passing between the first and second ducts. The rigid ring encircles the first duct and abuts the vibration attenuation system. The fastening system couples the first duct to the second duct and compresses the vibration attenuating system. The rigid ring does not contact the first duct and the first duct does not contact the second duct.

A fluid connector assembly includes a housing, an elastic member and a floating component. The housing has an opening. The elastic member is disposed in the opening of the housing. The floating component is movably supported by the elastic member and includes a fluid passage and a first guiding structure. The fluid passage is configured to be connected to a fluid device. The first guiding structure is configured to engage with a second guiding structure of the fluid device.

A seal for a flexible alignment sealing coupling. The seal includes an annular member being symmetric about a longitudinal axis. The annular member has a radially inward facing surface extending an axial width between a first axial end and a second axial end. In a relaxed state of the seal, the radially inward facing surface has an asymmetric generally concave V-shaped cross section and is defined by a first section and a second section. The first section has a first seal taper angle measured relative to a line parallel to the longitudinal axis. The second section has a second seal taper angle measured relative to another line parallel to the longitudinal axis. The first seal taper angle is less than the second seal taper angle. Each of the first seal taper angle and the second seal taper angle is greater than zero degrees and less than 90 degrees.

A grooved-ended resilient expansion joint is disclosed. The expansion joint has a resilient expansion member with a central resilient portion and two resilient axially disposed cylindrical ends. Each cylindrical end has a radially outwardly raised distal cylindrical gasket portion with at least one inside shoulder having an inner diameter sized substantially the same as an outer diameter of a pipe to be joined. A pair of pre-assembled pipe couplings are provided for joining the expansion joint to a pair grooved-ended pipe segments without disassembling the coupling.

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.
