A nut for joining fluid conduits in a joint assembly includes a nut body having an inner body surface forming a through-bore, for supporting a first fluid conduit and a second fluid conduit. Internal threads upon the inner body surface advance in a helical path around a nut center axis between a thread origin, and a thread terminus that is located between first and second axial end faces of the nut body. At least one of the thread terminus and the thread origin is located within an increased thickness region formed by a varied radial thickness of the nut. The nut has a reduced risk of cracking in service.

A collet includes a cap, a conduit grasper, a collet bore, and a collet slot. The grasper is composed of a flexible material such that the grasper is compressible in response to an applied force. A conduit such as a column is installed in a fluidic component by passing the conduit through the collet and into a fluidic coupling device. The collet is then coupled to the fluidic coupling device so as to compress the grasper against the column, thereby securing the column in the fluidic coupling device. The conduit may then be inserted into the fluidic component, and fluidic coupling device may be coupled to the fluidic component to complete the conduit installation. The collet or at least the cap may then be removed by moving the collet or at least the cap around the column via the collet slot. The grasper may be removed via a grasper slot.

Fittings that generally include a unitary body having an outer surface and an inner lumen forming a void within said unitary body. The lumen is configured to receive threads for mating with the threads of a female sub end of a pipe or tube. The outer surface includes at least one aperture for receiving a tool that can be inserted within said aperture so as to rotate the fitting about an axis that extends through the lumen of the unitary body. The at least one apertures provide a safe and convenient way to tighten and loosen the fitting during the process of coupling pipe or tubing.

A watering nozzle including a handle configured to be grasped by a user, an inlet connector including a flange rigidly coupled to the handle, and an inlet engagement feature, a swivel coupling including a garden hose thread and a swivel shoulder adjacent a swivel opening arranged concentrically about a central axis, the swivel coupling rotatable relative to the handle about the central axis, and an insert shank including a swivel seal in sealed contact with the swivel coupling, a first shank shoulder in contact with the swivel shoulder, and a shank engagement feature in rigid engagement with the inlet engagement feature.

Couplings for joining pipe elements have segments with attachment members with faces which contact one another when the segments are properly installed on the pipe elements. Each segment has one or more shrouds and recesses positioned along the faces. The shrouds on one segment are received within respective recesses on the other segment. The shrouds block the line of sight toward the central space which the segments surround and which receives the pipe elements. Index markings on the segments show visual inspection points to confirm proper engagement between the segments and the pipe elements.

A plug for connecting capillaries includes at least one capillary tube, at least one sealing, and at least one pressure piece. The capillary tube includes a first inner diameter and an open end section. The sealing includes a second inner diameter, a first end section and a shape adapted to seal the open end section of the capillary tube when connected. The pressure piece is adapted to exert at least axial pressure and/or force to at least a part of the sealing. The pressure piece is also adapted to host the first end section of the sealing in abutment with the open end section of the capillary tube so that the capillary tube and the sealing are aligned.

A diesel exhaust fluid transfer circuit providing a fluid transfer connector for securely connecting a port fitting of a diesel exhaust fluid device to a diesel exhaust fluid hose. The fluid transfer connector comprises an attachment nut attachable to a port fitting of the diesel exhaust fluid device. The fluid transfer connector further comprises a hose adapter including a fluid conduit and an annular wiper seal coaxially aligned with the fluid conduit. With the attachment nut attached to the port fitting, the fluid conduit is slidable over the port fitting and connectable to the attachment nut, and the annular wiper seal wipes any residue on the port fitting as the fluid conduit is slid over the port fitting.

Example aspects of riser support assembly and a riser system are disclosed. The riser support assembly can comprise a riser support pipe comprising a cylindrical sidewall defining a first end, an opposing second end, and an intermediate portion extending therebetween; and a mount defining an arm and a pedestal, the arm extending from the intermediate portion of the cylindrical sidewall, the pedestal extending from the arm distal to the riser support pipe, the pedestal configured to engage a mounting surface.

A water heating device equipped with a housing, a fan and a chamber arranged in the interior of the housing, and screws. The housing has first and second side plates which oppose one another in a first direction and extend from the ends of a back plate along a second direction intersecting the first direction. An opening part is provided in the housing on the side opposite the back plate in the second direction. The fan has a discharge opening, a first flow passage extending along the first direction, and a first flange. The chamber has an intake opening, a second flow passage extending along the first direction, and a second flange. The first and the second flanges are secured by screws. In a planar view, the center axis of the screws is slanted such that a head portion is closer to the opening part than the tip-end portion.
