The invention is a tapping assembly for use on a pipe or tank. It includes a hollow body that sits flush on the outer wall of the pipe or tank and includes a plurality of locking members that sit flush within the body and form a threaded portion into which a cap is insertable. Each locking member extends into the interior of the pipe or tank, and has an outwardly extending flanged portion that engages with the inner sidewall of the pipe or tank. When the cap is tightened against the body, it causes each of the locking member to retract, thereby causing the respective flange portions to lock the assembly against the pipe or tank wall. The assembly can be manufactured to provide either an orthogonal tap, or an angled tap, relative to the longitudinal axis of the pipe, or plane of the tank sidewall.

An elastomeric press-in-place swivel fitting adaptor and a swivel fitting assembly using the adaptor are disclosed herein. The swivel fitting assembly includes retention and sealing features that allow it to be installed in a threaded port by hand. It is suitable for use in a variety of low pressure fluid passage and venting applications.

A liquid dispenser filling hose for use in filling a liquid dispenser with liquid from a liquid reservoir via a pump, comprising: a distal coupler for coupling the filling hose to the liquid dispenser; and a controller arranged to control the pump. The liquid dispenser may be filled using a method comprising: providing a liquid reservoir, a pump and a controller arranged to control the pump, and a filling hose having a proximal end and a distal end, the proximal end of the filling hose being coupled to the liquid reservoir; coupling the distal end of the filling hose via a distal coupler to the liquid dispenser; and transferring liquid from the liquid reservoir via the filling hose to an airless liquid container forming part of the liquid dispenser. A system for filling a liquid dispenser, comprising: the liquid filling hose; and a liquid reservoir and/or liquid supply station is also described.

A coupling may be configured to receive and secure an insertion end of a conduit. An outer surface of the insertion end of the conduit may be smooth and free of grooves, flanges and beads. A first member of the coupling may define a first passageway. A second member of the coupling may define a second passageway. The first member may be in spin weld engagement with the second member. A gripping ring having an inner edge defining a series of teeth may be disposed within the second member. A support ring and O-ring may also be disposed within the second member.

Wall feed-through element for a fluid line that includes a housing having a feed-through region running in an axial direction with at least one attachment geometry and a stop. The feed-through region is structured with a bearing section and the connection geometry, on a side of the bearing section facing away from the stop at least one, includes at least one shaping protruding radially over the bearing section with a back wall facing the stop and at least one radially springable projection that is offset in a circumferential direction with respect to the shaping and extends toward the stop in an axial direction and beyond the back wall.

A method for manufacturing a pipe is described, wherein the method comprises a step of fastening a second mechanical quick connection member to a rectilinear hollow tubular body, a step of positioning the rectilinear hollow tubular body in a bending machine so that the angular coding mechanism of the second mechanical quick connection member is in a reference angular position with respect to said bending machine, and a step of bending the rectilinear hollow tubular body as a function of said angular reference position.

A plumbing fitting assembly includes an anchor member for being received in a transverse hole in a structure. One end of the anchor member is externally threaded and the other includes a catch portion for engaging a surface of the structure adjacent the hole. The threaded end is threaded into a clamping member configured to form a seal with the opposite surface of the structure or another liquid conveying structure. The anchor member can include a tool formation for mating with a rotating structure of a tool. The assembly can include a lock ring for being lockingly received in an interior passage to prevent the catch portion from deflecting inwardly when installed. The plumbing fitting assembly can also be configured for forming a plumbing fitting at a transverse hole in a flexible, liquid-impermeable panel.

A liquid dispenser filling hose for use in filling a liquid dispenser with liquid from a liquid reservoir via a pump, comprising: a distal coupler for coupling the filling hose to the liquid dispenser; and a controller arranged to control the pump. The liquid dispenser may be filled using a method comprising: providing a liquid reservoir, a pump and a controller arranged to control the pump, and a filling hose having a proximal end and a distal end, the proximal end of the filling hose being coupled to the liquid reservoir; coupling the distal end of the filling hose via a distal coupler to the liquid dispenser; and transferring liquid from the liquid reservoir via the filling hose to an airless liquid container forming part of the liquid dispenser. A system for filling a liquid dispenser, comprising: the liquid filling hose; and a liquid reservoir and/or liquid supply station is also described.

A pipe mount for connecting pipe sections is disclosed. The pipe mount comprises a sliding member movably attached to a plumbing arrangement element. The sliding member extends in the vertical direction of the plumbing arrangement element, and it is vertically movable between an extreme position and a second position. The pipe mount further comprises at least one pipe bracket for securing the pipe sections onto the sliding member. A system and a method for connecting pipe sections are also disclosed.

A fuel dispensing unit includes a fuel conduit including an external annular bead and a locking member including inwardly extending resilient tongues. The locking member is configured to retain the fuel conduit in a locked position and to receive the fuel conduit in an open position. The external annular bead of the fuel conduit causes the locking member to move to the open position when the locking member receives the fuel conduit.
