There may be provided a connector for a liquid container. The connector may include a connector body, and a through-hole for fitting on a neck portion of the liquid container. The connector may further include a restraining arrangement positioned proximal to the through-hole. The restraining arrangement may include a first restraining member and a second restraining member extending towards a central axis of the connector body. The first restraining member may have a distal end that extends further than a distal end of the second restraining member. The distal end of the first restraining member may engage the neck portion of the liquid container at a first position, and the distal end of the second restraining member may engage the neck portion of the liquid container at a second position. The connector may further include a connector-to-key-interface arrangement configured to mate with a corresponding surface of a key member.

The present disclosure generally relates to flexible drainage trap assemblies and methods for constructing and installing such drainage traps. In one exemplary embodiment, a flexible drainage trap assembly includes a plumbing fixture connector, a discharge joint, and a trap portion connecting the plumbing fixture connector and discharge joint. The trap portion is shaped in such a way that it is operable to retain a pool of water inside the trap portion. The disclosed flexible drainage assemblies include a flexible portion that has a substantially smooth inner surface.

A gooseneck pipe includes a first pipe half having a first radiused centerline curve, and a second pipe half fixed to the first pipe half and having a second radiused centerline curve. The first and second pipe halves define a flow path. Cross-sectional diameters of the first and second pipe halves vary along the flow path. The varying diameters of the first and second pipe halves serve to mitigate pressure losses due in part to Dean vortices or secondary flow patterns in the flow path when a fluid is turned in the gooseneck pipe.

A ceramic-backed elbow featuring an extended chamber which alters the flow of fluent through the elbow section. This chamber is lined with a ceramic material and ceramic tiles. The remainder of the elbow is similarly coated with a ceramic mixture. The elbow could be placed into a coating pan upon the tiles being adhered to the elbow, and the entire elbow may be coated with an abrasive-resistant coating. A thin metal skin may then be applied over the entire surface of the coating.

A flow conditioning assembly comprising an integral elbow flow conditioner and a downstream flow conditioner. The elbow flow conditioner includes a pipe elbow with one or more flow conditioning elements. Each flow conditioning element includes one or more turning guides. Each turning guide is generally circular and radially spaced from one another and an inner surface of the elbow. Spaced vanes maintain the radial spacing of the turning guides. The vanes divide the radial space between the turning guides and pipe elbow into a plurality of flow channels that turn in generally the same direction as the inner surface of the pipe elbow. The downstream flow conditioner comprises a flow conditioning structure within a pipe element. The flow conditioning structure includes one or more flow guides of generally circular form radially spaced from one another and the pipe element. Spaced support vanes maintain the radial spacing of the flow guides.

A double vented transition elbow can be used when venting a variety of applications, such as for baseboard heaters and hot water heating systems. The double vented elbow allows venting in one orientation or in a different orientation when the elbow is rotated. One end of the elbow couples to copper tubing, while the other end of the elbow couples to PEX tubing. Thus, the elbow not only allows for venting in two different orientations, it also allows for the transition from copper to PEX tubing within the same fitting.

On example provides a containment sleeve for a pressurized piping system including a main body comprising a pliable fabric extending in longitudinal and transverse directions. The main body includes an exterior major surface and an opposing interior major surface, first and second opposed transverse edges, first and second opposed longitudinal edges, and a number of pleats extending from the interior major surface, each pleat having opposing sides of the longitudinal pleat being sewn together with breakaway stitching at a base of the pleat at the interior major surface. A number of transversely extending straps disposed on the exterior major surface between the first and second longitudinal edges, the straps to secure the main body about a portion of the piping system with the interior major surface facing the piping system.

A sprinkler configured for engagement with a coupling, the sprinkler including a raised lip end; and a distal end disposed opposite from the raised lip end, the sprinkler defining a raised lip between the distal end and the raised lip end, the sprinkler defining a groove between the raised lip and the distal end.
