Assembly for connecting a branch line to a fire-sprinkler head, and for adjusting longitudinal and horizontal position of the sprinkler head. The assembly may include: a first-pipe section, a second-pipe section, and a third-pipe section. First-pipe section has telescoping lower and upper pipes configured to travel axially relative to each other upwardly and downwardly along a longitudinal axis. Second-pipe section has telescoping right, and left pipes configured to travel axially relative to each other along a horizontal axis. Third-pipe section is between first-pipe section and second-pipe section, and is curved. First-pipe section is configured to engage a sprinkler head and permit the sprinkler head to travel longitudinally upon telescopic adjustment of the lower and upper pipes. Second-pipe section attaches to the sprinkler-branch line, and permits the sprinkler head to travel horizontally upon telescopic adjustment of the right and left pipes with respect to each other.

A liquid medium delivery device has: first and second rigid pipes configured to receive flowing liquid medium from a pump. The first rigid pipe has a first curved portion. The second rigid pipe has a second curved portion. The curved portions are at least partially nested. An actuator is connected to the first rigid pipe or the second rigid pipe or both the first and second rigid pipes. The actuator is operable to move either the first rigid pipe or the second rigid pipe so that either the first curved portion or the second curved portion moves along a common arc of both the first curved portion and the second curved portion. The liquid medium delivery device has an outlet through which liquid medium, for example liquid manure, can be pumped.

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.

An improved quick connector with code verification is provided. The quick connector includes a connector body, a connector sleeve, and a sliding lock latch. The connector body includes a verification indicia on its outer surface, and the connector sleeve is movable over the connector body and includes an indicator window that aligns with the verification indicia. The sliding lock latch is moveable from an unlatched position to a latched position through transverse openings in the connector sleeve and the connector body. The sliding lock latch includes first and second wing elements to prevent clockwise and counter-clockwise rotation of the connector sleeve relative to the connector body. The sliding lock latch also includes a locking tab on its outer surface to prevent retraction of the connector sleeve from the connector body.

A quick-fitting pipe fitting assembly for coupling with at least one pipe element includes a pipe fitting body, at least one coupling unit, at least one gasket and a plurality of connecting elements. Each coupling unit includes a fixed coupling element integrally extended from the pipe fitting body and a movable coupling element, the gasket disposed at the coupling unit, the connecting elements movably connect the fixed coupling element with the movable coupling element, wherein the at least one coupling unit is adapted for being preassembled with the at least one pipe element and can be fastened by at least one fastening element that is capable of being operated to fasten the movable coupling element with the fixed coupling element.
