A push-to-connect fitting is provided. The push-to-connect fitting includes a connector body, a sealing member, a grab ring, a cartridge, a retainer sleeve, a plurality of latches, and an interference portion. The sealing member is configured to form a sealing engagement with a fluid conduit. The grab ring includes a plurality of teeth configured for coupling to the fluid conduit. The retainer sleeve is received over at least part of the cartridge and is received over at least part of the connector body. The plurality of latches are located on the retainer sleeve and are configured to secure the retainer sleeve to the connector body to facilitate retention of the sealing member, the grab ring, and the cartridge. The interference portion is configured to engage the retainer sleeve to substantially prevent rotation of the retainer sleeve relative to the connector body.

A nozzle cap spacer for a hydrant nozzle cap includes a spacer body defining an outer edge and an inner edge, the inner edge defining an opening formed through a center of the spacer body; and a leak path notch formed in the spacer body, the leak path notch extending radially inward from the outer edge of the spacer body.

A magnetic quick connect for a fluid delivery system includes a male coupling member and a female coupling member. The male coupling member defines a first outer fluid communication path and includes a first magnetic material. A first inner member is disposed within the first outer fluid communication path and defines a first inner communication path. The female coupling member defines a second outer fluid communication path and includes a second magnetic material. A second inner member is disposed within the second outer fluid communication path and defines a second inner communication path. The male and female coupling members are detachably held together by an attractive force between the first and second magnetic materials such that the first and second outer communication paths are held in fluid communication, and the first and second inner communication paths are held in fluid communication.

A foreign material exclusion device that is adapted to seal an area of a construction, such as a tube or pipe or other cavity, from foreign material or debris temporarily, wherein the device includes a cylindrical plug that has a plurality of resilient bodies for holding the device within a particular construction. The bodies are substantially planar, and semicylindrical in shape wherein two bodies are utilized. A flexible cover includes a first pouch which contains a first body therein and desirably a second pouch of the cover contains a second body therein, with the cover having a hinge between said first and second pouches. When the device is not in use, the bodies can be folded against one another in a closed position until they are inserted into a tube or pipe whereupon they can be opened to an open position and generally form a disk having a snug, fitted connection with a wall of the tube or pipe.

A nozzle cap spacer for a hydrant nozzle cap includes a substantially planar spacer body defining an outer body edge; and a resilient spacer spring arm extending from the outer body edge at a proximal arm end, the spacer spring arm configurable in an extended orientation and a compressed orientation, the spacer spring arm biased to the extended orientation; wherein, in the extended orientation, the nozzle cap spacer defines a substantially oblong shape, and in the compressed orientation, the nozzle cap spacer defines a substantially circular shape

A pipeline network includes at least one housing comprising a riser and a pipeline connector, the housing adapted to receive a device configured to interact with fluid flowing through the pipeline connector. The riser is provided with a riser closure member that is attachable removably to the riser, and a seal adapted to provide a fluid tight seal between the riser and the riser closure member.
