This safety clean-out cap system provides for the removal of water and debris from drains. It consists of a flow channel that is mounted within the opening of a clean-out cap. The flow channel is diametrically opposed to the top surface of the clean-out cap and bends at a 90-degree angle just below a rectangular recess. The rectangular recess has a grab portion that cooperatively receives a tool. Additional embodiments of the safety clean-out cap system include clean-out caps having channel extensions and a square-shaped channel. The channel extensions extend at a 180-degree angle from the clean-out cap and have a plurality of longitudinal rails and longitudinal plates that further facilitate the removal of the clean-out cap from drainpipes. The clean-out cap and the additional embodiments are attached to fittings, pipe sections and hose sections in order to regulate the flow of water and debris from a drain.

The present disclosure provides a pipe coupling that includes a coupling body, a first pack joint nut, and first and second sleeves. The coupling body is made of a first metal material and the first pack joint nut is made of a second metal material. The first pack joint nut is configured to receive a portion of a first pipe. The pipe is made of a dissimilar metal material to the first and second metal materials of the coupling body and the first pack joint nut, respectively. The first sleeve is configured to line at least a portion of an inner periphery of the coupling body. The second sleeve is configured to line at least a portion of an inner periphery of the first pack joint nut. The first and second sleeves are made of non-metallic materials, and serve as physical non-metallic barriers between the first/second metal materials of the coupling/first pack joint nut, and the dissimilar metal material of the first pipe.

A lightweight quick connector system that is a more unitized, installation and dismantling structure and method for joining the ends of straight grooved pipe that uses o-ring fluid sealing. The connector system includes a grooved pipe receiving structure for support and stabilization of the o-ring sealing structure. The quick connector system also has the capability to operate as a size adapter for grooved pipe of different sizes and has the capability to act as a fitting adapter to enable interfitting of a grooved pipe to another size and type of pipe.

A catch basin comprising a circular collar with a first internal diameter, configured to receive a downwardly extending circular drain pipe. A sump for receiving downward water flow from the circular collar is integrally formed with the circular collar, the sump being shaped to include two differently shaped cylindrical portions. The shape of the sump facilitates both the ability to stack multiple units of the sump one upon another for packaging, shipping, and sale. The shape of the sump also facilitates the ability to remove an internal stub attached to the sump, to improve water flow in the remaining structure.

A drain fitting for use in an irrigation system for draining water from the irrigation system, regardless of pipe size in the irrigation system, generally includes a grip portion and a neck coupled to the grip portion. The neck defines a first engagement portion having a first diameter, for coupling the drain fitting to a pipe of the irrigation system having a diameter corresponding to the first diameter of the first engagement portion, and a second engagement portion having a second diameter, different from the first diameter, for coupling the drain fitting to a pipe of the irrigation system having a diameter corresponding to the second diameter of the second engagement portion.

The invention includes an adapter for attachment to a paint applicator including a substantially cylindrical body having a fluid channel extending through the cylindrical body; a male thread formed on an outer surface of the cylindrical body and configured for removable attachment to the paint applicator; a first female thread extending into the fluid channel from a first end of the cylindrical body; a second female thread extending into the fluid channel from a second end of the cylindrical body; and a transfer channel extending between the first female thread and the second female thread so as to form the fluid channel.

A hydraulic fracturing system for fracturing a subterranean formation includes an electric powered pump having an inlet and an outlet, the outlet coupled to a well associated with the subterranean formation and powered by at least one electric motor. The system also includes a fluid source, coupled to the inlet of the electric powered pump, the fluid source providing a slurry for injection into the subterranean formation. The system further includes a hose extending between the fluid source and the electric powered pump, the hose being flexible and having a first diameter. The system includes a fitting between the hose and the electric powered pump, the fitting having a first end for receiving the hose at the first diameter and a second end for coupling to the electric powered pump at a second diameter, the second diameter being larger than the first diameter.

A preassembled coupling for joining pipe elements has segments surrounding a central space with cusps which engage lobes of a seal to maintain the segments in spaced apart relation in a preassembled state. While the coupling is in the preassembled state the pipe elements may be inserted into the central space without disassembling the coupling, and portions of the seal adjacent to attachment members on the segments seat within a channel defined by the segments between the cusps, while portions of the seal between the attachment members are further from a back surface of the channel.

An indicator assembly includes a fastener defining a first end, a second end opposite the first end, and an axis extending from the first end to the second end; a first indicator positioned radially outwardly of the fastener relative to the axis of the fastener; and a second indicator positioned radially outwardly of the fastener relative to the axis of the fastener, wherein the second indicator is axially in between the first indicator and the second end of the fastener upon the fastener being oriented in a first position, and wherein the second indicator is radially inwardly or radially outwardly of the first indicator upon the fastener being oriented in a second position.
