A corrugated pipe connection device is completely coupled by primarily screwing a nut and a socket after interposing a clamping ring between the nut and the socket, inserting an one-side portion of a corrugated pipe, including a groove and a ridge that are successively and alternately formed, into the nut, and secondarily screwing the nut and the socket so that an inner portion of the clamping ring is inserted into the groove of the corrugated pipe and a distal end of the corrugated pipe is pressed. The corrugated pipe connection device is easily coupled in a simplified manner and is capable of achieving enhanced sealing efficiency.

A connector for a hose comprises a first connecting end, a second connecting end and a combining tube. The first connecting end has a main body with a cap shape, a neck portion and an inserting section at a bottom end of the main body, the inserting section has a screw hole connected through the main body and a plurality of engaging protrusions on a circumference of the neck portion. The second connecting end has a threaded section on a circumference thereof, a circular stopping neck internally defining an upper space and a lower space, a plurality of vertical ribs evenly disposed on a sidewall of the lower space, and a plurality of engaging grooves disposed on a top edge of the upper space. The combining tube has a threaded section on a circumference thereof and an enlarged flange at a bottom end.

A hydration system including a fluid reservoir, a fluid path in communication with the reservoir, and a magnetic quick connect interposed in the fluid path is disclosed. A fluid delivery system for a hydration system is also disclosed that includes a magnetic quick connect interposed in a fluid delivery path of the delivery system. The magnetic quick connect can also be used in a wide variety of fluid delivery systems. A kit for forming a fluid delivery system for a hydration system is also disclosed, as are various components of a hydration system.

A rigid entry fitting configured to form a seal between a flexible pipe segment and a sump wall includes a fitting body having an inner surface defining a tapered opening, an insert received in the tapered opening, a shell received in an opening of the insert, a first pair of gaskets between an outer surface of the insert and the inner surface of the fitting body, a second pair of gaskets contacting an inner surface of the shell and opposite ends of the insert, and a nut configured to engage threads on an outer surface of the fitting body. When the nut is threaded onto the threads, the nut presses the shell and the insert into the tapered opening and presses the first pair of gaskets against the inner surface of the fitting body and the second pair of gaskets against the outer surface of the flexible pipe segment.

A clamp device for a barb member having a barbed region for disposing within an end of a flexible tube having an outer surface. The clamp device includes a flexible member including a body having a plurality of finger members compressible between a first resting position and a second clamping position; at least one of the flexible finger members having a radially inwardly extending tooth; the body having a through bore and an outer surface comprising threads; the flexible member being slidable over the barbed region and the outer surface of the flexible tube; a compression member having a body having a through bore and an inner surface including threads; the compression member being slidable over the flexible member; wherein upon threadingly engaging the compression member with the flexible member, the compression member compresses the finger member against the barb member.

A conduit assembly for a separation device is described herein. The conduit assembly includes a first conduit segment, a second conduit segment, and a removable flow control insert or cartridge, which may be easily installed and uninstalled without removing other components of the conduit assembly from the separation device. The flow control insert may be installed within a top opening of the second conduit segment and includes a projection that extends into the conduit assembly and obstructs or restricts fluid flow at the juncture between the first and second conduit segments.

The present invention relates to a band winding type hose clamp which is not released by vibrations or the like generated by an engine or movement of a vehicle, has a calibration function for, when the diameter of a hose is changed by aging due to long-tem use thereof, calibrating the same so as to prevent loss of the clamping force, and has a relatively simple structure. The band winding type hose clamp comprises: a body part engaged with and fixed to one end of a band; a winding part which is rotatably coupled to the body part, into which the other end of the band surrounding the outer periphery of the hose is inserted, and which is rotated by an external force to wind the other end of the band, whereby the band presses and closely contacts the outer periphery of the hose; and a cover part which is hingedly coupled to the body part spaced apart from the winding part while one end of the cover part is engaged with the winding part, and which selectively restrains the rotation of the winding part so as to maintain the elastic force of the band pressing the outer periphery of the hose.
