The present invention provides a novel clutch connector assembly for jointed pipe, threaded pipe, coiled tubing or any threaded or non-threaded pipe for a bottom hole assembly that eliminates the need to use screw threads to mate two pipes or mechanical assemblies, harbors a spring-loaded mechanical locking system in addition in to a pressure-activated, component protectant system, requires no significant tools, other than an Allen wrench or similar screw setting device, permits distributed torque loading, allows for movement in either a clockwise or counter clockwise rotational direction through interlocking castellations and presents a removeable and replaceable valve assembly preventing retrograde hydrocarbon advancement through a drilling pipe.

A pipe joint made of synthetic resin comprises a first opposing surface formed in a joint body perpendicular to the axial direction, and a second opposing surface formed in a union nut that opposes the first opposing surface. An engagement projection is provided in the second opposing surface that projects toward the first opposing surface. An engagement recess is provided in the first opposing surface such that the engagement projection engages with the engagement recess when the union nut has been tightened up to an appropriate position.

A union nut with an annular body portion comprising an interior thread, and a collar portion projecting toward an axis of the annular body portion and including threaded holes. A pipe assembly and a vehicle are disclosed.

A male connecting device for medical use 1 includes a male connector 10 having a cylindrical configuration and a threadedly engageable cylinder 20 rotatably coupled to the male connector 10. A male luer portion 11 of the male connector 10 and a female luer portion 2a of the female connector 2 are joined by turning the threadedly engageable cylinder 20 in a tightening direction T. The male connecting device 1 further includes a loosening prevention mechanism 40 that prohibits rotation of the threadedly engageable cylinder 20 in a loosening direction L with respect to the male connector 10. The loosening prevention mechanism 40 includes ratchet teeth 41 formed in an inner periphery of the threadedly engageable cylinder 20, an elastic leaf 42 formed in the male connector 10 and extends in a circumferential direction and an engageable claw 43 protruded from a free end of the elastic leaf 42 and engageable with the ratchet teeth 41.

In various embodiments, the present invention describes a system that attaches to an existing pipeline, pipe, valve or meter in order to prevent unwanted theft and tampering with fluids and gasses flowing through the pipeline, pipe, valve or meter. In one embodiment of the present invention, the inventive device has two locking halves that mechanically and releasably interact with each other and cover the metering device prior to being locked. In one embodiment of the present invention one housing frame connect with a rectangular base underneath the invention thereby allowing it to lock the meter. In one embodiment of the present invention the electronic signal devices are elevated from the meter thereby preventing accidental dislodging and tampering.

A conduit coupling adapter for securing attaching a conduit to an enclosure is disclosed. The conduit coupling adapter generally includes a first end for receiving a conduit and attaching to it via an adhesive, and a second end coupled to the second end comprises threads and is configured for attaching to an enclosure using a locknut.

A tube fitting including a first coupling member having at least a snap coupling, and a second coupling member having a first quick-connect side having a mating snap coupling disposed at a first end of the second coupling member, and a second quick-connect side configured for threaded engagement disposed at a second end of the second coupling member, the second end being opposite the first end, wherein the mating snap coupling is configured to engage the snap coupling to effect coupling of the first and second coupling member.

Fluid coupling (10), comprising: a first member (20) configured for connection with a first fluid conduit (16); a second member (30) configured for connection with a second fluid conduit (18); a nut (50) disposed at least partially around the first member (20), the nut (50) configured to engage the second member (30); and a sleeve (60) configured to rotate the nut (50) and cause or facilitate engagement between the nut (50) and the second member (30).

A tube fitting including a sleeve member having a circumferential collar portion, the circumferential collar portion including a first tapered surface, a first coupling member having a circumferential engagement flange portion configured to couple with the circumferential collar portion of the sleeve member, and a second coupling member that includes a longitudinally extended sealing portion. The longitudinally extended sealing portion includes a second tapered surface that couples with the first tapered surface so as to circumferentially expand the longitudinally extended sealing portion, when the first tapered surface and the second tapered surface are coupled to each other, and form a fluid seal between the second coupling member and the sleeve member.

A fitting for use with metal, corrugated tubing having peaks and valleys, the fitting includes a nut configured to receive the tubing; a sealing member for placement in a valley of the tubing, the sealing member including a sealing surface; and an adaptor configured to be press fit into the nut, the adaptor including an adaptor sealing surface; wherein upon assembly, the adaptor is press fit into the nut and the tubing is compressed between the adaptor sealing surface and the sealing surface.
