    Abstract: An adapter and coupler assembly has two externally threaded adapters, one left-hand threaded and the other right-hand threaded, and an internally threaded coupler, one end left-hand threaded, the other end right-hand threaded. The coupler threadedly engages the two adapters simultaneously, tightening on both by rotating in one direction, providing a fluid-tight seal. Each adapter has the other end barbed for connection to hose. The coupler and the two adapters each have an external annular flange which is perforated to receive seizing wire or wire ties to prevent the components from unthreading. The coupler has a multi-sided barrel at its center, and the adapters have a multi-sided nut portion, to provide purchase by a wrench-type tool. Each component may also have a mark indicating the starting point of the thread, to facilitate engagement of the components. The assembly is especially useful in fluid-carrying systems of boats, recreational vehicles, and campers.

    Abstract: An intrinsic gauging device for a ferrule type tube fitting of the type having a coupling nut, a coupling body and at least one ferrule, includes a precisely formed marking on the coupling body that is visually perceptible when the coupling is in a finger tight position, and that is covered or visually imperceptible or otherwise has a predetermined relationship with the coupling nut when the fitting has been initially pulled-up. In a preferred form, the marking is realized as a precision groove or recess machined into a surface of the coupling body. The groove can be made more easily visually perceptible such as by roughening or knurling the surface, or coloring the surface, for example. The groove defines an edge at a precise position that corresponds to a predetermined axial displacement of the nut relative to the body for initial pull-up. The marking may also be formed with a precise dimension such as an axial length to provide a second edge that corresponds to a predetermined axial displacement of the nut relative to the body beyond initial pull-up for fitting assemblies that are remade.

    Abstract: A fluid coupling includes various features. One feature is a disconnect tool that may expand a lock ring from engagement with a lock shoulder to permit the male half and female half to be separated. Another feature is to utilize geometry and structure whereby a leak would occur to indicate the condition of wear within the coupling while the coupling halves remain mechanically coupled. A further feature is to provide connection verification structure to assure that a complete connection of the male and female halves has been made. A still further feature is to provide an anti-rotational sleeve which would selectively prevent and permit relative rotation between the male half and the female half.

    Abstract: The torque confirmation fitting is used for coupling one section of tubing to another and includes a fitting body, a fitting nut, and a torque confirmation portion. The fitting body has a nose section that supports an end of one of the sections of tubing. The torque confirmation portion has a collar portion and one or more prongs. The fitting nut is operably joinable to the fitting body and engageable with the torque confirmation portion. To operate, the non-supported end of the tubing is inserted through the torque confirmation portion and the fitting nut. The fitting nut is then joined to the fitting body and in doing so engages the torque confirmation portion. The continued joining of the fitting nut to the fitting body causes the prong of the torque confirmation portion to provide a visual indication that the fitting nut has been sufficiently, tightly joined to the fitting body.

    Abstract: Connectors (33, 45, 52) are connected to each other when joints (15) that connect tubes (14) and pipes (20, 40) to each other are mounted thereon. The connectors (33, 45, 52) are disconnected from each other when the joints (15) are removed therefrom. A detection circuit (8) detects an electrical disconnection between terminals (70) and (33) in the connectors (52) and (33B), respectively and outputs an alarm signal to inform an operator that the joint (15) has not been installed on the tube (14) or the pipe (20, 40).

    Abstract: A pipe fitting includes a slider disposed in an insertion hole of a main body so as to be axially moved and includes a pressed portion which a falling-off preventing flange of a pipe abuts so that the slider is pressed axially when the pipe is inserted into the insertion hole. A fitting checker includes a pair of spreading legs having respective claws, the fitting checker being detachably attached to the main body so that the legs hold the main body. The claws engage the body and the slider so that the fitting checker is not allowed to be detached from the body when the legs are closed. The legs are spread so as to release the claws from engagement with the body and the slider so that the fitting checker is allowed to be detached from the body. Releasing protrusions are formed to protrude from inside portions of the legs of the fitting checker, the releasing protrusions being pressed so that the legs are elastically deformed in respective opening directions. A pressing portion is formed on the slider so as to press the disengaging protrusions of the fitting checker to spread the legs of the latter when the pipe is inserted into the insertion hole to assume a normal fitting position so that the slider is displaced to a normal thrust position.
