Abstract: An example fitting includes: a fitting body comprising an exterior annular groove formed and configured to receive a retaining snap ring to couple the fitting body to a fluid line connector; a seal carrier slidably accommodated in the fitting body and having: (i) a first end face, (ii) a second end face opposite the first end face, (iii) a first annular groove formed in an exterior peripheral surface of the seal carrier, wherein the first annular groove is configured to receive a radial seal therein, and (iv) a second annular groove formed in the second end face, wherein the second annular groove is configured to receive a face seal therein; and a spring having a first end fixedly disposed within the fitting body and a second end interfacing with the first end face of the seal carrier such that the spring applies a biasing force on the seal carrier.

Abstract: An example fluid connection system includes: a fitting comprising one or more ears protruding radially outward; a coupling nut comprising at least one helical groove and one or more channels, wherein the one or more channels are configured to allow the one or more ears of the fitting to pass therethrough and reach the at least one helical groove as the coupling nut is slid axially relative to the fitting to mount the coupling nut to the fitting, and wherein the one or more ears are configured to rotationally traverse the at least one helical groove when rotating the coupling nut relative to the fitting, thereby pulling the coupling nut and the fitting toward each other; and an anti-rotation element configured to rotationally couple the fitting to the coupling nut when the coupling nut reaches a predetermined rotational position relative to the fitting.

Abstract: A threaded coupling for ensuring a complete connection between fluid conduits includes a body portion of a fluid conduit, an axially forward sealing surface, a thread, and an interference member. The interference member is disposed on the body portion and is engageable with a portion of another fluid conduit to apply a load on the interference member when the fluid conduits are threadably connected together. The interference member is configured to prevent a complete sealing engagement between the fluid conduits when the load on the interference member is less than a predefined amount, and is configured to allow the complete sealing engagement between the fluid conduits when the load on the interference member meets or exceeds the predetermined amount.

Abstract: A smart torque system includes a fitting comprising a fitting body defining a fluid flow passage from a first end to a second end, and an electronically readable element that is configured to store information about the fitting including at least a torque requirement of the fitting; an electronic reading device that reads the torque requirement from the electronically readable element; and a torque tool that is programmable by the reading device to set a torque to be applied by the torque tool in accordance with the torque requirement. The electronically readable element may include an RFID or NFC storage device, or a patterned code element, that is read by a complementary reading device. The electronic reading device may be incorporated into the torque tool. In another aspect, a fitting includes a fitting body defining a fluid flow passage from a first end to a second end, and an integrated torque sensor.

Abstract: A pressure sensor assembly having a printed circuit board (PCB) with a pressure sensor mounted on the PCB, a side wall engaging the PCB, a membrane, a cavity defined by the membrane, the side wall and the PCB, and a gel or liquid filling the cavity. The pressure sensor assembly may include a fill-hole extending into the cavity through which the cavity may be filled with the gel or liquid. The fill-hole may extend through one or both of the PCB and/or the side wall. The cavity is defined in part by a septum that allows a needle to pierce the septum for filling the cavity with the gel or liquid. A method of forming the pressure sensor assembly may include filling a cavity of the pressure sensor assembly with a gel or liquid through a fill-hole and curing the gel or liquid once in the cavity.
