摘要： A pipe connector having a body with a tubular part to seal with a pipe. The tubular part has an outer face with a projecting feature to seal with the pipe. A collet is fixed to the body and spaced from the tubular part to form a cavity for the pipe. A locking cap is captive on and screwed onto collet to deflect the collet onto the pipe and the pipe onto the tubular part to seal between the body and the pipe. The collet has through slots at its distal end allowing the pipe to be visible when the connector is locked and unlocked. The inner diameter at an open end of the collet is optionally greater than the inner diameter of the distal part that receives the pipe. A method of forming the connector is also disclosed.

摘要： A pipe joint contains a body having a fluid passage in the interior thereof, a tightening cap screw-engaged with an end of the body for connecting a tube thereto, and an indicator ring interposed between a stopper of the body and an end of the tightening cap. The indicator ring is equipped with a flat section and an inclined section, which is inclined with respect to the flat section, and is formed with a smaller diameter than an outer circumferential surface of the tightening cap. When the tightening cap is screw-rotated to thereby connect the tube, as a result of the inclined section being pressed and deformed by movement of the tightening cap, the inclined section projects radially outward with respect to the outer circumferential surface of the tightening cap, whereby a tightened condition is visually confirmed by the outer edge of the indicator ring.

摘要： A joint is connected to a tube and includes a joint body, nut, and ring. The joint body has a tube coupling part and a main body thread part. The nut has a nut thread part and a constricted diameter part. The ring is arranged in a space radially inward of the nut thread part. The ring abuts an abutted part of the nut. The ring has a Young's modulus greater than the tube. The ring has a curved surface part at least at a radially inward portion of the ring axially on the joint body side, the curved surface part bulging radially inward of the ring and axially toward the joint body side. A maximum thickness of the ring in a radial direction is defined as 2r, an axial length of the curved surface part of the ring is defined as h, and α=h/r being 0.5 to 1.2.

摘要： A pipe connecting device having a joint body including a fitting cylinder to which a flared synthetic resin-made tube is to be externally fitted, an external thread formed on a radially outward side of the fitting cylinder; and a union nut including an internal thread screwed with the external thread, and a tube pressing portion that presses a diameter changing portion formed between a flared portion in the tube, and a non-flared portion, in the direction of the axis. In a fastening completion state in which the tube pressing portion is caused to press the diameter changing portion by a screw advancement of the union nut, the screw advancement being produced by screwing the internal thread to the external thread, positions of a basal end of the external thread and a tip end of the union nut in the directions of axes coincident with each other.

摘要： A resin-made pipe joint with enhanced sealing property between a joint body and sleeve. A sealing portion which seals between an inner circumferential surface of an inserting portion of a sleeve and an outer circumferential surface of an inner cylinder portion is formed by press-inserting an inserting portion into a groove portion of the joint body. When the inserting portion is press-inserted into the groove portion, a space is formed between a body cylinder portion located opposite to an opening portion of the groove portion in the axial direction, and the projection end of the inserting portion. After completing press insertion of the inserting portion into the groove portion, in a section including axis of the inner cylinder portion, a region in the outer circumferential surface of the inner cylinder portion facing the space forms an angle of 5° to 15° to the axis of the inner cylinder portion.

摘要： An anti-rotation device for preventing a hydraulic connector assembly from leaking. Various embodiments of the anti-rotation device provide a mechanism whereby threadably engaged connectors, such as compression fittings, are permitted to rotate only a fraction of a turn after loosening. For many applications, the limited degree of loosening is sufficient to prevent the onset of leaking. Structurally, the anti-rotation device can include a band that is secured to a female nut of a hydraulic connector. Protrusions extend laterally from the band and engage with a stop tab on the male body of the hydraulic connector assembly, thereby limiting rotation of the female nut that would otherwise cause leaks.

摘要： 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.
