Abstract: A quick connect structure having a fitting connector, a connector, and U-shaped positioning snap pin. The fitting connector has a connector part, a fitting connector body part coupled to the connector part, and a fitting part coupled to the fitting connector. The connector part, the fitting connector body part, and the fitting part define a fitting hole extending therethrough, and the fitting part defines positioning groove, a longitudinal snap hole, and a side snap opening in communication with the longitudinal snap hole. The connector has a connection end, a connector body part coupled to the connection end, and a positioning bump. The connection end and the connector body part define a duct hole extending therethrough, the connection end defines a positioning snap groove, and the fitting connector is configured to accept the connection end in the fitting hole. When the connection end is fully inserted into the fitting connector, the positioning bump is located in the positioning groove, and the longitudinal snap hole is aligned with the positioning snap groove. The U-shaped positioning snap pin has a pin base, a pin body part coupled to the pin base, and a snap protrusion coupled to the pin body part. The U-shaped positioning snap pin is configured to be partially inserted and fully inserted into the longitudinal snap hole; when partially interested, the snap protrusion engages the side snap opening and the connector is able to be inserted into the fitting connector; and when fully inserted and when the connector is inserted into the fitting connector, the pin body part engages the positioning snap groove and the snap protrusion engages a longitudinal snap hole exit.

Abstract: An improved quick connector is provided. The quick connector includes an assembly check that is partially received within an input end of a connector body. The assembly check includes a pull tab and a shielding portion. Upon insertion of a male connector within the input end of the connector body, assembly check retracts from the input end of the connector body and can be manually removed via the pull tab. Once removed from the connector body, a machine readable verification indicia can be read. The verification indicia is visible on an underside of the shielding portion or visible on the connector body once the shielding portion is removed.

Abstract: A fluid fitting includes a nut, a sleeve, and a union. The union and the nut may include corresponding stops and corresponding markings. Corresponding stops and corresponding marking may engage with each other when the nut is sufficiently connected with the union. A method of connecting a fitting includes connecting a sleeve of the fitting with a nut of the fitting, connecting the nut with a union, rotating at least one of the nut and the union until a stop of the nut engages a stop of the union, restricting over torque via the stop of the nut and the stop of the union, and verifying a sufficient connection if first markings of the nut align with second markings of the union.

Abstract: A coupling has first and second segments attached to one another end to end surrounding a central space for receiving pipe elements. A spring assembly attaches the segments at one end and an adjustable attachment assembly attaches the segments at the opposite end. The spring assembly biases the segments away from one another sufficient to permit insertion of the pipe elements into the central space while the segments are attached to one another. The coupling may include a split ring toothed retainer for coupling plain end pipe elements, or it may have arcuate keys which engage grooved or shouldered pipe elements.
