A faucet spout mounting system including a faucet spout tube, an inner adapter, and a bushing. The bushing is positioned radially intermediate the outer spout tube and the inner adapter. The inner adapter and the bushing engage to push flexible arms on the bushing against the outer spout tube, thus holding the bushing in place and compensating for tolerances in the spout mounting system.

A tube fitting for connection to a tube includes a main body structure and a tube liner. The main body structure is configured to receive an end of the tube and fluidly connect the tube to another component. The tube liner is positioned at least partially within the main body structure and is configured to extend into the tube. The main body structure and the tube liner are configured such that, when the tube is fully inserted into the tube fitting, the end of the tube is positioned at a predetermined depth within the tube fitting, and the main body structure and the tube liner cooperate together to provide an audible indication to indicate that the tube has been fully inserted into the tube fitting.

A release clip for a tube connector is provided for use in a system with flowing fluid. The tube connector includes a housing with an opening through which the flowing fluid passes, and is arranged for secure and sealing connection with a tube which is inserted in the connector. In the housing there is mounted a circular gripper ring which grips the tube. The release clip has a tubular circular release body which is split along its longitudinal axis and includes an integral hinge, thus enabling it to be mounted around the tube that has to be released and the length of the release body in its longitudinal direction is at least equal to the distance extending from the housing's opening to the gripper ring.

A pipe joint is equipped with a body, and an attachment and detachment mechanism by which a fluid tube is mounted detachably with respect to the body. A pawl of a chuck that constitutes the attachment and detachment mechanism includes a stopper member that abuts against an outer circumferential surface of the fluid tube, and piercing members, distal ends of which project more toward a side of the fluid tube than the stopper member and pierce into the outer circumferential surface of the fluid tube.

A tube connector for attachment to an end of a tube of a pressurized fluid system has a housing, a main sealing element, a gripping element and a cone element. The main sealing element is arranged for sealing an inner surface of the housing to an outer surface of a tube. The gripping element comprises a gripping edge for engaging with an outer surface of a tube. The cone element limits a movement of the grip-ping element. The tube connector further has an integrated release element. The release element has a tubular part, a top part and an environmental sealing. A release edge of the tubular part engages with the gripping element and the environmental sealing is adapted for sealing a receptacle formed in the housing of the environment.

A sealing structure includes an inner pipe, an outer pipe, and a sealing ring, where the outer pipe is detachably sleeved on the inner pipe, a slot for inserting a pipe is formed between an inner wall of the outer pipe and an outer wall of the inner pipe, and the outer wall of the inner pipe is provided with a sealing groove for placing the sealing ring; the sealing ring includes a main body provided with a lip; the sealing groove includes a first sealing groove and a second sealing groove, the first sealing groove and the second sealing groove are stepped; the bottom of the lip fits the bottom of the first sealing groove; and the bottom of the main body fits the bottom of the second sealing groove.

The main body structure and the tube liner are configured such that, when the tube is fully inserted into the tube fitting, the end of the tube is positioned at a predetermined depth within the tube fitting, and the main body structure and the tube liner cooperate together to provide an audible indication to indicate that the tube has been fully inserted into the tube fitting.

A polymer pipe has a length between a first end and a second end. The length and the first end have a first diameter and the second end is a belled end having a second diameter larger than the first diameter. An insert device is received within the second end and has an annular body and a spline groove formed in the annular body and facing radially inward. The insert device is pre-installed in the belled end during the belling process.

A push to connect fitting includes a body member adapted to receive a conduit end, a conduit comprising a first end that can be axially inserted into the body member and a conduit gripping device attached to an exterior surface of the conduit, and a retainer that retains the conduit in place when said conduit is fully inserted into the body member. Additional embodiments include providing a seal with the fitting that seals the exterior surface of the conduit, an optional load retaining sleeve for the conduit gripping device, and an optional gimbal. The push to connect aspect may be realized in the form of a single action unthreaded mechanical connection.
