A fluid coupler including a ferrule adapter having a body with a receiving bore for receiving a fluid conduit, a stop axially spaced away from the body and configured to engage an end of the fluid conduit, and a connector configured to adjust the axial distance between the body and the stop.

The present invention provides a faucet coupling structure capable of enabling a user to complete the faucet installation by simply inserting the faucet instead of rotating to tighten the faucet, and enabling the user to separate the faucet by holding and rotating the faucet by hand. The user can conveniently install the faucet while adjusting the angular orientation of the faucet to a desired angle. The user can install the faucet by holding and inserting the faucet by hand, and can also separate the faucet by holding and rotating the faucet by hand. As a result, the user can install and separate the faucet without using a tool.

A structure for coupling a faucet or a similar device includes: a faucet with a connecting pipe portion extending there-from; a connecting body with an annular coupling portion formed at one end and connected to a liquid supply source to discharge liquid through the faucet; a fastening nut screw-coupled to the annular coupling portion; a pressing ring coupled to the connecting pipe portion; and a grab ring configured to grab an outer circumference of the connecting pipe portion to have the connecting pipe portion not to be detached from the coupling portion. The fastening nut can be detached from the coupling portion by rotating the faucet and the connecting pipe portion with the engaging configurations of the pressing ring and the fastening nut in engaged position, and an angular position of the faucet can be adjusted to a preferred position in assembly by rotating the faucet and with the engaging configurations of the pressing ring and the fastening nut in disengaged position.

A detachable valve is disclosed. The detachable valve comprises a main body, a connecting pipe and a connecting assembly. The main body is connected to the connecting pipe in a detachable manner through the connecting assembly.

A fluidic connector intended to enable the circulation of a fluid and includes two parts configured to be coupled, each of the parts comprising a channel, the two channels communicating when the two parts are coupled, the fluid being intended to be conveyed by the two channels, and a locking mechanism configured to bear on a first of the two parts and to exert a force on a second of the two parts in order to hold the two parts in position when the two parts are coupled, the locking mechanism passing through an opening in the first of the two parts.

A detachable valve is disclosed. The detachable valve has a main body, a connecting pipe and a connecting assembly. The main body is connected to the connecting pipe in a detachable manner through the connecting assembly. The valve can be installed in small space conveniently as a person can connect the connecting pipe with an external connector firstly and connect the main body with the connecting pipe through the connecting assembly secondly during installation. According to the detachable valve, problems such as customization of existing valve production and complex installation procedure are solved, production simplification, material diversification and scale production can be realized and troubles in production such as customization of one valve needed by one connecting way in the past and material limitation are solved.

A fluid coupler including a ferrule adapter having a body with a receiving bore for receiving a fluid conduit, a stop axially spaced away from the body and configured to engage an end of the fluid conduit, and a connector configured to adjust the axial distance between the body and the stop.

A compression coupling includes a sealing joint for sealingly coupling a pipe to the compression coupling and a restraining joint separate from the sealing joint for restraining the pipe to the compression coupling.

A double containment fitting for connection to a double containment tubing system with an outer, secondary containment tubing surrounding an inner, primary tubing. The fitting includes a fitting body defining a central passageway, the fitting body having a center portion disposed between opposed first and second body ports. The fitting body is configured to receive the tubing system into the first body port. The central passageway has a diameter in the first port selected to allow the secondary tubing into the first body port. A connection system mechanically secures the secondary tubing to the first body port.
