  • Patent number: 9989175
    Abstract: An exemplary adapter configured as a transition between a fitting and a fluid system component. In one exemplary embodiment, the adapter is configured as a transition between a compression fitting and a fluid system component. The adapter comprises a body portion, a compression portion, and a flange portion. A first end of the body portion is inserted into a port of the compression fitting and the compression portion compresses a resilient seal against a sealing shoulder of the fitting. A nut of the compression fitting engages the flange portion of the adapter to connect the adapter to the compression fitting. A second end of the body portion is connected to a fluid system component. The adapter provides a fluid tight connection between the compression fitting and the fluid system component without using a gasket ring or a locking ring of the compression fitting.

  • Publication number: 20080106092
    Abstract: A fluid coupling that attaches to a threaded component. The body portion of the fluid coupling has an end that defines a flow path along an axis and includes a first seal groove. An extension of the fluid coupling is mounted onto the end. The extension rotates about the axis and moves axially relative to the body portion. The extension includes a threaded tip for threadably coupling the threaded component. The extension also has a radially extending face adjacent the tip that includes a second seal groove. A first seal of the fluid coupling is positioned in the first seal groove and is adapted to provide a seal between the body portion and the extension. A second seal of the fluid coupling is positioned in the second seal groove and is adapted to provide a seal between the extension and the threaded component.
