Abstract: A quick-connect sanitary fluid connector system provides for connection of a sanitary fluid system to an industry standard, flanged sanitary fitting. The standard fitting is placed in abutting relation to a sanitary gasket and to a first fitting of the quick connector, and at least two eccentric cams operated by cam levers press against the back surface of the standard connector flange, thereby applying pressure to the juncture and forming an abutted sanitary seal which avoids fluid entrapment within the connector. The joining pressure can adjustable by threaded rotation of the first fitting within a connector body. The cam levers can include locking holes and pins for locking the levers in their locking positions. Insertion of the standard fitting can automatically open the cams, and springs can automatically return the cam levers to their locking positions. Spring retracted telescoping cam levers can be automatically latched in their locking positions.

Abstract: Positive locking device for components of snorkels and other equipment such as diving regulators, buoyancy compensator hoses and the like. The locking device in a preferred embodiment comprises a hard plastic C-shaped ring or clamp which is preferably mechanically and/or chemically bonded into a soft plastic component connector during molding of that component. The ring or clamp provides an effective locking feature which prevents inadvertent demating of components during a dive or other activity that could otherwise result in a dangerous loss of function. An additional embodiment of the invention provides an optional indexing feature which serves the useful function of audible and tactile feedback during adjustment of components having the locking device.

Abstract: A metal ring gasket provides a high-pressure temperature tolerant metal-to-metal seal between subcomponents of a threaded union. The metal ring gasket is received in an annular cavity formed between mating surfaces of the subcomponents of the threaded union. The metal ring gasket is capable of maintaining a fluid seal even at very high temperatures resulting from direct exposure to fire. At high fluid pressures the metal ring gasket is energized because hoop stress induced by the fluid pressure forces the metal ring gasket into tighter contact with the subcomponents of the threaded union.

Abstract: An expandable tubular connection includes a pin member and a box member. The pin member includes a pin thread formed on a small step and a large step and a first seal surface formed between the small step and the large step. The box member includes a box thread formed on a small step and a large step and a second seal surface formed between the small step and the large step. The pin thread and the box thread are wedge threads. Upon a selected make-up of the pin member with the box member a selected gap exists between the first seal surface and the second seal surface. The gap is selected such that, when plastically radially expanded by a selected amount, a seal is formed between at least a portion of the first seal surface and the second seal surface.

Abstract: A modular connector system that permits changes to the connector, for example changes in the type of connection interface that is used and/or changes in the type of actuator that is used to actuate the connector. By making parts of the connector changeable, the connector can be changed so as to be able to connect to different fluid systems. This eliminates the need to have separate connectors for different fluid systems.
