FLUID TIGHT

A flat sheet or shaped section of rubber compound or rubber textile composite fitted between two metal faces to make a fluid-tight joint. 

A sealing of U-section which is located in a housing so that the fluid pressure tends to expand the flanges of the U into fluid-tight contact with the walls of the housing.

Brain and cerebrospinal fluid (CSF). The capillaries of the cerebral circulation differ from those in most other parts of the body in that they lack the filtration channels between endothelial cells through which substances in the blood nominally gain access to the extracellular fluid. Tight junctions between adjacent capillary endothelial cells, together with their... 

The field of microassembly of microdevices and systems has a long way to go. The addition of the fluidic dimension that is required for microfluidic devices and systems complicates finding a solution, as not only must parts and/or components be joined together mechanically, electrically, and optically as for other systems, but fluid-tight interconnection between parts, devices, or off-chip must all be...

If fluid-tight joints are required, this requirement can readily be achieved with a bonded design. Mechanical joints usually require an extra sealing component such as an O ring. Extra sealing devices can add to the size, cost and overall complexity of the design.
