Beschreibung
Zusammenfassung:	Disclosed herein are fluidic couplings for high pressure sealing without tools that can apply large amounts of torque. One embodiment of a fitting includes a compression screw, a fluid-carrying tube extending through a bore in the compression screw, a sleeve disposed around the tube, and a seal coupled to the sleeve such that the seal surrounds a distal end portion of the sleeve. This positioning of the seal can facilitate more efficient sealing using less force and creating less dead volume. Such a fitting can be combined, for example, with a driver having a recess formed therein that can surround the compression screw and transfer rotational force thereto. The driver can include outer surface features, such as knurling, that can facilitate a user directly grasping and tightening the fitting. Further, the fitting can include at least one marking used to achieve a desired seal without overtightening.
