Abstract
In some examples, a capillary connection fitting may include a screw drive, and a screw rotatable by the screw drive and insertable in a port. A spring-loaded disc may be operatively disposed between the screw drive and the screw, and rotatable by the screw drive to impart, by the screw, a sealing axial force to seal a capillary tip of a capillary against a port ground of the port.
