Fluid fitting

A fluid fitting, comprising:

• a nut including an inner surface or flange;
• a sleeve including a flange;
• and
• a union having threads and a stop, the union including:
• a gauge diameter having a center point and an axis of rotation, the axis of rotation defining a plane perpendicular to the union and including the center point of the gauge diameter;
• and
• a point of intersection defined by the threads of the union and the plane perpendicular to the union, a position of the stop is determined according to an angle from the point of intersection;
• wherein the nut includes a stop corresponding to the stop of the union, the corresponding stops contact or engage with each other when a limit of a degree to which the nut is able to be screwed onto the union is reached, and the inner surface or flange of the nut engages the flange of the sleeve such that axial movement of the nut in at least one direction causes axial movement of the sleeve.
