1. An air chuck comprising: a body comprising: an output port; an interface port, wherein the body defines a first passageway that extends between the output port and the interface port; and an input port that defines a second passageway that is in fluid communication with the first passageway, the input port being configured for attachment to a pressurized fluid source to facilitate delivery of pressurized fluid through the second passageway and to the first passageway; and a valve core interface slidably coupled with the body and slidable between an extended position and a retracted position, the valve core interface comprising: a shaft including a proximal end and a distal end, the distal end being at least partially disposed in the first passageway; and a knob coupled with the proximal end of the shaft, wherein: the shaft is rotatably coupled with the body and is selectively rotatable in either a tightening direction or a loosening direction via rotation of the knob; the distal end of the shaft comprises a grasping feature that is configured to grasp a valve core of a valve stem; and the body defines at least one viewing window disposed along the first passageway for viewing of the shaft from outside of the body; and an internal sleeve that is disposed in the first passageway and surrounds at least a portion of the shaft, the internal sleeve being formed of a substantially transparent material.
