ABSTRACT:
A Vari-Stage Coupling device that accomplishes the goal of coupling different styles of tubing in one device. The coupling device allows the user to incorporate different sizes of tubing into a single fitting decreasing the confusion as to which part fits with which tubing and decreasing his time looking for the right fitting. The coupling device also allows the user to need to use only one device for most all of his coupling needs.
