An adaptor assembly is disclosed in two embodiments. Each embodiment is for connecting a tubing to a fitting of different size. The alternate embodiment is similar to the first embodiment except that it cooperates with a male fitting as opposed to a female fitting. In the embodiment for connection to a female fitting, a hollow threaded nut drives a tapered spool into a tubular seat, and the tubing is placed on the interior of the nut, spool and seat. All of this is placed in a hollow threaded adaptor which abuts a larger tapered spool, all of which threads into the female fitting. When the components are threaded together, they squeeze and clamp the tubing. The tubing, once clamped, is held securely and cannot be pulled free. The threaded adaptor has a wall thickness enabling it to mate with a fitting of any suitable size. The male counterpart equipment is similar in construction except that the adaptor coupling is provided with two sets of threads arranged respectively at countersunk internal axial portions to receive a male fitting thereinto.
