ABSTRACT:
This device is an adapter for joining non-threadable flexible tubing to other piping in both fluid-tight and mechanically positive relation. It has serrated chuck jaws encircling the tubing which grip and depress the wall of the tubing into a peripheral hollow in a supporting sleeve within the end of the tubing, when relative rotation is effected between the body of the adapter and a bushing threaded thereinto and surrounding the tubing. A gasket is pressed into sealing relation with the tubing and the adapter.
