ABSTRACT:
A quick connect fitting for tubing which can be inserted into a pre-assembled fitting where it will become sealed and locked against pull-out. A main fitting body has an open-ended recess in which is located a movable piston to seal against the body and an inserted tube. The piston wedges over a conical extension on a sealing gland retained by a snap-on cap, the gland and the cap having complemental spherical surfaces to allow swivel movement of the tube without disturbing the seal in the tube. A locking ring retainer grabs the tube annularly and bears against the piston to resist pull-out.
