Abstract

Quick-connect couplings having a sleeve with a tubular tube support mounted therein, an internal O-ring, an external O-ring and a collet are con-figured to retain a tube on the tubular tube support by engaging the tube with the collet. In accordance with one embodiment of the invention, the tubular tube support is retained in the sleeve by engagement with a first internal annual shoulder in the sleeve. The interior O-ring positioned against a second annular shoulder within the sleeve to seal against the tube. The collet resiliently fits within the sleeve to retain the tubular tube support and internal O-ring in place prior to assembly. An external groove is provided in the sleeve for receiving an external O-ring to seal with the bore which receives the coupling. In accordance with another embodiment of the invention, the tubular tube support is staked to a first end of the sleeve by a radially extending flange. The internal O-ring is disposed between the end of the collet and the radially extending flange. An annu-lar trough is provided between the tube support portion of the tubular tube support and the radially extending flange thereof for receiving the tube which is connected by the coupling. Upon pressing the collet into the sleeve with the tube in place, the tube is locked to provide the quick--connect coupling. An external groove in the sleeve receives an external O-ring for sealing with the bore which receiving the quick-connect coup-ling. The bore may be located in a valve body or in a weld bushing welded to a tank such as an air tank. In accordance with a further embodiment, the sleeve has external threads for threading with a standard threaded port.
