Patent

CA 2558021

The invention provides quick-connect couplings having a sleeve with tubular tube support, internal O-ring, external O-ring and collet configured to retain a tube on the support. In one embodiment the support is retained by engagement with a first internal annual shoulder. The interior O-ring seals against the tube. The collet retains the support. In another embodiment, the support is staked by a radially extending flange. The internal O-ring is between the collet and flange. An annular trough receives the tube which is connected by the coupling. Pressing the collet into the sleeve locks the tube for quick-connect coupling. The bore may be in a valve body or weld bushing welded to an air tank.
