<p>A water purifier includes a quick-connect tube connector, including a port having a collet, an O-ring seal (28), and a support ring (29) between the collet (63) and the seal (28) . The collet axially receives a tube (24) for water passage. The support (29) is preferably a ring that limits radial movement of the tube (24) off the axis (26), and may be, for example, an L-shaped ring or a flat ring. In an easy to assemble embodiment, the tube (24) is received along the axis (26) of the port in a first reference direction, and the connector is assembled by inserting, in sequence, a support ring (29), an O-ring (28), and a plug into the port along the axis (26), but in a direction opposite the first direction. The plug may be held in place by adhesive or conventional welding. To complete the assembly, a collet (63) is inserted into the port in the first direction, and a tube (24) is then connected to the water purifier by urging the tube (24) through the collet (63) in the first direction. The tube (24) is thereby gripped by the collet (63), supported by the support ring (29), sealed by the O-ring (28), and stopped against the plug. Weeping at the port thereby may be eliminated by maintaining axial relation between the tube (24), the seal (28), and the collet (63).</p> |
