Abstract: A water purifier includes a port having a collet, an O-ring seal, and a support between the collet and the seal. The collet axially receives a tube for water passage. The support limits radial movement of the tube off the axis. The support has an L-shaped cross section having a radial leg that seats the O-ring, and an axial leg. Water purifiers are often installed in confined spaces near mechanical equipment. Conventional water purifiers installed with sharp bends in influent and effluent water tubes and exposed to equipment vibration conducted by the tubes often exhibit weeping at the port. In an embodiment of the present invention, weeping is eliminated by maintaining axial relation between the tube, the seal, and the collet.
