ABSTRACT:
A multi-diameter tube coupling is provided for interconnecting flexible plastic tubing of the type used in drip irrigation systems and the like, wherein the tube coupling is adapted for use with a range of different tubing sizes. The tube coupling includes a central body defining an internal flow path, with a retainer collet mounted thereon at each open end of the flow path to capture a seal member having a compliant, pressure-activated seal lip. The retainer collet includes an annular array of lock fingers for unidirectional slide-fit locked reception of one end of a length of tubing within a range of different sizes, with the seal lip engaging the tubing to provide a substantially leak-proof connection. Alternatively, the collet lock fingers accommodate slide-fit locked reception of a barbed swivel adapter, with the seal lip engaging the adapter to provide a substantially leak-proof connection.
