The tubing, the barbed fitting and the overmolded thermoplastic sleeve are all made of a thermoplastic material and the overmolded thermoplastic sleeve is installed such that such that at least one of a cross-linked chemical bond or a physical mechanical interlocked connection is formed to provide a leak-proof connection.
