A thin walled tube having an internal rib

摘要

A thin walled tube (10) is disclosed having a wall (12) which extends between first (14) and second ends (16). The wall (12) has a thickness (t) of less than about .03 inches. The tube (10) also has a longitudinal extending rib (22) formed on an inner periphery (18) thereof. The rib (22) enables the thin tube (10) to be injection molded from a thermoplastic material using standard temperature ranges and relatively short cycle times.
