Abstract
A hose assembly is formed with a flexible helical hose body, a termination ring secured to an end, and over-molded plastic. The termination ring includes a main ring, a secondary ring, and connector members, each configured to span between and be integrally connected with the main and secondary rings. The main ring has an inside surface formed to threadably couple to a corresponding helical portion of the hose body, and be positioned at least two to three turns away from the hose end. The length of the connector members positions the secondary ring at least two turns closer to the hose end. Each connector member has outwardly protruding ridges. Plastic is over-molded to encapsulate the first end of the hose body, to encapsulate the secondary ring and each connector member, and to encapsulate a portion of the main ring, while extending beyond the hose end to form a soft cuff.
