Patent ID: 8091928

Claim:
A coupling assembly comprising: a fitting including a wall presenting an inner surface, surrounding a lumen and an outer surface opposing said inner surface; a barb extending radially away from said outer surface of said wall to a peak; a seal circumferentially surrounding said outer surface of said wall and spaced from said peak of said barb; a hose including a contact layer, a backing layer, a reinforcing layer, and a sheath; wherein said contact layer presents an interior surface surrounding a hollow interior and said sheath surrounds said contact layer and presents an exterior surface opposing said interior surface and presenting an initial outer diameter; wherein said backing layer surrounds said contact layer, said reinforcement layer surrounds said backing layer, and said sheath surrounds said reinforcement layer; wherein said wall of said fitting is disposed in said hollow interior of said hose such that said contact layer of said hose extends over each of said seal and said barb such that said hose is deformed at said barb to present a displaced outer diameter proximate said peak of said barb that is greater than said initial outer diameter of said hose; wherein said barb is not embedded into said contact layer of said hose; a cage spaced at least a distance from said peak of said barb and radially compressing each of said exterior surface of said hose and said seal such that said hose is compressed to present a constricted outer diameter at said cage that is less than said initial outer diameter and said displaced outer diameter to form an interference fit between each of said hose, said barb, and said cage; wherein said seal is in sealing engagement with said interior surface of said hose to prevent leakage of fluid from said coupling assembly.
