Abstract
A hose construction, coupling unit and system therefor and methods of making the same are provided, the hose construction comprising a flexible hose having opposed ends, a tubular member having opposed ends one end of which is carried by one of the ends of the hose and other end of which extends outboard of the one end of the hose, and an annular coupling unit rotatably carried on the other end of the tubular member outboard of the one end of the hose, the coupling unit having an externally threaded portion for threadedly connecting with an internally threaded coupling device, the coupling unit having an annular portion provided with a tool gripping external peripheral surface for rotating the coupling unit on the tubular member in order to threadedly interconnect the threaded portion with the coupling device, the annular portion being a part that is separate from the threaded portion so as to be adapted to be rotated relative thereto to tend to prevent unthreading of the threaded portion from the coupling device when the annular portion is being rotated relative to the threaded portion.
