Abstract
A hose coupling, and method of constructing same, for sealably interconnecting a flexible hose and a rigid center pipe. The hose coupling is assembled without requiring relative rotation between the rigid center pipe and the inner surface of the flexible hose. The method includes the steps of inserting an end of the center pipe rectilinearly into the opening of the flexible hose, disposing a compression sleeve member having first and second outwardly facing frustoconical surfaces about the flexible hose, disposing first and second complementary threaded tubular members, which respectively define first and second outwardly facing frustoconical surfaces, about the flexible hose and rigid center pipe, respectively, and threadably drawing the first and second complementary threaded tubular members together such that the first and second outwardly inwardly facing frustoconical surfaces respectively force the first and second outwardly facing frustoconical surfaces inwardly to compress the compression member tightly about the flexible hose and the center pipe. The hose coupling includes the compression sleeve member, the first and second complementary threaded tubular members, and the co…
