发明名称 LIGHTWEIGHT FIRE HOSE COUPLING WITH PROTECTIVE SHOULDER AND METHOD OF MANUFACTURING THE COUPLING
摘要 A fire hose coupling includes a substantially annular body having a first end adapted to connect to a fire hose and a second end having male threads. The annular body has a central bore. The coupling includes circumferentially spaced-apart lugs extending radially outwardly from an outer surface of the first end of the body. The coupling further includes a protective shoulder extending radially outwardly from the body between the male threads and the lugs. The protective shoulder has an outer diameter greater than an outer diameter of the male threads to thereby protect the male threads.
