A hose coupling, ferrule therefor and methods of making the same are provided, the method of making the hose coupling (30, 30A) comprising a ferrule (31, 31A) having opposed ends (33, 34) and an insert (32, 32A) interconnected to one of the ends of the ferrule (31, 31A) so that an end (48) of a hose (49) can be inserted into the other end of the ferrule (31, 31A) and over the insert (32, 32A) to be subsequently clamped between the ferrule and the insert, the method comprising the steps of forming the ferrule (31, 31A) from a length of tubular stock (54, 54A) that has opposed ends by rotating the stock, inwardly swedging the stock (54, 54A) at a predetermined location (37, 37A) thereon to define the one end of the ferrule (31, 31A) while the stock is rotating and then cutting off a portion (66, 66A) of the stock (54, 54A) at a desired location thereon that is spaced inwardly from that one end (55, 55A) of the stock (54, 54A) to form the ferrule (31, 31A). |
