Abstract:
The high pressure coupling for hoses comprise a nipple structure including a main portion, a connecting nipple portion extending from the main portion in one direction and a nipple portion extending from the main portion in the opposite direction. A sleeve made from tubular stock is be securely connected to the nipple structure by crimping, flanging etc. The nipple portion includes outwardly projecting, rounded-off ribs cooperating with rounded-off grooves in the sleeve so that the hose inserted between the nipple portion and the sleeve is held securely in position after the nipple portion is internally expanded with subsequent reduction of the cylindrical surface of the sleeve. Both the nipple structure and the sleeve are made from appropriate stock machined accurately to the required dimensions. Sharp edges provided in the nipple main portion will anchor themselves securely in the crimped or flanged-over end of the sleeve-like member to assure a secure fastening between these two parts.
