Abstract
A coupling for coupling a corrugated hose to a socket having a cylindrical body with a 'U'-shaped annular recess therein. The hose has an outside surface with parallel grooves therein. The parallel grooves have slanted or tapered sides. Flexible 'O'-rings are stretched over the outside surface and placed in the parallel grooves near one end of the hose. The hose with the 'O'-rings thereon is pushed into the socket so that the 'O'-rings contact the 'U'-shaped recess. Each 'O' ring provides a seal between each of the tapered sides of the groove in which it is positioned and the 'U'-shaped annular recess to provide a three point contact air seal between the hose and the socket.
