Abstract

A method for providing a hose pipe connection is disclosed. Embodiments of the method start with a pipe having an enlarged end portion. A sleeve is introduced into the end of the flexible hose. The sleeve has an inner diameter that is equal to the inner diameter of the hose. In an embodiment, the inner diameter of the sleeve is increased while the end of the hose is already placed on the sleeve. The hose fitted with the sleeve is then introduced into the enlarged end of the pipe. Crimping of the enlarged end will then secure the sleeve and the hose and provide a fluid tight and mechanically sturdy connection.
