ABSTRACT:
This disclosure deals with a fitting designed to be secured to an end of a flexible hose of the type including an inner tube surrounded by a wire reinforcement. The fitting includes a nipple, a sleeve and a socket. The nipple has a tubular part which is inserted into the end of the inner tube. The sleeve includes an insert part that is positioned between the end of the inner tube and the wire, and the socket is located around the tubular part of the nipple and around the sleeve. The socket is attached to the nipple, and the end of the wire reinforcement is clamped between the socket and the outer surface of the sleeve. The end of the inner tube is located in a pocket formed between the nipple and the insert part. During assembly of the fitting, the socket causes deformation of the insert part of the sleeve and initial compression on the end of the inner tube which is in the pocket. This initial compression combined with barbs formed on the insert, serve to secure the end of the tube in the pocket. Fluid pressure internally of the hose serves to activate a gland seal formed by the end of the tube in the pocket. Tapered surfaces of the socket and the insert part cooperate to deform the insert part in an advantageous manner.
