Abstract: A fitting for connection to an end of a tubular member (204, 304), such as a hose or pipe, the fitting comprising a collar (202, 302) which is received over an outer surface of an end of the tubular member (204, 304), and a separate externally threaded sleeve (208, 308) which has an outside diameter which is larger than an internal diameter of the tubular member (204, 304), and is screwed into the tubular member (202, 304) to expand the tubular member and trap it between the collar (202, 302) and sleeve (208, 308).

Abstract: A field attachable and reusable hose end fitting for convoluted hose. The fitting includes a collar having threads thereon threadable to a convoluted hose end. The same collar has a smooth bore portion encircling the terminal end of the corrugated hose when the collar is threaded thereon. When the nipple of the fitting is inserted into the hose end and the socket of the fitting is threaded to the nipple, the corrugations of the hose are crushed between the inner smooth bore of the collar and the outer surface of the nipple forming a fluid tight seal.
