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.
