Abstract
A hose coupling subassembly comprising a nipple with an enlarged head at one end, an external thread for attaching a socket to the nipple, and a groove between the head and thread. The subassembly includes a nut with an inturned flange engageable with the head for clamping the head against a part to which the hose coupling is to be attached. The bore of the nut flange is greater in diameter than the thread so that the nut may be assembled to the nipple by sliding it over the threaded portion. The nut is retained on the nipple by a washer extending into the groove.
