Abstract: A quick connect-disconnect fluid coupling assembly having cylindrical outer and inner coupling members, one of which is connected to a conduit and the other to a fluid conveying system. The assembly is accomplished by inserting a U-shaped locking member having a bight and two parallel legs into the outer member, which has a peripheral groove receiving the bight so that the curved portion thereof does not extend beyond the periphery. Slots in this member receive the legs, which are then locked around grooves in the inner member and the ends of the legs do not extend beyond the periphery of the outer member. The outer portion of the bight is thinner than the inner portion to permit easy insertion into, and withdrawal from, the groove of the outer member. The system may also be utilized in an assembly of three or more components, wherein two or more locking members are used.

Abstract: An apparatus and method for producing an hydraulic hose having ends of different internal diameters. An uncured hose is produced by conventional extrusion.
