ABSTRACT:
This disclosure relates to a quick connect coupling including a tubular socket or receptacle part having an internal groove formed therein, a tubular nipple or insert part having an external groove formed thereon, and a snap ring. The nipple is insertable into the socket and when so inserted the two grooves are radially aligned. The snap ring is mounted in and extends between the two grooves to lock the socket and the nipple in assembled relation. Prior to final assembly, the snap ring is positioned in the socket groove, and in the space within the socket groove and around the snap ring is applied a relatively viscous fluid. This fluid, which may be a grease, holds the snap ring in the desired position in the groove prior to and during assembly, and it also serves as a lubricant on the ring which facilitates the assembly of the parts.
The disclosure also describes the method of assembly of the coupling.
