Ford Spring-Lock Coupling Garter Spring & O-Ring Part Numbers Diagram

This document is an exploded parts illustration showing garter springs and O-rings used in automotive spring-lock (quick-connect) coupling fittings, commonly found in air conditioning refrigerant lines. Three panels are shown: the top panel depicts a coupling fitting with the internal garter spring called out, along with a legend listing replacement garter spring part numbers by fitting size, 3/8 inch (E1ZZ-19E576-A), 1/2 inch (E1ZZ-19E576-B), 5/8 inch (E35Y-19E576-A), and 3/4 inch (E69Z-19E576-A). A footnote indicates that the springs marked with an asterisk (3/8, 1/2, and 5/8 inch) are also available in kit E35Y-19D690-A, which includes O-rings. The middle panel shows the male and female halves of the coupling separated, with the O-rings on the male fitting identified. The bottom panel shows the assembled coupling with the garter spring location highlighted. The illustration reference number is V5908-C. A reader can use this document to identify the correct replacement garter spring part number for each line size and to understand where the garter spring and O-rings are positioned within the spring-lock coupling.
