A/C Spring Lock Coupling: Notes

The spring lock coupling is a refrigerant line coupling held together by a garter spring inside a circular cage. When the coupling is connected together, the flared end of the female fitting slips behind the garter spring inside the male fitting cage. The garter spring and cage then prevent the flared end of the female fitting from pulling out of the cage.
