Spring Lock Coupling

Fig 1: Identifying Spring Lock Coupling Components

When disconnecting or connecting spring lock couplings, observe the following:

• When the coupling is connected together, the flared end of the female fitting slips behind the garter spring inside the cage of the male fitting.
• The garter spring and cage then prevent the flared end of the female fitting from pulling out of the cage.
• Three O-ring seals are used to seal between the thermostatic expansion valve outlet tube and the compressor inlet tube. All other couplings have 2 O-ring seals.
• Use only the O-ring seals listed in the Ford Master Parts Catalog for the spring lock coupling.
• An A/C tube lock coupling clip is used to secure the coupling.
