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.
