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 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 two halves of the A/C condenser core
couplings. All other couplings have two O-ring seals.
Use only the O-ring seals listed in the Ford Master Parts Catalog for the spring lock coupling.
A plastic indicator ring is used on the spring lock couplings of the A/C evaporator core to
indicate, during vehicle assembly, that the coupling is connected. Once the coupling is
connected, the indicator ring is no longer necessary but will remain captive by the coupling near
the cage opening.
The indicator ring may also be used during repair operations to indicate connection of the
coupling.
An A/C tube lock coupling clip (19E746) may be used to secure the coupling but is not required.
Service Gauge Port Valves
The high-pressure service gauge port valve is located on the A/C manifold and tube.
The low pressure service gauge port valve is located on the suction accumulator.
