ISSUE:
New refrigerant 0-rings (GREEN COLOR) are available for use in the Ford Spring Lock Coupling (SLC) and threaded (Tube-0) connections.
The new GREEN COLORED 0-ring material provides improved sealing and longer seal life. Use of any other 0-ring for Ford refrigerant
fittings is not recommended and may result in premature leakage at the fitting.
ACTION:
If a refrigerant system repair is made which requires an A/C fitting to be disconnected, replace the existing 0-rings with the new GREEN
COLORED type. Refer to the following 0-ring Usage Chart for identifying the correct 0-ring.
