A/C Coupler O-ring: Service Precautions
IMPORTANT: Even though O-rings may look identical, it is extremely important that only recommended service replacement air conditioning O-rings
be used, or excessive leakage of refrigerant may occur.
IMPORTANT: Always slip the O-ring onto the flange tube to ensure proper locating and sealing.
Install new Daewoo-approved service replacement air conditioning O-rings whenever a joint or a fitting is disassembled, except when the O-rings are
provided on new components.
When replacing O-rings on an air conditioning component or a joint connection, the fitting design should be identified to ensure installation of the
correct air conditioning service replacement O-ring. Some joint connections and components will implement a "captured" O-ring design fitting that uses
a groove to retain the O-ring. Others do not have a groove and use a "non-captured" or "standard" O-ring. Assembly and tightening procedures are the
same for both designs, but the O-rings are different.
Before installation, verify that both O-rings and fittings have not been nicked or deformed. Deformed or nicked parts must be replaced. Failure to use the
proper service replacement parts and procedures may result in excessive refrigerant leakage.
