O-Ring Replacement

IMPORTANT: Even though O-rings may look identical, it is extremely important that only recommended service replacement air conditioning (A/C) O-rings be used or excessive leakage of refrigerant may occur.

IMPORTANT: Always slip the O-rings onto the flange tube to ensure proper locating and sealing. Install new Daewoo-approved service replacement A/C O-ring whenever a joint or a filling is disassembled, except when the O-ring are provided on new components.

When replacing O-rings on an A/C component or a joint connection, the filling design should be identified to ensure installation of the correct air conditioning service replacement O-rings. Some joint connections and components will implement a "captured" O-rings design fitting that uses a groove to retain the O-rings. Others do not have a groove and use a "non-captured" or "standard" O-rings. Assembly and tightening procedures are the same for both designs, but the O-rings are different.

NOTE: 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.
