This Special Instruction describes the procedure that is required to service the peripheral seals of the Ampseal 16 Connector System.Note: Do not perform any procedure in this Special Instruction until the information has been read and understood.
Use all cleaning solutions with care and in a well ventilated area. Always wear eye protection when using cleaning solutions. Failure to follow the precautions provided by the manufacturer on using, storing and disposing of any cleaning solution can result in bodily injury.
Peripheral Seal Servicing
Conditions in the field may require that the peripheral seal of the Ampseal 16 plug assembly be serviced. Servicing the connector involves cleaning and lubrication, or replacing the seal when the connector is opened. The following contaminants may require that the seal be serviced.
Excessive exposure to diesel fuel
Dust
Other contaminantsClean seals that are dirty. Replace seals that are torn or swollen. Refer to Illustration 1 for an example of seal conditions.

Description of Seals for the 12 Pin Connector (1) 1 Hour Unmated (2) Unexposed (3) 48 Hours mated When Ampseal 16 connectors have been exposed to excessive dust, remating of the serviced connector may be difficult. Clean connectors that have been unmated for service purposes before reconnecting.

Many solvents have been found to damage some connector materials. Solvent based cleaners are not recommended. It is important that the connector mating surfaces be clean and dry before remating. If dirt or corrosion cannot be removed from the mating surfaces, the connector and/or terminals must be replaced.
Clean the interior mating surfaces. Use a cotton swab and denatured alcohol to clean the surfaces. Refer to Illustration 2. The interior mating surfaces are the following components:
Terminals
Seals
Insulators

Ensure that the surfaces of the connector are dry. Coat a cotton swab with 129-1968 Multipurpose Grease and apply the grease to the surface of the peripheral seal. Applying grease to the connector will allow the connector to mate with decreased resistance. Refer to Illustration 3.Replacement of the Peripheral Seal
Replace the peripheral seal if the seal is torn or the seal is swollen. Table 1 contains a list of peripheral seal part numbers available for the Ampseal 16 connector.

Ensure that the new seals are kept away from the cleaning solution. Exposure to the cleaning solution will remove the oils contained in the seal and could increase the force required to mate the
