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
Illustration 3 g01288160
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.
Table 1
Ampseal 16 Connector Seals    
Part Number     Description    
264-7029     2 Position Connector Seal    
264-7030     3 Position Connector Seal    
264-7031     4 Position Connector Seal    
264-7032     6 Position Connector Seal    
264-7033     8 Position Connector Seal    
264-7034     12 Position Connector Seal    
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 connectors.

Damaged product should not be used. If a damaged product is evident, it should be replaced with a new one.
Reassemble the TPA to the plug housing using the appropriate steps outlined in ""Reassembly of Connector"".Reassembly of Connector
Reassembly of the plug after servicing a seal should be performed as follows:
Illustration 8 g01288449
Align the keying features of the TPA with the appropriate features in the plug housing. Refer to Illustration 8.Note: Single row plug assemblies are keyed by the location of the plug latching fingers. TPA fingers go on top of the contacts. Dual row plug assemblies have a "V" shaped notch inside the housing keys with a matching "V" shaped rib on the bottom of the TPA.
Illustration 9 g01288448
Push the TPA into the fully locked position. Refer to Illustration 9.
Tug gently on the wires to ensure that the terminals are fully inserted into the connector. The plug assembly is now ready to be connected to the receptacle.
