In situations where the harness design requires that not all of the plug or socket cavities are being used, inserting sealing plugs into the empty cavities maintains the weather resistance characteristics of the finished assembly. Sealing Plugs can be used in place of either solid or stamped and formed contacts, and are available in sizes to fit all Deutsch connector series and connection accessories. Sealing plugs will fit in both plug and socket cavities, and you need one for each non wired cavity in your assembly.

This silicone sealing plug fits size 12-16 cavities on all Deutsch connectors.
