Deutsch Sealing Plugs

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 unwired cavity in your assembly.

How To Install A Sealing Plug

1. Holding the sealing plug with the large diameter end away from the connector, gently apply downward pressure to force the sealing plug into the cavity.
2. With perpendicular motion, apply downward pressure to the large diameter end of the sealing plug.
3. Apply pressure until the sealing plug is force to stop by contact with the rear grommet.
4. Visually inspect the sealing plug to confirm it is flush with the cavity opening

Sealing Plugs Vs. Keying Pins

Sealing Plugs: A sealing plug is a component that is used to seal off unused cavities in a connector to prevent the entry of moisture, dirt, or other contaminants. Sealing plugs are often used in connectors that have multiple cavities that are not all in use, such as in automotive or industrial applications.

Keying Pins: A keying pin is a component that is used to ensure that a connector is mated correctly with its corresponding connector. Keying pins are used to prevent the accidental mating of incompatible connectors or to ensure that connectors are properly oriented when they are connected. They typically have a unique shape or pattern that matches the corresponding connector and can only be inserted in a specific orientation.

Benefits of Using Sealing Plugs

Sealing plugs are an important component of Deutsch connectors because they help to prevent moisture, dust, and other contaminants from entering the connector and damaging the electrical contacts inside. These contaminants can cause corrosion, which can lead to poor electrical connections, and ultimately, system failure.

By using sealing plugs, you can help to ensure that your Deutsch connectors remain protected from the elements, even in harsh environments. Sealing plugs are particularly important in applications where the connectors will be exposed to moisture, such as in marine or automotive applications, as well as in outdoor applications where the connectors may be exposed to rain, dust, or other environmental hazards.
