EESeal® EMI Filter Installation For DSub Connectors
The design and construction of EESeal® FilterSeals makes them easy to install by hand, without special tools, but care is needed to ensure proper insertion. Most EESeals are equally easy to extract; view extraction instructions.

Step 1: Which side is UP?
If your EESeal® has a blank side with no printing on it, the blank side is up and visible once the EESeal® is inserted.If both sides of your EESeal® have printing on them, then the side with the EESeal® logo is facing up and is visible after the EESeal is inserted.
Important Note: It is imperative that the EESeal® be inserted “right side up”. Failure to do so will prevent the EESeal® from working as it’s intended to, and may cause functional problems.
Step 2: Orient the EESeal®
With the correct side up, orient the EESeal® so its pinholes roughly correspond to the corresponding pins in the host connector. Most EESeals® have at least pin 1 (or pin A) marked to assist you in this orientation.
Important Note: It is imperative that the EESeal® be inserted so its pinholes are aligned with the matching pins in the connector – pin A to pin A, or pin 1 to pin 1, and so on. Your EESeal® may have a different treatment for each pin, and proper orientation will ensure each pin gets the correct circuit connection.
Step 3: PARTIALLY Insert the EESeal®
Slightly cup the EESeal® so that Pin 1 (or pin A) can be easily slipped onto the corresponding pin in the host connector. Double-check that the correct EESeal®pinholes are going over the correct pins in the connector. Gently use your fingertip to push the EESeal® down just over the head of the pin, no further. Now simply press the rest of the pinheads into the EESeal® pinholes in the same manner. To make the EESeal® go on easily, notice that the EESeal® is intentionally oversized, so your pressing action should be towards (not away from) the pins already completed. Do not attempt to push the EESeal® down any further than just over the heads of the pins.
Match the D shape of the EESeal to the D shape of the connector.
Partially insert just the tip of the pins into the pinholes.
Step 4: Fully Insert & Seat the EESeal®
First, confirm that you can see the tip of each and every pin slightly poking through its corresponding EESeal® pinhole (if not, complete step 3 before proceeding). The EESeal® can be fully inserted and permanently seated by simply mating the connector pair. Now check the EESeal® to ensure it is flat at the bottom of the connector, with no folds along its edge or interior. It should appear like it belongs there. If you notice anything unusual, please contact us.
Seat the EESeal so that all of the pins are fully exposed.
