All you need is your thumb and 30 seconds to install an EESeal® FilterSeal EMI Filter insert into your connector. The video below shows an actual installation of a D-Sub 25 into a SCSI connector (Video Notes)

EESeal® EMI Filter Insertion

for Circular and DSubminiature Connectors only - see links below for other connector styles

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.

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 1 to pin 1, or pin A to pin A, 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.
Step 4 Fully Insert & Seat the EESeal.
First, confirm that you can see the head 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.

EESeal® EMI Filter Insert Extraction

The EESeal® EMI Filter inserts are designed to be permanently installed in a your connector and, once seated, will not come out unless intentionally extracted. The EESeal can be extracted without damage using a special extraction tape we can provide upon request. MDM-style EESeals cannot be extracted without damaging the EESeal.
