Cut the end of the cable off square with a set of wire cutters. Place the coax in a stripper tool, with the end flush against the side of the tool. Twirl the strip tool 360 degrees in both directions around the cable until the crunching stops. (5 to 10 turns.)
Remove the strip tool and pull off the stripped material. Fold back the remaining braid so that there is only one layer of foil left against the center white dielectric. Note that with quad shield cable, there may be two layers of braid and one layer of foil to remove. When using our stripper, adjust the blade so that it cuts through the outer layer of braid and foil. This makes the crimping operation much quicker and easier. If you do not get everything except the innermost layer of foil removed, it may be very difficult to push on the connector.
Insert the cable into the Perma Seal or other Compression style connector. When inserted properly, the white insulator of the cable should be flush with the metal flange, you can see this action by looking into the connector at the threaded end. If you cannot get the coax to go in all the way, pull it out and push it in again. Sometimes the cable catches on the inner ring or the braid catches. If the cable jacket is loose, you may need to kink the cable slightly in your palm while pressing it into the connector (no more than 45 degrees).
Lay the cable-connector assembly into the crimp tool. Squeeze the handle until the top ring seats all the way into the connector. You should hear or feel a "click" as it pops into position. Remove the coax and connector from the crimper.
Test the crimp by giving the cable a nice tug, all should be fine. If not the tool may need some minor adjustments or the braid may have prevented the connector from seating properly. FYI, YOU CANNOT REUSE THE CONNECTOR. You will need to try another if the cable pulls out.
