Deutsch connectors on AWG 16, 18 or 20 wire need a proper crimp, not a squeeze from a generic pliers. This die is cut specifically for Deutsch terminals and drops into your TH-2000 body in a couple of seconds. You get the right jaw geometry for each gauge, so the contact seat is clean and the pull-test holds. Whether you're wiring a control panel or a vehicle harness, this is the die that keeps you from pulling connectors apart and starting over. Add to cart and it's on your bench for the next job
