Insulation-Piercing Testing

Non-invasive testing in live enviroments where saftey is of paramount concern. No more need to strip or cut wire to be tested, just simple grab the wire you want to test and pierce it with the insulation needle or needles on the contact tip. With needle removal, there is only a small incesion left behind to maintain wire integrity for long-lasting use. Many of our insulation-piercing connectors are sold on already assembled test leads often featuered in many of our kit sections or custom ordered with the exact wire material, guage, length, color, and connector combinations to fit specific testing requirements. To determine which insulation-piercing testing solution is the best fit for you, select one of the following 8 connectors that would fit your testing enviroment, and if the connector is made for attachment to a test lead, look at some of our featuered test leads in parenthesis below. Contact the manufactering plant for specific needs and if we do not have the product already made with your specific test lead combinations, we speacialize in custom assembly.
