3M™ Cold Shrink Connector Insulators 8420 and 8430 Series are designed using 3M’s proprietary cold shrink delivery system. Products are supplied prestretched on a removable core for efficiency and ease of installation. Removal of the core (unwinding) after positioning the splice allows the product to shrink into position forming a moisture-tight seal. The live memory action of the specially formulated EPDM material promotes a permanent, durable environmental seal and insulation, with a typical operating tem

  1. What is 3M™ Cold Shrink Insulator 8429-6, 10/case used for?

    The 3M™ Cold Shrink Insulator 8429-6, 10/case is used to insulate and seal connections such as coaxial cables and connectors in cellular communication towers, broadcasting antennas and more.

  2. Is the installation of this product easy?

    Yes! One of the advantages of the cold shrink technology is that it simplifies installation by eliminating most steps associated with traditional heat-shrinking methods. Just position it over the connection area before you pull out removal tabs on each end to expand insulators around mating surfaces.

  3. Can I use it outdoors without worrying about water penetration or corrosion?

    Yes! This product has excellent weather resistance properties (UV rays, ozone) along with a very good moisture seal capability protecting copper tubing against environmental elements on-site damages. It also demonstrates high mechanical stability that allows engineers/designers/users reliable performance throughout different types of harsh environments.
