3M Cold Shrink Connector Insulators 8420 and 8430 Series are EPDM tubes designed using a unique Cold Shrink delivery system. Products are supplied pre-stretched on a removable core for efficiency and easy of installation. Removal of the core (unwind) after positioning allows the tube to shrink into position forming a moisture-tight seal. The live memory action of the specially formulated material ensures a permanent, durable environmental seal and insulation.

  • Specially designed for primary insulation of solid dielectric insulated wires and cable splicing rated to 1000 volts
  • Simple installation which requires no tools
  • Sealing of terminal lug barrels, conduit couplings and conduit-to-cable breakouts
  • Made of EPDM rubber which contains no chlorides or sulfur
  • Covers a wide range of cable cross sections
  • Withstands temperatures of -40 to 90 degC (-40 to 194 degF)

PRODUCT FAQ

  1. What makes the 3M™ Cold Shrink Insulator 8427-6 different from other insulators?

    The 3M™ Cold Shrink Insulator 8427-6 has a unique cold shrink design that allows for easy installation without the use of special tools or heat. It also provides reliable protection against moisture, weathering, and corrosion.

  2. How many insulation tubes come in one case of the 3M™ Cold Shrink Insulator 8427-6?

    Each case of the 3M™ Cold Shrink Insulator includes ten insulation tubes.

  3. Can I use this insulator on outdoor applications?

    Yes, definitely! The 3M™ Cold Shrink Insulator provides reliable performance outdoors against harsh elements such as UV radiation, moisture, salt spray and extreme temperatures.

  4. Is it hard to install this insulator by myself?

    Not at all! In fact, one advantage of using our product is its simple usage. Unlike conventional slip-on sleeves or heat-shrinks requiring expensive equipment & trained labor force - our flexible tubing easily stretches over cable ends and connector interfaces providing an efficient way to protect your connections with a no-fuss application process.
