Heat shrink tubing is an excellent, cost-effective material ideal for bundling, harnessing and/or providing environmental protection for cables and hoses. When it comes to extreme protection, not all heat shrinks are made the same, and many will eventually crack, blister, or completely fail when introduced to corrosive elements, high temperatures, and solvents. 2/1 Viton® Heatshrink Tubing is specifically designed to withstand grueling temperatures while remaining resistant to a wide range of fluids, fuels, solvents, and other corrosive materials. This highly flexible, rubber-like heatshrink is excellent for hard working applications, whether it be providing environmental protection for cables and hoses on construction equipment, or keeping electrical wiring in engine compartments safe from fuel and oil.

  • Flame retardant material stands up to grueling temperatures while providing longevity in some of the worst environments
  • Resistant to highly corrosive acids, fluids, fuels and solvents for use in oil rigs, heavy machinery, or military applications
  • High operating temperature of 392° F for reliable use in extreme environmental applications
  • Flexible, rubber-like quality provides maximum protection, without restricting the natural movement and bend radius of cables or hoses
  • Cuts cleanly and easily with just scissors, saving on labor and installation
  • High shrink temperature of 248° F ensures that tubing will not prematurely shrink during installation in hot environments
