PRT® (Clear)



A clear, military-grade, wrap-around heat shrink ideal for applications that need a durable repair and the ability to see through to the wire labels.
  • Abrasion-resistant, fluid-resistant, and fungus-resistant polyolefin
  • Offers superior component repair or a secondary insulation jacket
  • Wrap-around heat shrink allows for installation without disconnection or disassembly

PRT® (Clear) offers the ease of a wrap-around solution with the durability of military-grade polyolefin.

PRT® (Clear) is a clear, wrap-around heat shrink ideal for repairs and adding secondary insulation to wires or cables. The polyolefin heat shrink has a 2:1 shrink ratio, and meets specification SAE-AMS-DTL-23053/5, as well as being abrasion resistant and fungus resistant. Additionally, PRT® (Clear) is resistant to the harshest fluids, including jet fuel and Skydrol. The adhesive is a clear acrylic-based transfer adhesive with a high-bond strength. The adhesive is equipped with a paper release liner for quick and clean installation.

If your application calls for different lengths, PRT® (Clear) can be easily cut for versatility in uses. Because of the wrap-around construction, installing PRT® (Clear) can be done without needing to disconnect or re-wire components. Simply wrap PRT® (Clear) around the damaged area of the wire, or where additional insulation is desired, and heat evenly with a standard heat gun.

PRT® (Clear) is offered in 13 diameter ranges, for wires as small as 0.25” to as large as 1.87”, with custom sizes available upon request. The operational temperature range is -67°F to 275°F (-55°C to 135°C).


  • Clear heat shrink allows for visibility of wire label
  • Resistant to abrasion, fungus, and fluids such as jet fuel and Skydrol
  • No re-wiring needing; just wrap around wire and heat evenly


  • Can be cut to desired length
  • Paper release liner provides a cleaner installation process
  • Operational temperature range is -67°F to 275°F (-55°C to 135°C)
