PRT® is a wrap-around, heat-shrinkable tubing that provides a means of adding additional insulation to an assembled wire or cable. PRT® can be used to protect in-service electrical systems without the need to remove or disassemble the associated connectors and end hardware. This product is also a great in-service repair tubing where a side-entry installation is required.

A heat gun is used to recover the material in a fashion similar to standard, non-split, heat-shrinkable tubing. This material has an operational temperature range of -55° to 135°C (-67° to 275°F).

The best part of the PRT® line of products is that you’ll never again need to remove or disassemble your connectors or end hardware to install or repair.

Simply wrap the PRT® (Clear) over your wire or cable and shrink it. Use a heat gun to recover the material in a fashion similar to standard, non-split, heat shrinkable tubing. This material has an operational temperature range of -55° to 135°C (-67° to 275°F) and is available in 50-foot rolls.

Note: Clarity may vary from translucent to milky white


  • Some other PRT® products are available in six color options and a multitude of diameters with National Stock Numbers (NSN)
  • Use PRT® (Clear) like a clear heat shrink tube that’s been split longitudinally
  • Avoid disassembly while repairing and protecting cables and wires


  • Handles up to 17,500 volts and is resistant to the harshest fluids, including jet fuel, Skydrol, and many others
  • Has excellent abrasion resistance that holds up in harsh environments
  • Pre-split longitudinally, so you never need to remove connectors or end hardware
