PRT® (ES-100)
  • Available in six color options and PRT® (ES-135) provides a multitude of diameters with National Stock Numbers (NSN)
  • Never disconnect or pull through another wire or cable again and water block it
  • Excellent-anti abrasive, environmental, chemical, and electrical properties with resistance to most oils and fluids, mild acids, and alkalis

PRT® (ES-100) is our wrap-around, military-grade PRT® heat shrink, combined with our water blocking, hot-melt Z-Block™ (100). PRT® is a flame-retardant, abrasion-resistant, chemical-resistant, and fluid-resistant polyolefin heat shrink. PRT® is also RoHS compliant and UL-rated. PRT® repairs or re-jackets damaged components that cannot be disassembled.

Z-Block™ (100) is a hot-melt adhesive tape that blocks and seals wires from fluids, oils, and greases. Z-Block™ (100) creates an environmental seal that will prevent fluids from damaging or penetrating components. Z-Block™ (100) is also RoHS compliant.

Pairing PRT® with Z-Block™ (100) creates the perfect solution for wires or cables exposed to fluids, and need repair or a durable jacket to prevent damage from occurring. PRT® (ES-100) comes in a standard 50-foot roll that can be cut to any desired length, offering versatility for application. PRT® (ES-100) is engineered for diameters ranging from 0.04” to 0.25”, with custom sizes available upon request. PRT® (ES-100) can also be customized with having a range of color options available for applications that may need color-coding. The operational temperature range is -67°F to 212°F (-55°C to 100°C).

We also offer PRT® (ES-135), which has a higher temperature range of up to 275°F, as well as NSN’s for easy procurement.
