Shrinkflex 2:1 Kynar® Heat Shrink Tubing
High-Temperature Protection for Connectors and Splices

What's special about this heat shrinkable tubing?
- High-grade polyvinylidene fluoride (PVDF) material provides cables, splices, and connectors with excellent protection from abrasion, cut-through, fluids, and high temperatures
- Shrinks and matches the contours of uneven connectors to provide an encapsulating effect that helps keep out moisture while preventing the device from cutting-through the material
- Meets MIL-DTL-23053/8 specification to ensure material is safe and reliable for use in military applications requiring heat shrink tubing protection

When it comes to protecting exposed wires and connectors from outside elements, there are many suitable options available, such as electrical tape and polyolefin heat shrink. These products are great for applications requiring minor protection or a cosmetic touch-up, but will ultimately fail under extreme conditions. Kynar® 2 to 1 Heat Shrink Tubing is a semi-rigid material with excellent abrasion, chemical, flammability, cut through, and high temperature resistance properties, which makes it ideal for some of the worst environmental, military, or industrial applications.

- Semi-rigid construction provides strain protection for soldered wires and splices
- Highly flame-retardant Kynar® material withstands high temperatures while providing resistance to solvents, fluids, and chemicals - perfect for use in grueling mechanical applications
- Available in either clear or black colors to accommodate a wide range of job applications, whether it be to hide spliced wiring, or to allow connectors to remain visible for future inspection
- 2:1 shrink ratio allows for easy installation over uneven surfaces
- Cuts cleanly and easily with just scissors, saving on labor and installation
- High shrink temperature of 175°C ensures that tubing will not prematurely shrink during installation in hot environments
- Continuous operating temperature of -67°F to 347°F for extreme environmental conditions
- UL 224 VW-1 flammability rating
