FEP Heat Shrink Tubing

With a range of shrink ratios, our FEP heat shrink tubing ensures a tight, secure fit around wires, cables, and components.

It is available in various lengths, IDs (inner diameter) and wall thicknesses to meet specific project requirements.

  • ID Before Shrink: 3.0mm - 12.0mm
  • ID After Shrink: 2.3mm - 7.5mm
  • Wall Thickness: 0.03mm - 0.35mm
  • Length: 0.5m - 2.0m
  • Shrink Ratio: 1.3:1, 1.6:1, 2:1

By Heat Shrink Ratios

1.3 to 1 FEP Heat Shrink Tubing

1.3:1 Shrink Ratio

  • Shrinks to approximately 77% of its original diameter.
  • When minimal shrinkage is required, ensuring a closer fit with less stress on the underlying material.
  • Provides a snug fit without excessive compression.
1.6 to 1 FEP Heat Shrink Tubing

1.6:1 Shrink Ratio

  • Shrinks to about 63% of its original diameter.
  • Offers more shrinkage than 1.3:1 but still avoids excessive force on delicate components.
  • Provides more coverage while maintaining clarity and chemical resistance.
2 to 1 FEP Heat Shrink Tubing

2:1 Shrink Ratio

  • Shrinks to about 50% of its original diameter.
  • When a significant reduction in diameter is needed to fit over larger components before shrinking.
  • Allows for more flexibility in fitting over irregular shapes and larger connectors.
