Flexible Polyolefin Tubing

When your electrical connections, wires, and components need long-lasting protection, you cannot afford sleeves or materials that fail under pressure. Flexible polyolefin heat-shrink tubing offers reliable insulation, abrasion resistance, and environmental sealing, ensuring your work remains safe, compliant, and performs at the highest level.

With multiple shrink ratios, diameters, and performance ratings available, you can equip your projects with a durable, industry-standard solution that works as hard as you do.

Why Choose Flexible Polyolefin Heat Shrink Tubing?

You need dependable wire insulation that withstands heat, moisture, abrasion, and mechanical stress. Flexible polyolefin heat-shrink tubing delivers all of this and more, offering a high-performance balance of flexibility, durability, and consistent shrink performance.

This tubing is widely used in electrical, industrial, automotive, aerospace, and OEM settings where reliability is non-negotiable.

Material Properties

Your tubing material matters. Flexible polyolefin delivers consistent performance across demanding environments:

• Durable polyolefin construction designed for long-term electrical insulation
• Flame-retardant options (check specific product specs)
• High-temperature tubing is ideal for elevated heat exposure
• Smooth, flexible walls for clean installation even around tight bends
• Excellent chemical resistance for oils, solvents, and moisture
• UL-listed options available across many sizes
• Uniform shrink characteristics for a tight, professional seal
• Thick-wall and thin-wall selections depending on your insulation needs

Common Applications

Whether you are insulating a single wire or building an industrial harness assembly, flexible polyolefin heat-shrink tubing provides the protection your components need.

Use it for:

• Wire insulation and strain relief
• Environmental sealing on cables and connectors
• Color coding and organization across harness assemblies
• Abrasion protection for exposed wires and terminals
• Bundling and identification of wiring groups
• Protection for solder joints and spliced connections
• Industrial heat shrink needs in manufacturing and electronics
• Automotive under-hood wiring exposed to heat and vibration

Technical Specifications

Your job demands accurate, reliable technical data. Flexible polyolefin tubing offers the specs required for commercial, industrial, and specialty applications:

• Available shrink ratios:
  • 2:1 shrink ratio
  • 3:1 shrink ratio
  • Select heavy-wall options in higher ratios depending on diameter
• Temperature ratings:
  • Operating temperature typically from -55°C to +135°C
  • Shrink temperature around 90–120°C
• Tubing sizes offered:
  • Full range from small-gauge electronics to large-diameter cable jackets
• Environmental resistance:
  • UV-resistant options
  • Chemical-resistant performance
  • Moisture-blocking seals when adhesive-lined variants are used
• Certifications:
  • UL, CSA, and military-grade options depend on the specific part number

If you need printed identifiers for harness assembly or branding, you can also explore custom printed polyolefin. Learn more on the Custom Printed Heat Shrink page using keyword-rich anchor text such as custom printed heat shrink tubing for identification.

Product Versatility

You can order flexible polyolefin tubing in:

• Continuous spools
• Pre-cut lengths
• Multipacks and assortments
• Single-diameter bulk quantities
• 3M heat shrinkable flexible polyolefin tubing (select models)

This gives you complete control over how you stock and apply your polyolefin heat shrink, whether you are managing field repairs or high-volume production.

Frequently Asked Questions

You want to make the right choice for your wiring, insulation, and protection needs, and having the correct information helps you move forward with clarity. These FAQs guide you through the details you care about most, so you can select your tubing without second-guessing.

Is flexible polyolefin heat shrink tubing good for outdoor use?

Yes. Many polyolefin tubing types offer UV resistance and environmental sealing, making them a strong choice for outdoor and industrial environments.

What is the difference between 2:1 and 3:1 shrink ratios?

A 2:1 shrink ratio shrinks to half its original diameter. A 3:1 shrink ratio shrinks to one-third, giving you a tighter seal around irregular shapes.

Does this tubing work on high-heat applications?

Yes. Most flexible polyolefin tubing supports continuous operation up to 135°C, making it suitable for elevated temperature conditions.

What’s the best cable tie for outdoor use?

For outdoor environments, you typically want UV-resistant black nylon cable ties for the best long-term durability.

Can I print on polyolefin heat shrink tubing?

Yes. You can add custom text, logos, color marks, or identifiers using the custom printed heat shrink service.
