35mm Heat Shrink Tubing — Reliable Wire Insulation & Cable Protection

Exposed wire splices, bare connector terminals, and unprotected cable bundles are a liability — whether you're wiring an automotive harness, marine electrical system, or industrial control panel. This 35mm heat shrink tubing gives electricians, auto technicians, and serious DIYers a clean, professional way to insulate, seal, and protect large-diameter cables and wire bundles in one step.

Each piece is 35mm (≈1-3/8") in inner diameter with a 2:1 shrink ratio, meaning it shrinks down to approximately 17.5mm (≈11/16") when heat is applied. Made from polyolefin, it delivers consistent wall coverage and a snug fit around cables, connectors, and splices. Available in multiple lengths — see variant options above.

Typical use cases include protecting large wire harness splices in automotive and RV builds, bundling and insulating cables in marine electrical installations, and covering exposed terminals on industrial connectors and battery cables — all situations where a secure, heat shrink wire sleeve is essential for long-term reliability.

🔌 Compatible with standard polyolefin heat shrink applications. Fits cables and bundles up to 35mm OD. Shrinks with any standard heat gun. Suitable for automotive, marine, and general electrical use.

✅ Key Features of These 35mm Heat Shrink Tubing Sleeves

  • 🔥2:1 Shrink Ratio — Shrinks from 35mm down to approximately 17.5mm (≈11/16"), conforming tightly around cables, connectors, and wire bundles for a secure, gap-free fit.
  • ⚡Electrical Insulation — Polyolefin construction provides reliable dielectric protection, generally rated for low- to medium-voltage applications up to 600V — ideal for heat shrink wire insulation on exposed splices and terminals.
  • 💧Moisture & Abrasion Resistance — Resists moisture ingress and surface abrasion, helping protect cable bundles in engine bays, under-dash wiring, and outdoor electrical runs.
  • 🌡️Wide Operating Temperature — Typically rated for continuous use up to 125°C (257°F), making it suitable for heat shrink tubing for automotive wiring and other high-temperature environments.
  • ✂️Easy to Cut & Position — Cuts cleanly with standard scissors or a utility knife before shrinking, so you can size each piece precisely for connectors, splices, or cable entry points.
  • 📦Large-Diameter Coverage — At 35mm ID, this tubing handles larger cable bundles and connectors that standard small-bore sleeving cannot accommodate — a practical solution for battery cables, large harness wraps, and industrial cable sleeving.

❓ Frequently Asked Questions

How do I choose the right length of heat shrink tubing?

Measure the section of wire or cable you need to cover and add at least 10–15mm (about 1/2") of overlap on each end. For 35mm diameter tubing, a length of 50mm (≈2") is typically sufficient for most connector and splice applications. Longer runs are available for continuous cable protection — see the variant options above.

What does 2:1 shrink ratio mean?

A 2:1 shrink ratio means the tubing will shrink to approximately half its original diameter when heat is applied. So this 35mm tubing will shrink down to roughly 17.5mm (≈11/16"), conforming tightly around the cable or connector for a secure, insulated finish.

How strong is the insulation provided by this heat shrink tubing?

Polyolefin heat shrink tubing generally provides a dielectric strength suitable for low- to medium-voltage applications, typically up to 600V. It also generally withstands continuous operating temperatures up to 125°C (257°F). Always verify your specific application requirements and contact us if you need certified data.

Can this heat shrink tubing be used outdoors or in marine environments?

Standard polyolefin heat shrink tubing is generally resistant to moisture, UV exposure, and mild chemicals, making it suitable for many outdoor and under-hood applications. For harsh marine or direct-burial environments where a fully waterproof seal is required, a dual-wall adhesive-lined heat shrink variant is typically recommended.

What tool do I use to shrink the tubing?

A heat gun is the most reliable tool — apply heat evenly by moving the gun along the length of the tubing rather than holding it in one spot. In a pinch, a lighter can work for small sections, but a heat gun gives more consistent results and reduces the risk of scorching or uneven shrinkage.

What wire or cable sizes does 35mm heat shrink tubing fit?

35mm (≈1-3/8") inner diameter tubing is designed for larger cables, wire bundles, and connectors. It typically fits cable bundles or individual cables with an outer diameter up to approximately 35mm before shrinking. After shrinking, it conforms to cables as small as roughly 17–18mm in diameter, making it a versatile choice for large harness wraps and battery cable insulation.

Is this tubing RoHS compliant and safe for electrical use?

Most standard polyolefin heat shrink tubing is manufactured to be RoHS compliant and free of hazardous substances. If compliance documentation is required for your project or application, please contact us to confirm the specific certification status for this SKU before ordering.
