Heat Sleeves Insulation

High Temperature Wire Sleeve – Safeguarding Vital Circuits

Electrical looms near exhausts, turbochargers, or hydraulic lines demand a purpose-built high temperature wire sleeve. We manufacture sleeves from premium substrates (fibreglass, basalt, and silicone-coated variants) that maintain dielectric strength while resisting continuous heat. Each high temperature wire sleeve is flexible for tight routing, cuttable for field installs, and tough enough for heavy-duty environments.

Choosing the right high temperature wire sleeve is simple: match the diameter to your loom, allow clearance for connectors, and pick the coating that best suits your exposure (oil, chemicals, dust). With the correct specification, a high temperature wire sleeve can dramatically reduce heat-related faults and unplanned downtime.

Thermal Pipe Sleeves – Keeping Flow Stable

Thermal pipe sleeves help moderate surface temperatures on coolant and fluid lines, improving comfort and component longevity around hot zones. In mixed harness areas, pair a pipe sleeve with a heat proof cable sleeve to protect adjacent electrical runs and sensor lines from radiant and conductive heat.

Heat Shield Insulation Sleeves – Robust Barrier Protection

When radiant heat is the problem, our layered heat shield sleeves form a high-reflectivity barrier that keeps temperatures in check. Combine a shielded hose cover with a heat proof cable sleeve for nearby wiring to create a complete thermal strategy. The result is cooler components, more consistent performance, and easier maintenance access.

Why Heat Insulation Matters

• Extends the lifespan of appliances, vehicles, and machinery by controlling thermal stress.
• Improves efficiency by limiting heat soak into intakes, sensors, and electronics.
• Enhances safety by reducing burn risk and insulating high-temperature touch points.
• Reduces fault rates in cable looms when protected with a heat proof cable sleeve.

Installing Thermal Sleeves – Quick Guide

1. Measure the outside diameter of the loom, hose, or pipe—including connector wings—to size your sleeve correctly.
2. Cut to length; deburr edges. Slide on, or wrap if using a self-closing design.
3. Secure ends with stainless ties or heat-rated clamps. For branched looms, stagger and overlap for continuous coverage.
4. Where wires run near exhausts, add a high temperature wire sleeve over the section most exposed to heat.
5. For mixed harnesses, protect conductors with a heat proof cable sleeve and shield nearby pipes with reflective covers.

Frequently Asked Questions

1) What makes a high temperature wire sleeve different from standard loom tubing?

A high temperature wire sleeve is built from heat-resistant fibres and coatings that maintain integrity at sustained elevated temperatures. Unlike standard PVC or split conduit, it resists radiant and conductive heat, oil splash, and vibration while remaining flexible.

2) When should I choose a heat proof cable sleeve instead of tape or wrap?

Use a heat proof cable sleeve when you want continuous protection along a run, quick removal during maintenance, and repeatable fit. Tape and wraps are great for irregular shapes, but a heat proof cable sleeve offers faster installs and cleaner rework on service cycles.

3) Can I use both a high temperature wire sleeve and a heat proof cable sleeve on the same loom?

Yes. Many technicians layer a high temperature wire sleeve as the primary insulator and add a reflective heat proof cable sleeve on the outside for extra radiant protection near exhausts and turbo housings.

4) What temperature ratings should I look for?

For under-bonnet zones, aim for continuous ratings in the 250–550°C class depending on proximity to manifolds or turbos. A correctly specified high temperature wire sleeve or heat proof cable sleeve will list both continuous and peak tolerances.

5) Will sleeves affect cable flexibility or serviceability?

Quality sleeves maintain bend radius and are easy to remove and refit. A self-closing heat proof cable sleeve is ideal where frequent inspection is required; fixed high temperature wire sleeve constructions suit permanent protection.

6) Are these sleeves suitable for industrial and off-road environments?

Absolutely. Our high temperature wire sleeve range and exterior heat proof cable sleeve options are abrasion-resistant and compatible with oils, coolants, and common workshop chemicals.

7) How do I size a high temperature wire sleeve correctly?

Measure the thickest section of the loom including connectors. Choose a high temperature wire sleeve with enough clearance for easy routing but tight enough to avoid sagging. For multiple branches, consider a self-closing heat proof cable sleeve.

8) Can sleeves reduce electrical faults caused by heat?

Yes. Persistent heat accelerates insulation breakdown. Using a high temperature wire sleeve on hot-zone runs and a reflective heat proof cable sleeve near radiant sources helps stabilise cable temperatures and prolongs insulation life.

9) Do I need special tools to install these sleeves?

No special tools are required. A sharp cutter and stainless ties are usually enough. For best results, terminate a high temperature wire sleeve with heat-rated clamps and finish a heat proof cable sleeve with edge sealing where fluids are present.

10) Where can I purchase Kool Wrap sleeves?
