Product Information

Full details

The COOL IT Thermo-Tec Heat Sleeves are designed for automotive and industrial applications to protect vital wires, cables, and hoses from extreme heat, accidental liquid spills, and brief flame exposure. Their key benefit is robust protection in high-temperature environments, offering a significant safeguard against damage and failure. A potential consideration is that they are supplied in fixed 3-foot lengths. These sleeves are constructed from a durable braided fiberglass material coated with a silicone rubber compound, providing continuous heat resistance up to 250°C and short-term tolerance up to 1200°C.

FAQs

What is the continuous operating temperature limit for these heat sleeves?

The COOL IT Thermo-Tec Heat Sleeves can handle continuous heat protection up to 250°C (482°F).

Can these sleeves protect against liquid spills?

Yes, the silicone rubber coating provides protection against liquid spills and splashes.

What are the available sizes for these heat sleeves?

They are available in a range of diameters. This guide focuses on the 1/2 inch diameter model, but other sizes like 3/4 inch are also offered.

How are the heat sleeves supplied?

The Heat Sleeves are supplied in standard 3-foot lengths.

Can I use these sleeves for wiring that is constantly exposed to flame?

The sleeves are designed for occasional exposure to flame and offer short-term protection up to 1200°C. They are not intended for continuous direct flame impingement.

What material are the heat sleeves made from?

They are constructed from a high-quality braided fiberglass sleeving coated with a silicone rubber compound.

How do I install the heat sleeve if I cannot slide it over the component?

You can carefully slit the sleeve lengthwise with a sharp knife or scissors and then wrap it around the component. Secure the edges using high-temperature tape or appropriate clamps.

Troubleshooting

Sleeve is too tight to slide on

Ensure you are using the correct diameter sleeve for your application. If slightly too small, you can carefully slit the sleeve lengthwise and wrap it around the component, securing it with high-temperature tape or clamps.

Material seems to be degrading under extreme heat

Verify that the temperature exposure does not exceed the continuous (250°C) or short-term (1200°C) limits. For applications exceeding these limits, consider specialized thermal shielding.

Sleeve is difficult to cut cleanly

Use a sharp pair of heavy-duty shears or a utility knife. A hot knife can also be used for a cleaner cut on some materials, but exercise caution and ensure proper ventilation.

Pros and Cons

Pros

  • Excellent thermal insulation for sensitive components.
  • Protects against spills and accidental flame contact.
  • Durable and long-lasting material construction.
  • Available in multiple sizes and colors.
  • Easy to cut and install on existing wiring or hoses.

Cons

  • Supplied only in 3-foot lengths, which may require joining for longer runs.
  • The 1/2 inch diameter may be too small for larger bundles of wires or hoses.
  • While resistant, not intended for continuous direct flame impingement.
  • May be less flexible than non-coated sleeving options.

Setup, Compatibility & Care

Setup:

  1. Measure and Cut: Measure the length of the component to be protected and cut the Heat Sleeve to the required size using sharp shears or a utility knife.
  2. Install: Slide the Heat Sleeve over the wire, cable, or hose. For components that cannot be disconnected, the sleeve can be slit lengthwise and then secured around the component using high-temperature tape or clamps (sold separately).
  3. Secure: Ensure the sleeve fits snugly and covers the entire area requiring protection.

Compatibility:

  • Designed for use with wires, cables, hoses, and other cylindrical components.
  • Suitable for automotive, marine, industrial, and aerospace applications.
  • Available in various diameters to accommodate different sizes of components. This guide specifically covers the 1/2 inch diameter variant.

Care:

  • Clean the exterior of the Heat Sleeves with a damp cloth if necessary. Avoid using harsh chemicals or abrasive cleaners.
  • Inspect regularly for any signs of damage, such as tears or delamination, and replace if compromised.
