Silica Sleeve – Frequently Asked Questions (FAQ)

December 18 , 2025

What is a silica sleeve?

A silica sleeve is a high-temperature protective sleeve made from high-purity silica fibers. It is designed to protect hoses, cables, wires, and pipes from extreme heat, flame exposure, and molten metal splash in industrial environments.

What temperature can a silica sleeve withstand?

Silica sleeves are capable of withstanding continuous temperatures up to 1000°C (1832°F) and short-term exposure to even higher temperatures. This makes them suitable for extreme heat applications where standard fiberglass sleeves are not sufficient.

What are silica sleeves used for?

Silica sleeves are commonly used for:

High-temperature hose protection
Cable and wire thermal insulation
Molten metal splash protection
Fire and flame shielding
Industrial equipment heat protection

They are widely applied in steel mills, foundries, welding environments, automotive exhaust systems, and power generation facilities.

What is the difference between silica sleeve and fiberglass sleeve?

The main difference lies in temperature resistance. A silica sleeve offers significantly higher heat and flame resistance compared to a fiberglass sleeve. While fiberglass sleeves are suitable for moderate temperatures, silica sleeves are preferred for extreme heat and molten metal exposure.

Is silica sleeve fire resistant?

Yes. Silica sleeve material is non-combustible and provides excellent resistance to open flame, sparks, and molten metal splash. It does not melt or burn under normal high-temperature industrial conditions.

Can silica sleeve be used for hydraulic hoses?

Yes. Silica sleeves are often used to protect hydraulic hoses in high-temperature environments where fire risk or radiant heat is present, helping reduce hose damage and improve operational safety.

Is silica sleeve flexible?

Despite its high-temperature performance, a silica sleeve remains flexible, allowing easy installation over hoses, cables, and pipes without restricting movement or system performance.

How is a silica sleeve installed?

Silica sleeves are typically slid over hoses or cables before or after installation. The ends can be secured using clamps, ties, or bands depending on the application and operating conditions.

Does silica sleeve provide thermal insulation?

Yes. A silica sleeve significantly reduces heat transfer from hot surfaces, helping protect nearby components and improving workplace safety by lowering surface temperatures.

Is silica sleeve suitable for outdoor use?

Silica sleeves can be used outdoors, but in applications involving moisture or chemicals, an additional coating or protective layer may be recommended to enhance durability.

Why choose silica sleeve for high-temperature protection?

Silica sleeve is chosen for its exceptional heat resistance, fire protection capability, durability, and reliability in extreme environments. It is one of the most effective solutions for protecting components exposed to intense heat and flame.
