Uncoated Fiberglass Braided Sleeves | High-Temperature Flexible Insulation Sleeving

With an operating temperature range from –60 °C up to +648 °C (1200 °F), uncoated fiberglass sleeving provides reliable insulation and mechanical protection in harsh environments. The braided structure offers excellent flexibility, abrasion resistance, and ease of installation, even on irregular or curved components.

These sleeves are self-extinguishing, non-corrosive, and fungus resistant, making them suitable for demanding industrial and electrical applications. They are compatible with all insulation and conductor types and are widely used in high-temperature wire harnesses, cable connections, and component covering where heat resistance and durability are critical.
