Basalt Fiber Fire Sleeve is a premium thermal protection sleeve constructed from braided basalt fiber and coated with high-temperature silicone rubber. Compared with standard fiberglass fire sleeves, basalt fiber sleeves offer improved mechanical strength, enhanced abrasion resistance, and greater thermal stability under prolonged exposure to harsh industrial environments.
Designed for hydraulic hoses, fuel lines, cables, wiring harnesses, and industrial piping, the sleeve helps protect critical systems from flame, radiant heat, molten splash, and mechanical wear.
LXHTR Basalt Fiber Fire Sleeves are engineered for applications where conventional fiberglass fire sleeves may not provide sufficient durability or service life.
The natural basalt fiber core offers superior resistance to thermal shock, vibration, and abrasion, making it particularly suitable for steel mills, foundries, mining equipment, heavy machinery, power generation facilities, and other demanding industrial environments.
The silicone-coated outer layer provides additional protection against oil, moisture, chemicals, and molten metal splash while maintaining flexibility for easy installation.
Why Basalt Fiber?
Many fire sleeves use fiberglass as the reinforcement layer. Basalt fiber offers a higher substrate temperature resistance of up to 760°C (1400°F), providing improved thermal stability and mechanical integrity when exposed to extreme heat conditions.
Although the silicone coating determines the sleeve’s continuous operating temperature, the basalt fiber core helps maintain structural strength during short-term high-temperature exposure and thermal shock events.

1. Why choose basalt fiber instead of fiberglass?
Basalt fiber provides higher mechanical strength, better abrasion resistance, and improved thermal stability, making it suitable for more demanding industrial environments.
2. Is basalt fiber more environmentally friendly?
Basalt fiber is produced directly from natural volcanic rock and generally requires fewer additives during manufacturing, making it a more environmentally friendly alternative to traditional fiberglass.
3. Is the sleeve resistant to oil and chemicals?
Yes. The silicone rubber coating provides good resistance to oils, moisture, and many industrial chemicals.
4. Can custom sizes be manufactured?
Yes. Custom diameters, lengths, colors, and packaging options are available.
