Basalt Fiber Thermal Protection Sleeve

Continuous Temperature: up to 750°C / 1382°F*

Construction: Knitted Basalt Fiber

Design: Flexible & Expandable

Protection: Thermal • Heat • Flame • Abrasion

Although exhaust systems are a major application, the same material concept can be applied wherever high‑temperature pipework or components are positioned close to heat‑sensitive systems.

Automotive: Exhaust pipes / turbo systems / wiring / sensors.

Marine: Engine exhaust / generators / hydraulic lines.

Power Generation: Generator exhaust / engine compartments / cables.

Construction: Engine exhaust / hydraulic systems / wiring.

Mining: Heavy equipment / exhaust / hydraulic hoses.

Industrial Machinery: Hot pipework / hoses / cables / process lines.

Metallurgical Equipment: High‑temperature pipework and surrounding components.

Basalt fiber sleeve applications reported by manufacturers and basalt‑fiber suppliers extend beyond exhausts into hydraulic hoses, oil lines, fluid‑transfer pipes, cables and high‑temperature industrial equipment.

A hot exhaust pipe creates two problems.

Problem 1 — You lose valuable heat.
Heat escapes from the exhaust system before the gases reach the catalytic converter or downstream treatment system.

Problem 2 — Everything around the pipe gets hotter.
Wiring, hoses, sensors, plastic components and nearby structures can be exposed to excessive radiant and conductive heat.

Basalt Fiber Sleeve helps solve both.

Inside the sleeve:
Help retain exhaust heat.

Outside the sleeve:
Reduce heat exposure to surrounding components.

This thermal‑containment principle is specifically used on exhaust systems to help maintain exhaust‑gas temperature and protect nearby components.

Born from Volcanic Rock. Built for Extreme Heat.

Basalt fiber is produced from natural basalt rock and offers a combination of high‑temperature resistance, chemical stability, strength and flexibility.

Unlike a rigid thermal barrier, the knitted construction can conform around:
Straight pipes
Bends
Elbows
Flanges
Flexible exhaust sections
Irregular pipe geometries

Professional basalt sleeve products use knitted constructions specifically because they can expand and conform around difficult shapes during installation.

🔥 Exhaust Heat
Wrap hot exhaust pipes to help retain heat and reduce heat radiation into the surrounding engine compartment.

⚡ Sensitive Electrical Components
Protect wiring, sensors and electrical components positioned close to hot exhaust systems.
This becomes particularly important when modern equipment has less available space and more electronics packed around the engine.

🛢 Hydraulic & Oil Hoses
Create a thermal barrier between hot pipes and nearby hydraulic hoses, oil lines and fluid‑transfer lines.

🔧 Industrial Pipework
Protect nearby equipment from high‑temperature pipe surfaces in industrial machinery and process systems.

🚛 Heavy‑Duty Vehicles
Basalt knitted sleeves are already used across heavy vehicles, construction, mining, marine engines and power‑generation applications: retain exhaust heat → support downstream exhaust treatment → reduce heat exposure around the exhaust.
