Built to Perform in the Harshest Industrial Environments

From mining operations and offshore platforms to desert climates and heavy-duty transport, the HD Lava Tube is designed to safeguard critical wiring harnesses, hydraulic lines, fuel hoses, and control cables from extreme heat and environmental exposure. Constructed from basalt fiber—derived from crushed volcanic rock—this rugged thermal sleeve is naturally resistant to UV, salt, water, oil, chemicals, and acids. It outperforms fiberglass with 25% more tensile strength, making it ideal for high-abrasion, high-temperature industrial applications.

Available in standard sizes and lengths, HD Lava Tube can also be custom-fabricated for OEM production lines or one-off field repairs. Choose between a durable hook-and-loop seam or a heavy-duty metal lacing and wire closure for maximum reliability. Whether you’re protecting systems in open-pit mining trucks, offshore rigs, or utility fleets, HD Lava Tube is engineered to deliver long-term thermal protection under the toughest conditions.
