BSTFLEX specializes in the production of high-performance thermal insulation materials for automotive applications, offering a wide range of insulating sleeve for exhaust hose designed to withstand extreme temperatures, resist abrasion, and extend the life of hoses, cables, and lines exposed to harsh environments.

Versatile Material Options for Maximum Performance

Our exhaust hose insulating sleeves are available in multiple high-temperature materials to meet diverse performance needs:

• Silica Sleeve: Engineered for ultra-high temperature applications, silica fiber sleeves offer outstanding thermal resistance up to 1000°C (1832°F), making them ideal for turbocharged exhaust systems and industrial engines.

• Fiberglass Sleeve: A cost-effective solution for general thermal protection, fiberglass sleeves can handle continuous exposure up to 540°C (1000°F), while providing reliable insulation and moderate abrasion resistance.

• Silicone-Coated Fiberglass Sleeve: Designed for applications requiring splash protection and flexibility, these sleeves feature a fiberglass core with a thick, flame-retardant silicone rubber coating. They repel oils, water, molten splash, and contaminants, making them ideal for hydraulic and exhaust lines near high-heat sources.

• Basalt Sleeve: Woven from naturally fire-resistant basalt rock fibers, these sleeves combine excellent thermal stability with superior mechanical strength and chemical resistance. With a temperature tolerance up to 982°C (1800°F), basalt sleeves are perfect for diesel exhaust hoses, generator sets, and marine engines.

Construction Types to Fit Your Needs

• Knitted Sleeves: Offer superior elasticity and conformability, allowing easy installation over complex or irregularly shaped exhaust systems. Ideal for aftermarket applications and tight spaces.

• Braided Sleeves: Provide maximum durability, high tensile strength, and enhanced abrasion resistance. These are commonly used in OEM applications where long-term reliability is critical.

Applications

BSTFLEX insulating sleeves are used across a wide range of industries and applications:

• Automotive exhaust hoses and downpipes

• Heavy-duty trucks and buses

• Diesel-powered machinery and generators

• Marine exhaust systems

• Construction equipment and mining vehicles

• High-performance racing engines

Whether you need high heat resistance, mechanical protection, or both, BSTFLEX provides a tailored solution with the right combination of material and sleeve structure.
