Crushproof Tube Exhaust Hose

The Original Crushproof Exhaust Hose

Crushproof Tubing Company didn't just enter the exhaust hose market — they created it. Since 1949, the Ohio-based manufacturer has been producing what became the world's first crush-proof garage exhaust hose for the automotive aftermarket, and that founding mission still defines every product they make today. For professional technicians and shop owners looking at the full exhaust hose category, Crushproof is the benchmark against which other products are measured.

What Makes Crushproof Exhaust Hoses Different

The engineering story behind these hoses starts with a single, elegant idea: eliminating the wire helix. Crushproof hoses feature a unique wire-helix-free design that ensures they return to their original shape after being run over or crushed, making them ideal for use in garage exhaust systems. In busy service bays where vehicles and equipment constantly move over floor-mounted hoses, this resilience is critical. The wire-helix-free design not only makes Crushproof exhaust hoses ultra-flexible but also ensures ease of maneuverability, making them ideal for tight spaces or areas with limited access.

Heat resistance is the other defining characteristic. Manufactured using heat-resistant rubber capable of withstanding temperatures up to 600°F, these hoses offer superior heat resistance and flexibility compared to standard metal or plastic hoses. That temperature rating gives shops the confidence to handle everything from everyday passenger cars to high-output diesel equipment without worrying about hose degradation over time.

Key Product Lines

Crushproof's exhaust hose lineup addresses a range of shop environments and vehicle types:

• ACT Hose: The Crushproof ACT Hose is a heavy-duty garage exhaust hose engineered for larger vehicles including trucks, vans, and diesel-powered equipment. It is purpose-built for demanding environments where the hose may rest on the floor or run through underground exhaust extraction systems. These are available without a wire helix, and come in 4, 5, and 6 inch diameters.
• Flarelock Exhaust Hose (FLT400): The Crushproof FLT400 Flarelock Exhaust Hose highlights the brand's commitment to innovation and reliability in creating solutions for exhaust management.
• Dynamometer Exhaust Hose: This series of exhaust hose is made of a blend of rubber that can withstand the high temperature of a dynamometer when used with a fan-assisted system.
• AFLT300 Flexible Exhaust Hose: The flexible AFLT300 Exhaust Hose exemplifies the brand's dedication to providing high-quality, practical solutions tailored to professional environments.

With 2"–6" standard sizing, garage exhaust hoses are ideal for overhead, underground, or on the floor installation. A full suite of accessories — including adapters, splice connectors, Y-assemblies, and door ports — rounds out the system. Crushproof provides exhaust hose adapters for tailpipes and stacks from 2" to 12".

Built for Professional Environments

Maintaining clean air in a working environment is important for the health and safety of workers involved in the automotive service industry. Hazardous chemicals that escape through the exhaust of diesel engines, especially carbon monoxide, bring serious health issues to those who are inhaling it continuously. Crushproof exhaust hoses address this directly, designed to capture and expel fumes at the source before they can accumulate in the workspace.
