This is a Heavy-Duty Crush-Resistant Exhaust Hose designed for automotive ventilation systems. Built with a TPV (thermoplastic vulcanizate) double-helix memory construction, it resists kinking and wall collapse—even under vehicle traffic.

Rated for continuous service up to 350 °F (intermittent up to 600 °F), this 4″ ID × 25′ hose reliably vents harmful vehicle emissions in active garage environments.
