Industrial Ducting Hose: 3 in Hose Inside Dia., 25 ft Hose Lg, 8 psi, 4.5 in Bend Radius

Polypropylene duct hoses for air are primarily used on heaters, defrosters, air conditioners, and ventilation equipment in the marine and transportation industries. They meet Federal Motor Vehicle Safety Standard Number 302 (FMVSS 302), which specifies the burn-resistance requirements for materials used inside motor vehicles. These hoses are lightweight, flexible, and crush-resistant. They also resist damage from exposure to chemicals and moisture, are self-extinguishing, and provide good flex-fatigue resistance. The hoses are highly compressible, which saves space when transporting them.

These air duct hoses are primarily used to blow, vacuum, or vent cold or hot air. Some types of duct hoses for air may also be used for moving other materials, such as dust or fumes. The smaller a duct hose's bend radius, the more flexible the hose is. Duct hoses are sometimes known as ventilation hoses, vent hoses, and blower hoses.
