Bulk solids – air hose can be made to carry bulk granular or pelletized solids in an air or gas stream. These tubes must be able to withstand the abrasive action of solids moving through the interior.
Compressed air – air hose can be made for larger pneumatic systems. These vessels must have high strength and strong seals to prevent leaks or damage. When being used with tools and equipment that are oil-lubricated, the hose must be able to resist oil mist corrosion.
Other gases – air hose can be made to carry a wide variety of different gases for heating and cooling as well as industrial, medical, and semiconductor applications. These hoses require resistance to the corrosive nature of the chemicals they transport.
Anti-static : Hoses are conductive or semi-conductive to prevent the buildup of static electricity.
Coiled : Hose is coiled for flexibility and elasticity, making it expandable and relatively easy to store.
Corrugated : Hose contains corrugations, pleats, or spiral convolutions to increase flexibility and the capacity for compression and elongation.
Crush-proof : Hoses are designed to resist crushing or collapse caused by exterior forces. This is important for applications where flow interruption or kinking could cause serious system damage.
Flame resistant : Hoses are constructed to maintain their integrity in the presence of flame or fire.
Lay-flat : Lay-flat hose is designed to default to a flat, collapsed (not rigid) structure when not filled with fluid. This feature is less common in air hoses and air duct hoses.
Reinforced: Reinforced hoses are constructed with some type of reinforcement that provides additional strength.
