Coiled air hose assemblies are lengths of hose that are shaped like a spring. The coils of the hose retract when it is not in use to keep the hose out of the way, save space, and prevent it from dragging on the ground. Coiled hose assemblies are used in applications where the hose will be connected to overhead equipment. Air hose assemblies come with fittings installed on both ends of the hose for connecting the hose to pneumatic tools and equipment. Also known as pneumatic hoses or air compressor hoses, air hoses are used to carry compressed air to the tools and equipment.
