A pneumatic air hose is formed from an inner elastic tubular member surrounded by an outer inelastic tubular member. In use, one end of the air hose is connected to an air compressor and the end to a pneumatic tool. When engaged, the pneumatic air hose and inner elastic tubular member expand to an extended state while the outer tubular sleeve is extended along with the inner tubular member to a length greater than the original non-extended state. Upon disengagement of the air compressor, the expandable hose resumes its original non-extended state.
