The Campbell Hausfeld retractable hose reel (PA500400AV) includes a 9.5mm (3/8-inch) x 15M (50-foot) PVC air hose that’s spring loaded for easy retraction and storage in the durable, crack-resistant case. The case is portable and also can be mounted on a flat surface. The heavy-duty air hose is designed for long life, has a non-marring, abrasion-resistant cover, and can be used in a wide range of temperatures: from 35 degrees to 250 degrees F. 300 PSI maximum working pressure. A built-in bend restrictor helps prevent hose kinks. Use the 750mm (2-1/2) foot leader to connect the hose to an air compressor.
