This is the best air hose we've ever tested - and our all-around favorite - based on excellent durability, non-kinking flexibility and easier-to-handle weight. Designed and manufactured specifically to stand up to ultra high-stress applications for professionals who demand the highest reliability in air supply. Lighter and less-bulky than traditional high-burst hose, extra strength is braided into the hose during manufacture. Solid-brass fittings with soft-grip collars provide extra protection at the point most ruptures occur. When you consider the cost and frustration of replacing burst hose, it's the best value air hose on the market. 50-feet of 1/4" outside-diameter hose with two male 3/8" NPT ends.
