The OEM Automotive Tools ViperFlex 3/8" by 50' Air Hose, No. 24423, is made from composite materials, making it both durable and flexible in weather conditions ranging from -30 to 150 degrees F. With an abrasion-resistant outer cover and bend restriction to reduce wear and tear, the hose retains no memory of being coiled, allowing it to lay out flat, and it does not kink. It has a 1/4" brass M by M NPT connector on both ends and behind the restrictor. The hose, available in multiple sizes, features 300 psi working pressure and comes with a limited lifetime warranty.
