The Coilhose Pneumatics N12-50 coiled nylon air hose has a 1/2" ID and is 50 ft. long. The hose is a single-component tube made of yellow Nylon 11 for resistance to moisture absorption, abrasion, fatigue, chemicals, and extreme temperatures. It is capable of functioning effectively at temperatures ranging from -60 to +200 degrees F at a maximum working pressure of 170 pounds per square inch (psi), and comes equipped with two 1/2" factory-installed, brass male National Pipe Thread Taper (NPT) strain relief rigid fittings. This hose is manufactured as a lighter-weight alternative to bulkier rubber and plastic hoses for use in a wide range of industrial applications, such as manufacturing, auto repair, robotics, and others.Industrial hoses transfer or convey air or liquid in hose systems. When selecting industrial hoses, use the STAMPED method: S = Size (ID, OD, and length) T = Temperature (maximum and minimum temperatures of material being transported) A = Application (industry or process) M = Material (to be conveyed, type and concentration) P = Pressure (maximum working pressure) E = Ends (type of end connectors or couplings on hose) D = Delivery method (volume and velocity)The inside diameter of the hose must be adequate to keep pressure loss to a minimum and avoid damage to the hose due to heat generation or excessive turbulence. The hose must be capable of withstanding the minimum and maximum temperatures that occur within the hose system. Some applications require specialized oils or chemicals to be conveyed through the system. In this case, hose selection must ensure compatibility of the hose tube, cover, couplings and O-rings with the fluid used. Industrial hoses are used in systems such as air compressors, automatic manufacturing operations, aircraft controls, and tire installation in industries including agriculture, mining, road construction, firefighting, and aviation.Coilhose Pneumatics manufactures air tool products and accessories such as hoses, tubing, fittings, lubricants, and blow guns. The company, founded in 1969, is headquartered in East Brunswick, NJ.
