The Amflo 12-50E blue polyurethane air hose has a 1/4" ID and is 50 ft. long. Its blue tube and cover are made of polyurethane, which has non-marring characteristics and provides resistance to weathering, abrasion, oil, and kinks. This hose provides both durability and flexibility at temperatures ranging from -30 to +150 degrees F. It is reinforced with a nylon braid for the strength necessary to reach and maintain its maximum pressure rating of 300 pounds per square inch (psi), and comes equipped with two 1/4" factory-installed, brass male National Pipe Thread Taper (NPT) swivel fittings with PVC (polyvinyl chloride) bend restrictors that reduce twisting and bending, increasing the life of the hose. This hose is manufactured as a lighter-weight alternative to bulkier rubber and plastic hoses for use in contracting and industrial applications.
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.
