The Goodyear Engineered Products NR Spray black nylon paint spray hose assembly is suitable for spraying or otherwise conveying a wide variety of paints, chemicals, or solvents in industrial and agricultural applications, and consists of a nylon tube for resistance to chemicals and solvents; and a black RMA Class B (medium oil resistance) synthetic rubber cover for resistance to oil. The cover experiences a maximum volume change of +65% and retains at least 50% of its tensile strength after exposure to oil. This hose assembly is reinforced with braided synthetic yarn for the strength necessary to reach its maximum pressure rating of 750 pounds per square inch (psi). It withstands temperatures ranging from 0 to 190 degrees F (-18 to +88 degrees C), and comes equipped with two factory-installed brass female National Pipe Straight thread for Mechanical Joint (NPSM) fittings. It is suitable for conveying paint, lacquers, thinners, turpentine, air, oil, solvents, or chemicals in spray or other industrial applications.
Industrial hoses and hose assemblies transfer or convey air or liquid in hose systems. When selecting industrial hoses or hose assemblies, use the STAMPED method to help determine the type of hose needed:
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 and hose assemblies 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.
