The Goodyear Engineered Products Pliovic Plus 300 Blue PVC multipurpose air hose assembly is a nonconductive, general-purpose hose manufactured for carrying air, water, and a variety of spray solutions. Its tube and non-marking blue cover (which is thicker than standard Pliovic hose covers) are both constructed with Rubber Manufacturers Association (RMA) Class B Pliovic (PVC, polyvinyl chloride) for medium oil resistance, which means that both components will undergo a maximum volume change of +65% and will retain a minimum of 50% of their tensile strength after exposure to oil. This hose is also resistant to weathering, abrasion, moisture, alkalis, and weak acids, and is reinforced with spiral synthetic yarn for the strength necessary to reach and maintain its maximum pressure rating of 300 psi. It is rated with a minimum electrical resistance greater than one (1) megohm per inch of hose length at 1,000V DC, and is capable of functioning effectively at temperatures ranging from -10 to +158 degrees F (-23 to +70 degrees C). This hose comes equipped with two factory-installed brass NPT male couplings, and is suitable for a wide range of industrial, construction, and agricultural applications. Industrial hoses transfer or convey air or liquid in hose systems. When selecting industrial hoses, 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 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.
