The Goodyear Engineered Products Gorilla Yellow nitrile rubber multipurpose industrial hose is a nonconductive hose manufactured for conveying air, water, oil, petroleum-based solvents, and sprays in industrial, construction, and agricultural applications that require high oil resistance. Its tube is made of nitrile synthetic rubber and its cover is made of yellow Carbryn (carboxylated nitrile) synthetic rubber, both with a Rubber Manufacturers Association (RMA) Class A, high oil resistance rating, which means that both components will undergo a maximum volume change of +25% and will maintain at least 80% of their tensile strength after exposure to oil. The cover of this hose is also Mine Safety and Health Administration (MSHA) approved (2G-14C/14) as flame resistant. This hose is reinforced with spiral Flexten (aramid) synthetic yarn for heat resistance and the strength necessary to reach and maintain its maximum pressure rating of 500 psi, and is capable of functioning effectively at temperatures ranging from -20 to +190 degrees F (-29 to +88 degrees C). It is rated with a minimum electrical resistance greater than one (1) megohm per inch of hose length at 1,000V DC, and can be used with a variety of coupling options (sold separately). This hose is manufactured for a wide range of applications in factories, construction, agriculture, quarries, mines, railroads, the oil and gas industry, and shipbuilding.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.
