The Goodyear Engineered Products Horizon 300 Red Jackhammer Hose Assembly has a 3/4" inside diameter (ID) and is 50 ft. in length. Its Versigard (EPDM, ethylene propylene diene monomer) synthetic rubber tube has a Rubber Manufacturers Association (RMA) Class C, limited oil resistance rating, which means that it will undergo a maximum volume change of +100% and maintain at least 40% of its tensile strength after exposure to oil. Its cover is made of red Versigard (EPDM) synthetic rubber for resistance to heat, aging, chemicals, and ozone. This hose is reinforced with spiral synthetic yarn for the strength necessary to reach and maintain its maximum pressure rating of 300 psi (couplings reduce internal pressure capability to 150 psi), and it is capable of functioning effectively at temperatures ranging from -40 to +190 degrees F (-40 to +88 degrees C). It comes equipped with two factory-installed, crimped, iron universal couplings (also referred to as "crowfoot" or "claw" couplings). This hose is manufactured specifically for air tool applications on construction sites, such as jackhammers.
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.
