The Continental ContiTech service station air hose is designed for tire inflation service from towers, reels, or curb connections. Its nitrile synthetic rubber tube has a rubber manufacturers Association (RMA) Class b, medium to high oil resistance rating, which means that it will undergo a maximum volume change of +65 percent and maintain at least 50 percent of its tensile strength after exposure to oil. Its cover is made of Red nitrile synthetic rubber for resistance to heat, aging, chemicals and ozone. This hose is reinforced with braided steel wire for strength to REACH its maximum pressure rating of 250 psi, and it is capable of functioning effectively at temperatures ranging from -20 to 190 Degrees F (-29 to 88 Degrees C). it comes with Brass fittings. 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) as a part of the Continental Corporation, the contitech division numbers among the leading suppliers of a host of technical rubber products and is a specialist for plastics technology. Contitech develops, produces and markets high-tech products and systems for the automotive and industrial markets.
