The Continental ContiTech Variflex Red nitrile rubber multipurpose hose is a general-purpose, nonconductive hose manufactured for applications where the need for oil resistance is moderate. Its Rubber Manufacturers Association (RMA) Class A nitrile synthetic rubber tube is rated to undergo a maximum volume change of +25% and to maintain a minimum of 80% of its tensile strength after exposure to oil. Its red cover is resistant to abrasion and ozone, and is made of RMA Class B Chemivic, a Buna-N-Vinyl synthetic rubber that will undergo a maximum volume change of +65% and maintain at least 50% of its tensile strength after exposure to oil. This hose is reinforced with spiral synthetic yarn for strength and it 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 suitable for general purpose applications such as industrial air service, compressor lines, pneumatic tools, low-pressure spray, and others.

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.
