Outside Diameter:3.2700 Inches  |  Inside Diameter String:3 Inches  |  Item Length String:25 Feet  |  Number of Items:1 This Hi-Tech Duravent RFH series pharmaceutical and food hose is made of white thermoplastic rubber for resistance to chemicals, moisture, and ozone, and is suitable for material handling, pharmaceuticals, transferring food and beverages, or exhaust and ventilation applications. The hose is made with Food and Drug Administration (FDA)-approved thermoplastic rubber and it is reinforced with a wire helix for strength and resistance to crushing. It has a temperature range of -60 to +275 degrees F (-51 to +135 degrees C) and can be used with a variety of coupling options (not included). This hose is suitable for ventilation and transferring a range of materials in the health care, pharmaceutical manufacturing, and food and beverage industries, among others.Industrial hoses transfer or convey air or liquid in hose systems. When selecting industrial hoses, use the STAMPED method: 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.Hi-Tech Duravent manufactures flexible hose and ducting for air, fume, and dust collection applications. The company, founded in 1947 as Flexible Technologies, is headquartered in Abbeville, SC.
