The RFH Ultra hose by Hi-Tech Duravent

Hi-Tech Duravent is known for its impressive lineup of industrial hoses and ducting for a wide range of tasks. One of its more versatile products is the RFH Ultra, a lightweight and highly flexible hose made out of thermoplastic rubber reinforced with yarn and supported by a coated spring steel helix.

This black hose is the perfect choice for several applications in a broad variety of settings, such as air handling in harsh environments, fume removal, cotton harvesting, and air conveyance.

Good oil and chemical resistance

Among the notable advantages of the RFH Ultra are its strong oil and chemical resistance and its superior weathering and aging properties. This flexible hose also can resist abrasion, moisture, ozone, and ultraviolet rays, and it is usable in temperatures ranging from -51 to 135 degrees Celsius.

Hi-Tech Duravent particularly recommends the RFH Ultra for use in the agriculture sector. Other relevant applications include vacuum systems, dust collectors, smoke removal, venting and cooling of industrial equipment, and wood sawdust. Among the many special features are the following:

• smooth interior;
• low pressure resistance;
• excellent flex fatigue resistance
• compliance with UL94-HB flame standard; and
• optional screw cuffs, available separately.

Based on straight hose lengths used in an ambient temperature of 22 degrees Celsius, this hose has a working vacuum of 14 inches of mercury and working pressures ranging from nine to 31 pounds per square inch. It is available in seven different inner diameters, from 25.4 to 152.4 millimetres, and in standard lengths of 25 and 50 feet.

The RFH Ultra is not Hi-Tech Duravent’s sole option in terms of versatile thermoplastic rubber hoses, of course. The manufacturer also carries three other types of black RFH hoses with varying diameter ranges, as well as the orange and black RFH-W. Another similar choice is the black and white ARH, ideal for conduit applications in municipal work projects. Accessories available include bridge clamps, duct connectors, quick-release clamps, and screw clamps.

For a strong, damage-resistant, flexible hose that can work for many purposes, trust in the RFH Ultra.
