1. Wider Temperature Range
RFH can handle higher temperature than 2-ply neoprene/fabric ducting. RFH is rated from -60 to 275 F continuous, intermittent to 300 degrees. RFH Plus to 325 degrees.

2. Superior Chemical Resistance
RFH can handle MEK, Toluene, acetone, and sulfuric acid fumes.

3. No Cement
RFH is constructed without the use of cements, solvents, adhesives, glues or chemicals. High temperatures and chemicals can attack the glues used in fabric ducting.

4. Better Abrasion Resistance
RFH offers 2-3 times more abrasion resistance than all cloth products.

5. Better UV, Moisture & Weathering Resistance
RFH is thermoplastic rubber and does not age or absorb moisture like fabric ducting.

6. Flex Fatigue
Neoprene/fabric hose begins to flake off small bits of the neoprene coating when subjected to repeated flexing.

7. Airtight
RFH is extruded thermoplastic rubber and is airtight. Fabric ducting develops pin holes and is not airtight.

8. Versatile
Because RFH has better chemical resistance, better temperature range, better abrasive resistance, and better flex fatigue it can solve more applications. It allows you to stock fewer product types and reduces inventory requirements.

9. Special Colors
RFH is available in White, Blue, Yellow, Gray.

10. Wearstrip Available
RFH is available with a tough ridged high density polypropylene wearstrip that is molecularly bonded to the hose, not an additional layer of fabric glued on like fabric ducting.

The Super Vac-U-Flex was designed to offer maximum flexibility and strength while providing an aesthetically appealing and unique construction. The hose consists of a coated wire helix with a single ply cover. Polyester reinforcing yarns are laid longitudinally and radially to provide additional strength. A second ply of material is extruded over the yarns and inner cover. This construction offers excellent helix-to-cover adhesion and a smooth interior for superior air flow characteristics.

Available in a wide range of colors, internal diameters (1 ¼” – 6”) and in lengths up to 50’. Molded-on end fittings that are fused together to create an airtight seal are available as well as the standard screw-on type end fittings.

A great strength of Hi-Tech Duravent is our capability to customize any hose to the color, diameter, and length that is perfect for the OEM or any other consumer.
