The “Neoprene Flex Metal Free” duct hose is a specialty made hose recommended for industrial air movement and fume control applications that require a completely metal-free product. The black flexible ducting is constructed using single-ply neoprene coated polyester fabric. The flex hose is then reinforced with a spiral Polyethylene rod helix that gives the hose its flexibility without sacrificing its shape or rigidity. Polyethylene has a high load bearing capacity and excellent tear resistance. It is also abrasion, oil, and solvent resistant, with a high resistance to sunlight and weather conditions.

As a result of the Polyethylene rod instead of a standard metallic helix, the metal-free flex hose is rendered non-magnetic and cannot be affected by any type of magnetic field. The non-metallic polyurethane rod helix design eliminates sparking and is resistant to corrosion and permanent deformation. Unlike metal, if some weight is applied to the exterior of the hose, the polyethylene rod has the ability to bounce back. In addition, the commercial hose is lightweight, flexible, and easily forms an oval shape for installation in tight spaces. The duct hose offers both efficient flow characteristics and excellent abrasion resistance.

“Neoprene Flex Metal Free” flexible ducting is available in internal diameter sizes ranging from 2-24 inches. This hose is made-to-order with a 300 ft minimum on any ID size. This commercial hose has a working temperature range from -40 to +160 degrees Fahrenheit. Internal diameter tolerances may vary; up to 8 Inches: -0.00 to + 0.125 Inch. 8 Inches and over: – 0.00 to + 0.250 Inch. The flex hose comes in black with a plain cut end. A variety of cuffs are available upon request. The “Neoprene Flex Metal Free” duct hose is applicable to several different markets, including agricultural, cab ventilation, shipyards and dry cleaning.
