NewAge Industries” Newflex all-PVC tubing is reinforced with spirals that help the tubing flex without kinking, resist crushing, and withstand vacuum applications as high as 28 in./Hg. It works well in pressure applications too. The hose is chemical- and corrosion-resistant and has a smooth inner surface for maximum flow of fluids, air or granular materials. It also allows for visual contact with the flow, which is impossible with wrapped rubber hose. Three styles – heavy, standard, and light duty – mean the user can choose the one that best fits the application. Industrial-grade or food-grade — made from non-toxic ingredients conforming to FDA and 3-A standards — are also available. The tubing is made in the United States and is well stocked in sizes ranging from 3/8” to four inches I.D. Custom sizes and colors are available, as well as cam-operated couplings, barb-style fittings, and clamps for complete hose assemblies.
