Wet-Food and Beverage Hose with Quick-Clamp Sanitary Fittings

Temperature Range: -15° to 155° F
Maximum Vacuum: 29" of Hg @ 72° F
Material: PVC
Color: Clear with White Spiral

Transport milk, syrup, meat, and other wet food and drinks through lines secured with quick-clamp sanitary fittings. This hose is FDA compliant, so you know it's safe to use with food and beverages. Because it's made of PVC, it won't impart tastes or odors to your product. The PVC also won't break down and become brittle from exposure to oil. However, you can't use this hose as part of a high-temperature line. The plastic is clear, so you can easily monitor your flow. A spiral reinforcement ensures the hose keeps its shape when hooked up to a vacuum pump.

The fittings on this hose are 304 stainless steel, so they won't rust from repeated cleaning with water and mild chemicals. Also called tri-clamp fittings, they attach to other quick-clamp fittings with a gasket and a clamp. This type of connection gives you easy access to your line.
