Universal, lightweight, highly flexible suction and discharge hose designed for general industrial applications for water and light chemicals, other liquids (excluding fats, oils, and hydrocarbons). It can also be used for air, vacuum transfer of dust and powders – abrasion resistance and potential static electricity issues should be considered. It can be used (at temperatures up to +40°C) for liquid and semi-liquid food products such as juices, beverages, beer, wine, alcohols up to 50% concentration, milk, and dairy products. It is not recommended for oils and fatty food substances. The reinforcement with a steel wire spiral embedded in a soft PVC wall provides good resistance to vacuum and hose collapse. The transparent wall allows for easy visual monitoring of flow. As a hose reinforced only with a steel spiral (without a braid), it exhibits some elongation under pressure, which should be taken into account in applications, especially at elevated temperatures. The METALFLEX PVC hose complies with European regulations 1935/2004/EC, 10/2011/EU (simulants A, B, C, and D1), 2023/2006/EC (GMP), and FDA CFR 21 175.300 and 175.1210. It is suitable for temporary contact with food during the transfer of food substances – under the conditions specified in the manufacturer’s declaration of conformity (available from Tubes International). Hose material: transparent, soft PVC. Reinforcement: galvanized steel spiral. Working pressure for a temperature of 20°C: from 1 bar to 9 bar – depending on the hose diameter. As the operating temperature increases, the working pressure value of the hose decreases. Operating temperature: from -10°C to +65°C.
