This crystal-clear, highly flexible chemical hose is engineered with a multi-layer construction featuring an inner lining of premium FEP fluoropolymer, ensuring exceptional resistance and complete chemical inertness. Unlike rigid hoses made entirely of Teflon or other fluoropolymers, it offers superior flexibility while maintaining a smooth, non-reactive inner surface that prevents contamination of transported media. Designed to withstand a wide spectrum of aggressive substances, from corrosive chemicals to MEK-based solvents, it fully complies with stringent hygiene standards and is certified for food contact under US FDA 21 CFR 177.1550. Free from phthalates and BPA, non-toxic, and neutral in taste and odor, it guarantees safe use in sensitive applications. The hose can be sterilized with ethylene oxide, making it ideal for industries such as pharmaceuticals, food and beverage processing, chemical transfer, paints, adhesives, inks, toners, fertilizers, pesticides, and even semiconductor production. With a full roll length of 15 m, a working pressure defined by a 1:5 safety factor relative to burst pressure, and a maximum operating temperature of +74°C, it combines durability with reliability. Additional technical parameters include a brittleness temperature of -36°C, hardness of 66° Shore (A), and density of 1.21 g/cm³. Each product is packaged in the Tubes International Clean Room under strict quality standards, ensuring purity and safety, with returns not accepted once the packaging is opened.
