This highly flexible suction and discharge hose is engineered for the safe and efficient transfer of liquid products in the petrochemical sector, handling substances with aromatic content up to 60%. Perfectly suited for tank trucks transporting diesel, ethanol, gasoline, and oils, it combines durability with ease of use. The smooth black Chemigum® (NBR) inner layer ensures excellent resistance to oils, while the robust reinforcement of synthetic cord and dual steel wire spirals guarantees strength and reliability under demanding conditions. Its deeply corrugated Chemivic® (NBR/PVC) outer layer provides outstanding resistance to petrochemicals, oils, greases, and abrasion, while also minimizing drag when the hose is moved across the ground. A built-in copper wire ensures electrical continuity between hose ends when properly connected to fittings, enhancing operational safety. Thanks to its corrugated design, the hose offers exceptional flexibility, requiring minimal effort to bend, with a minimum bending radius equal to its inner diameter. Lightweight construction further simplifies handling, making it an ideal solution for intensive industrial applications. With a working pressure range of 10 to 17 bar (depending on diameter), vacuum resistance up to 0.9 bar, and an operating temperature span from -40°C to +93°C, this hose delivers reliable performance and long-lasting efficiency in the most challenging environments.
