This ultra-light and highly flexible suction and discharge hose is engineered for the safe and efficient transfer of liquid petrochemical products with aromatic content up to 30% (excluding ester-based substances). Its inner layer is made of durable black NBR rubber, ensuring excellent resistance to fuels and chemicals, while the robust reinforcement of synthetic cord combined with two steel spirals guarantees strength, stability, and long-lasting performance under demanding conditions. The outer layer, crafted from black CR rubber, is flame-retardant in compliance with ASTM C 542 standards and provides outstanding protection against abrasion, oil, ozone, and harsh weather exposure. Designed to operate at a working pressure of 5 bar and a vacuum of 0.5 bar, this hose delivers reliable performance across a wide temperature range from -30°C to +120°C. Its lightweight construction and superior flexibility make it an ideal solution for industries requiring safe, efficient, and durable handling of petrochemical liquids.
