GOST 5398-76 Rubber Suction and Delivery Hose
● The main body is made of Natural Rubber (NR), with an inner lining reinforcement layer to enhance fuel corrosion resistance.
● Without metal braided reinforcement layer (none or fiber reinforcement)
● After soaking in gasoline for 72 hours: volume expansion rate ≤ 25%, tensile strength retention rate ≥ 80%
● Specially designed for conveying petroleum-based liquids: including hydrocarbon media such as gasoline, diesel, kerosene, lubricating oil, hydraulic oil, etc.; applicable for oil delivery in oilfield drilling equipment, pipeline systems in refineries, and fuel supply pipelines for industrial machinery.
