The LEADFLEX ISO18752-628 Hydraulic Hose is a premium fluid transfer product developed by LEAD-FLEX, a trusted name in industrial hoses. Fully compliant with the ISO18752 standard, it is engineered to meet the rigorous demands of hydraulic systems across industries. Its construction centers on an oil synthetic rubber inner tube—a material chosen for its exceptional resistance to hydraulic fluids, preventing swelling or degradation that can disrupt flow. Surrounding this inner tube are four layers of spiral wire reinforcement, a structural key that boosts pressure tolerance and reduces deformation under load. The outer layer is an oil and weather resistant rubber cover, shielding the hose from outdoor elements, oil spills, and mechanical abrasion. This combination ensures consistent performance in both indoor industrial settings and outdoor job sites.
Product Advantage
Stable Working Pressure: Unlike generic hoses, the LEADFLEX ISO18752-628 maintains a stable working pressure across all size options, eliminating performance fluctuations in critical hydraulic operations.
High Impulse Cycle Resistance: The spiral wire reinforcement enables exceptional impulse cycle resistance—with series like AC, BC, CC, and DC offering varying durability levels (from hundreds of thousands to over a million cycles), reducing replacement frequency.
Wide Temperature Tolerance: It operates reliably from -40℃ to +120℃, making it suitable for cold warehouses and hot construction sites alike. For water conveyance, it stays stable between 0℃ and 70℃, expanding its usability.
Oil & Weather Protection: The oil and weather resistant outer cover prevents premature aging, ensuring longevity in oil-rich environments like manufacturing plants or mining sites.
Customization Support: Customization on specific parameters is available, allowing tweaks to length, diameter, or material properties to fit unique application needs.
Product Uses
This hose is designed exclusively for conveying hydraulic fluids in industrial and mobile systems. Its primary uses include transporting glycol, mineral oil, lubrication fluids, emulsions, and hydrocarbons—all common in hydraulic machinery. Key applications include:
Industrial Machinery: Hydraulic lines in presses, injectors, and assembly lines, where consistent flow is critical.
Construction Equipment: Excavators, loaders, and cranes, where durability against harsh conditions is essential.
Agricultural Machinery: Tractors and harvesters, where temperature flexibility and weather resistance matter.
Important Note: It cannot convey phosphate ester groups, as these fluids damage the inner tube.
FAQ
What fluids can this hose safely convey?

Technical Parameters
The LEADFLEX ISO18752-628 Hydraulic Hose uses high-grade materials to prioritize performance. The oil synthetic rubber inner tube ensures compatibility with most hydraulic fluids, while four-layer spiral wire reinforcement provides structural integrity to handle pressure demands. It is offered in AC, BC, CC, and DC series, each optimized for different impulse cycle needs—with the DC series excelling in high-temperature scenarios. The outer rubber cover resists oil, weather, and abrasion, and all versions comply with the ISO18752 standard, guaranteeing alignment with global benchmarks for working pressure, burst pressure, and bend radius. Its minimum bend radius is designed for flexible installation in tight spaces, and it works seamlessly with standard hydraulic fittings to avoid compatibility issues.
