Product Overview
The LEAD-FLEX HYDRAULIC OIL DELIVERY HOSE is a specialized product for hydraulic oil transfer, focusing on hydraulic return pipes. Developed by LEAD-FLEX, it balances strength and flexibility to meet the unique needs of return systems. Its construction features an oil-resistant inner tube—a material that withstands hydraulic oil without degradation, ensuring smooth flow. The hose includes a lightweight reinforcement layer that provides strength for system pressures while maintaining flexibility. The outer layer is an oil-mist resistant rubber cover, protecting against oil mist (common in hydraulic systems) and minor abrasion—making it perfect for return pipes.
Product Advantage
Oil Mist Resistance: The oil-mist resistant outer cover prevents oil mist buildup (a hydraulic system byproduct) that degrades generic hoses, extending service life.
High Flexibility: It is highly flexible, making it easy to route around machinery components and fit into tight spaces in hydraulic systems.
Oil-Resistant Inner Tube: The oil-resistant inner tube is compatible with all hydraulic oil types, preventing swelling or leaks.
Long Service Life: The combination of oil-resistant materials and oil-mist protection ensures a long service life, reducing maintenance costs.
Easy Installation: Its lightweight design makes it easy to handle and install, saving time during system upgrades or repairs.
Stable Performance: It maintains stable performance across conditions, ensuring consistent hydraulic oil delivery in return pipes.
Technical Parameters
The LEAD-FLEX HYDRAULIC OIL DELIVERY HOSE uses return pipe-optimized materials. The oil-resistant synthetic rubber inner tube is compatible with all hydraulic oil types, while the reinforcement layer provides strength without sacrificing flexibility. The oil-mist resistant outer cover repels oil mist, and the hose is available in multiple inner diameter options to match flow rates. All versions have a minimum bend radius for tight installations and comply with industry standards for working pressure and burst pressure, ensuring safe return pipe operation.

Product Uses
This hose is designed for hydraulic oil delivery in return pipes (which carry used oil back to reservoirs). Key applications include:
Industrial Machinery: Return pipes in presses, lathes, and robots, where flexibility around moving parts is needed.
Construction Equipment: Return systems in excavators and loaders, where oil-mist resistance matters.
Automotive Hydraulics: Return pipes in trucks with hydraulic lifts.
Agricultural Machinery: Return systems in tractors, with durability for outdoor farms.
Marine Hydraulics: Return pipes in small boats, where moisture resistance is key.
FAQ
What is this hose’s main use?
It is designed for hydraulic oil delivery in return pipes, which carry used oil back to reservoirs—its flexibility and oil-mist resistance make it ideal for this role.
Is it compatible with all hydraulic oil types?
Yes, its oil-resistant inner tube works with all common hydraulic oil types, preventing degradation.
Why is oil-mist resistance important?
Hydraulic systems produce oil mist, which damages hoses. The oil-mist resistant outer cover prevents buildup, extending lifespan.
Can it fit in tight spaces?
Yes, it is highly flexible with a optimized bend radius, allowing installation in tight hydraulic system spaces.
Can it be used for high-pressure hydraulic lines?
No—it is for low-pressure return pipes. For high-pressure lines, use a specialized hose like the LEADFLEX ISO18752 series.
