The Honestflex SAE100R7/EN855 R7 hydraulic hose is a medium-pressure hydraulic hose designed and manufactured according to the international standards of SAE 100R7 and DIN EN855 R7. It is precision-machined from all thermoplastic materials and is an ideal upgrade and replacement for traditional rubber hoses. This hose features a three-layer composite structure: the inner layer is composed of high-performance polyester elastomer (or polyamide), possessing excellent oil and chemical resistance, suitable for conveying petroleum-based hydraulic oils, synthetic ester oils, and water-based hydraulic fluids; the reinforcing layer is composed of a layer of high-tensile-strength synthetic fiber braid, ensuring the hose maintains good flexibility and dimensional stability while withstanding medium to high pressures; the outer layer is covered with highly flexible polyurethane (or nylon) material, the surface of which is usually needle-punched to release moisture, and is MSHA (Mine Safety and Health Administration) certified, possessing flame-retardant, abrasion-resistant, ozone-resistant, and UV-resistant properties. This hose is suitable for temperatures ranging from -40℃ to +100℃, with a safety factor of 4:1, making it an ideal choice for agricultural machinery, material handling equipment, and industrial hydraulic systems.
SAE100R7/EN855 R7 hydraulic hoses, due to their lightweight, flexibility, and non-conductive properties, are widely used in various hydraulic systems with special requirements for cleanliness, flexibility, and electrical insulation. Specific applications include:
Agricultural Machinery and Irrigation Equipment: Widely used in the hydraulic control circuits of tractors, combine harvesters, sprayers, and irrigation systems, resistant to sun exposure, moisture, and chemical contact during field operations.
Material Handling and Storage Equipment: Suitable for the hydraulic systems of forklifts, telescopic boom trucks, lifting platforms, and stacker cranes, especially suitable for gantry piping layouts with pulley and mast systems.
Industrial Hydraulics and Lubrication Systems:Widely used in hydraulic control and centralized lubrication systems for machine tools, presses, and automated production lines, resistant to long-term contact with mineral oils and synthetic lubricants.
Medium-Pressure Gas Transportation: Can be used for transporting compressed air, industrial gases, and some solvents; selection requires confirmation based on media compatibility.
Marine and Offshore Equipment:Some enhanced models can be used in ship deck machinery and port equipment, resistant to salt spray corrosion and high humidity environments.
Lightweight design, easier operation: The low density of thermoplastic materials means the hose weighs only about 50% of a comparable rubber hose, significantly reducing installation difficulty and operator workload. It also helps reduce the weight of mobile equipment and improve fuel economy.
Non-conductive properties, safety assurance: The outer layer and overall structure have natural electrical insulation properties, making it suitable for scenarios with strict electrical safety requirements, such as aerial work platforms and areas near electrical equipment, without the need for additional insulation.
Small bending radius, flexible routing: The excellent flexibility of thermoplastic materials results in a minimum bending radius much smaller than that of a comparable rubber hose, facilitating routing in confined spaces, reducing the number of joints, and lowering the risk of leakage.
Compact outer diameter, strong adaptability: Under the same inner diameter conditions, thermoplastic hoses have a smaller outer diameter, facilitating side-by-side laying in multi-pipe systems. They can also be manufactured in double or multi-joint structures, avoiding friction between hoses.
Excellent wear resistance: The outer polyurethane layer has 5-10 times the wear resistance of rubber, effectively resisting mechanical friction, dragging, and gravel abrasion, significantly extending the hose's service life under harsh conditions.
Excellent chemical corrosion resistance: It exhibits good resistance to mineral oils, synthetic esters, water-based hydraulic fluids, solvents, and alkaline media, and is not prone to swelling, embrittlement, or aging, offering broad media compatibility.
Ozone resistance and weather resistance: Thermoplastic materials themselves possess excellent ozone, UV resistance, and aging resistance properties. Long-term outdoor exposure will not cause cracking, fading, or hardening, making it suitable for all-weather operation.
