SAE100 R12 hydraulic hose is a high-performance industrial fluid transfer solution engineered to meet the rigorous demands of modern hydraulic systems. Manufactured to strict SAE J517 standards, this 4-layer spiral wire reinforced hydraulic hose features a robust construction that delivers exceptional pressure resistance and long-term reliability in challenging operating environments.
Our SAE 100 R12 rubber hydraulic hose consists of three core components: a smooth inner tube made from oil-resistant synthetic rubber, four alternating layers of high-tensile steel wire spiral reinforcement, and a durable outer cover resistant to oil, weather, abrasion, and ozone. This advanced design ensures optimal fluid flow while maintaining structural integrity under extreme pressure conditions.
Designed for versatility, the SAE100 R12 industrial hydraulic hose is suitable for conveying a wide range of hydraulic fluids including mineral oils, lubricants, glycol-based solutions, emulsions, and hydrocarbons. It operates reliably within a broad temperature range from -40°C to +120°C for standard hydraulic fluids, and from 0°C to 70°C when transferring water-based media. Note that this hose is not recommended for use with phosphate ester-based fluids.
The four-spiral wire construction of our SAE100 R12 high-pressure hydraulic hose provides exceptional burst resistance, with working pressures up to 28 MPa (4060 psi) and burst pressures reaching 112 MPa (16240 psi). This makes it ideal for high-pressure hydraulic applications where safety and reliability are paramount.
The oil and weather-resistant outer cover protects against environmental factors such as UV radiation, ozone, and abrasion, significantly extending the service life of the hose. The synthetic rubber inner tube offers excellent resistance to hydraulic fluid degradation, preventing leaks and ensuring consistent performance over time.
Despite its heavy-duty construction, the SAE100 R12 spiral hydraulic hose maintains excellent flexibility, allowing for easy routing and installation in tight spaces. The minimum bend radius specifications ensure that the hose can be installed without compromising its structural integrity or performance.
We offer SAE100 R12 hydraulic hose in a comprehensive range of nominal diameters from 10 mm (3/8") to 51 mm (2"), making it suitable for various flow rate requirements in different industrial applications. Custom sizes and lengths are also available to meet specific project needs.

SAE100 R12 hydraulic hose is widely used across various industries for high-pressure hydraulic fluid transfer applications. It is particularly suitable for:
Construction equipment including excavators, bulldozers, and cranes
Agricultural machinery such as tractors, harvesters, and irrigation systems
Mining equipment and heavy-duty industrial machinery
Marine hydraulic systems and offshore equipment
Material handling equipment including forklifts and conveyor systems
Automotive manufacturing and assembly lines
Oil and gas industry equipment
SAE100 R12 is specifically designed for high-pressure hydraulic applications and features four layers of spiral wire reinforcement, which provides higher pressure resistance compared to braided wire hoses. It meets the SAE J517 standard for hydraulic hoses used in fluid power systems.
No, SAE100 R12 hydraulic hose is compatible with mineral oils, lubricants, glycol-based solutions, emulsions, and hydrocarbons. It should not be used with phosphate ester-based fluids, as these can degrade the rubber components and cause premature failure.
The maximum operating temperature is +120°C for standard hydraulic fluids. When transferring water-based media, the temperature should not exceed 70°C. The minimum operating temperature is -40°C.
The correct hose size depends on the required flow rate and system pressure. Generally, larger diameter hoses are used for higher flow rates, while higher pressure applications require hoses with appropriate pressure ratings. Our technical team can assist you in selecting the right hose size and specification for your specific needs.
