Detailed R2 Hydraulic Hose
R2 Hose Construction:
The R2 hydraulic hose is engineered with a double-wire braid reinforcement, which includes two layers of steel wire woven around the internal tube. This double-braid construction gives improved strength and resilience, making the hose suitable for high-pressure applications. The extra layer of steel wire provides exceptional resistance to pressure and external damage, allowing the R2 hose to manage more demanding functional problems compared to its single-wire equivalents.
Inner Tube: The inner tube is made from rubber or synthetic compounds such as nitrile or synthetic rubber.These materials ensure that the hose maintains its integrity and performance under pressure, have excellent resistance to hydraulic fluids and high pressure.
Reinforcement: The double-wire braid consists of high-tensile steel wires that . The double layer of braid ensures the hose can withstand higher pressures and stresses, minimizing the risk of failure, provide exceptional strength and durability experience for any needs.
Outer Cover: The outer layer is made from robust rubber or synthetic compounds designed to withstand abrasion, weathering, and exposure to chemicals. Materials like neoprene or EPDM are commonly used to protect the hose from external damage and extend its lifespan.
Specifications
Pressure Rating: This high pressure rating makes R2 hoses suitable for more demanding hydraulic systems where high pressure is a regular requirement. R2 hydraulic hoses are designed to handle higher pressures compared to R1 hoses. They typically have a pressure rating ranging from 2,000 to 5,000 psi (pounds per square inch), depending on the hose size and construction.
Flexibility and Bend Radius: Despite its rugged double-wire braid construction, the R2 hose is flexible. The minimum bend radius is typically approximately 5 to 8 times the hose diameter, providing a balance between strength and maneuverability. This flexibility allows it to be installed in tight spaces while maintaining durability under high pressure conditions.
Temperature Range: The R2 hose typically operates effectively over a temperature range of -40°C to +100°C (-40°F to +212°F). This temperature range ensures that the hose remains flexible and functional in a wide range of operating environments. In some cases, specialized R2 hoses are available for a wider temperature range, depending on the materials used.

Pros of Using R2 Hoses:
High Pressure Resistance: Capable of handling significantly higher pressures compared to R1 hoses, making them suitable for more demanding applications.
Enhanced Durability: The double-wire braid provides superior strength and resistance to external damage, extending the hose’s lifespan.
Flexibility: Maintains good flexibility while offering high-pressure performance, allowing for easier installation in various configurations.
Safety: Reduced risk of hose failure under high-pressure conditions, which enhances operational safety and reliability.
Cost: Generally more expensive than R1 hoses due to the additional reinforcement and construction complexity.
Bend Radius: While flexible, the minimum bend radius is larger compared to R1 hoses, which may limit installation in very tight spaces.
Weight: The additional layer of steel braid adds to the weight of the hose, which may be a consideration in applications where hose weight is a factor.
Temperature Sensitivity: While the standard temperature range is broad, extreme temperatures may still affect performance, particularly if the hose is exposed to conditions outside its specified range.
Applications

FAQ
what is R2 hydraulic hose
SAE 100 R2 steel wire reinforced hydraulic hose is suitable for conveying petroleum-based hydraulic oil due to its oil-resistant tube. In addition, it can convey oil products without generating excessive heat and leakage. It is mainly used in some mobile equipment such as agricultural tractors, dump trucks and in-plant hydraulic equipment. It consists of three parts: tube, reinforcement layer and outer layer. The tube is made of oil-resistant synthetic rubber, so it is mainly used for conveying oil products. The reinforcement layer is made of two layers of high-strength braided steel wire, which makes the hose structure strong and resistant to high pressure. Therefore, it has excellent performance in high-pressure working environments. The outer layer is made of high-quality synthetic rubber, which is resistant to weather, ozone, corrosion, abrasion, aging, sunlight and cutting. The hose has a longer service life as a result.
