R4 Oil Hose

Description

The R4 Oil Hose is a robust, heavy-duty hose designed specifically for the suction and discharge of petroleum-based hydraulic oils. It is widely used in low-pressure hydraulic systems, fuel oil transfer, and industrial machinery where oil movement is necessary. This hose is built to provide excellent durability, flexibility, and performance in demanding applications.

1. Construction

• Inner Tube: The inner tube is made from nitrile rubber (NBR) or synthetic rubber, providing excellent resistance to petroleum-based hydraulic fluids, fuel oils, and lubricants. The smooth inner surface ensures optimal fluid transfer with minimal resistance.
• Reinforcement: The hose is reinforced with two layers of synthetic textile braids and a steel wire helix, offering high tensile strength and preventing the hose from collapsing under suction pressure. The steel wire helix also helps the hose maintain its structure during bending or flexing.
• Outer Cover: Made from synthetic rubber, the outer cover is resistant to abrasion, weathering, oil, and ozone. It ensures the hose remains durable even in harsh environmental conditions and provides protection against physical damage.

2. Standard Sizes

• Inner Diameter: Typically available in sizes ranging from 3/4 inch (19mm) to 4 inches (100mm), depending on the required flow capacity and oil volume.
• Length: Standard hose lengths range from 10 to 50 meters, with custom lengths available upon request for specific applications.

3. Working Pressure

• The R4 oil hose is designed for low-pressure hydraulic and oil transfer applications, with working pressures typically ranging from 10 to 15 bars (145 to 217 psi), depending on the diameter and construction of the hose.

4. Vacuum Rating

• The hose is suitable for full vacuum service, with a vacuum rating up to 28 inches of mercury (Hg). The steel wire helix prevents collapse under vacuum pressure, making the hose ideal for suction operations.

5. Temperature Range

• This hose can operate effectively in a wide temperature range, typically from -40°C to 100°C (-40°F to 212°F), making it suitable for use in both cold and hot environments.

6. Performance Characteristics

• Oil Resistance: The nitrile rubber inner tube offers excellent resistance to hydraulic oils, lubricants, and fuel oils, ensuring long-lasting performance without degradation.
• Durability and Flexibility: The combination of textile reinforcement and a steel wire helix ensures flexibility while maintaining structural integrity, making the hose ideal for both suction and discharge applications.
• Abrasion and Weather Resistance: The outer cover is designed to withstand exposure to abrasion, oil, ozone, and weathering, providing a long service life even in outdoor or industrial environments.
• Vacuum and Pressure Capability: The hose is engineered for efficient suction and discharge operations, maintaining its shape under vacuum pressure while handling moderate pressure levels during discharge.

7. Applications

• Primarily used for oil suction and discharge in low-pressure hydraulic systems, fuel oil transfer, and industrial machinery.
• Common in mobile hydraulic units, fuel trucks, oil tankers, and stationary equipment where oil transfer is required.
• Suitable for use in maintenance operations, including draining and refilling hydraulic oil reservoirs.

8. End Fittings

• The hose can be fitted with a variety of end fittings, such as threaded fittings, quick-connect couplings, or flanges, ensuring secure connections to pumps, tanks, and other hydraulic systems.
