Ultimate Guide to SAE 100R4 Hydraulic Hose: Specifications, Features & Applications

Hydraulic systems demand high-quality hoses for effective fluid transfer, and the SAE 100R4 hose is a trusted option for low-pressure, high-temperature applications. In this guide, we’ll explore what makes the 100R4 hydraulic hose essential for many industries, break down the 100R4 hose spec, and explain why choosing the right R4 hydraulic hose matters.

What Is a 100R4 Hydraulic Hose?

The 100R4 hydraulic hose is designed specifically for low-pressure hydraulic suction and return lines. It features a textile reinforcement with a steel wire helix, giving it strength and flexibility. This type of hose is typically used in industrial and mobile equipment such as tractors, dump trucks, and loaders. Because of its special construction, it resists vacuum collapse and is ideal for suction applications involving petroleum-based and water-based hydraulic fluids.

Key 100R4 Hose Spec and Construction

Understanding the 100R4 hose spec helps in selecting the right hose for your needs. According to the SAE 100 R4 hose specifications, the construction includes:

• Tube: Oil-resistant synthetic rubber
• Reinforcement: Textile braid with a steel wire helix
• Cover: Oil and weather-resistant synthetic rubber
• Temperature Range: -40°F to +212°F (-40°C to +100°C)
• Pressure Range: Up to 300 psi, depending on hose size
• Vacuum Rating: Excellent vacuum resistance due to wire helix

These features ensure the R4 hydraulic hose performs reliably in demanding environments while resisting oil, heat, and abrasion.

Applications of the R4 Hydraulic Hose

The R4 hose is commonly used in:

• Hydraulic suction and return lines
• Fuel and lubrication lines
• Low-pressure applications where flexibility and durability are required
• Equipment that requires vibration resistance and easy routing

The SAE 100R4 hose specifications make it suitable for industries such as agriculture, construction, and manufacturing, where durability and safety are paramount.
