100R2AT Hydraulic Hose

The numbers on a hydraulic hose, such as SAE 100R1AT or SAE 100R2AT, refer to specific standards and specifications set by the Society of Automotive Engineers (SAE). These numbers provide important information about the hose’s construction, performance, and suitability for different applications.

Here’s a breakdown of what the numbers typically represent:

• SAE 100: This indicates that the hose is part of the SAE 100 series of hydraulic hoses, which are designed for industrial and mobile hydraulic applications.
• R: This letter usually signifies that the hose is reinforced with wire or textile.
• 1 or 2: These numbers typically indicate the hose’s burst pressure rating. A higher number generally means a higher burst pressure.
• AT: This combination of letters often refers to the hose’s reinforcement type and other specific characteristics, such as its operating temperature range or resistance to certain chemicals.

By understanding the meaning of the numbers on a hydraulic hose, you can make informed decisions about selecting the right hose for your specific needs and ensure safe and efficient operation of your hydraulic system.

The primary difference between SAE 100R1 and 100R2 hydraulic hoses lies in their burst pressure ratings.

• SAE 100R1: This hose has a lower burst pressure rating, typically around 4,200 psi. It is suitable for many general-purpose hydraulic applications where lower pressures are sufficient.
• SAE 100R2: This hose has a higher burst pressure rating, typically around 5,000 psi. It is designed for applications that require higher hydraulic pressures, such as heavy-duty machinery or specialized equipment.

Both SAE 100R1 and 100R2 hoses are reinforced with wire and share similar operating temperature ranges and resistance to abrasion, oil, and grease. However, the choice between the two depends on the specific requirements of your hydraulic system, particularly the maximum operating pressure.

The pressure rating of a R2 hydraulic hose is typically around 5,000 psi. This means it can withstand a burst pressure of up to 5,000 pounds per square inch before failing.

However, it’s important to note that the exact pressure rating can vary slightly depending on the specific hydraulic hose manufacturer and the other components of the hose assembly.
