SAE (the abbreviation of Society of Automotive Engineers) is the general international standard for hydraulic hoses.
This SAE Standard provides general, dimensional and performance specifications for the most common hoses used in hydraulic systems on mobile and stationary equipment.
Our hydraulic hose is qualified with the SAE certification. And the SAE standard numbers need to be printed on the surface of the hydraulic hose cover. So now let’s see what these SAE numbers mean for hydraulic hose.
Let’s start it now!
A hydraulic hose is designed with 3 layers, inner tube, reinforcement layer, and outer cover.
Inner Tube: Oil-resistant synthetic rubber inner tube
Reinforcement: Braided or spiral reinforcement, made of steel wire or textile
Outer Cover: Oil and weather-resistant synthetic rubber outer cover.
Type A:
Inner Tube: Oil-resistant synthetic rubber inner tube
Reinforcement: Single layer braided wire reinforcement, is made of one layer of braided steel wire, with high strength.
Outer Cover: Oil and weather-resistant synthetic rubber outer cover.
Here is a layer of adhesive rubber material between the reinforced steel wire and inner tube & outer cover, to add strength and stability to the whole hydraulic hose.
Type AT: The structure of this hydraulic hose is the same as the Type A SAE 100R1 hydraulic hose, but without needing to skive the cover when assembling, because of the special size of the outer cover design.
Type A:
Inner Tube: Oil resistant synthetic rubber inner tube
Reinforcement: Double layers of braided steel wire reinforcement
Outer Cover: Oil and weather resistant synthetic rubber outer cover.
Here is a layer of adhesive rubber material between the reinforced steel wire and inner tube & outer cover, to add strength and stability to the whole hydraulic hose.
Type AT: The structure of this hydraulic hose is the same as the Type A SAE 100R2 hydraulic hose, but without needing to skive the cover when assembling, because of the special size of the outer cover design.
The big difference between SAE 100R1 and SAE 100R2 is the layer of the steel wire reinforcement, and SAE 100R2 is structured with 2-wire braided steel wire reinforcement, so it can be much stronger.
The structure of the SAE 100R3 hydraulic hose is that:

SAE 100R17 has smaller bend radius, constant working pressure of 21MPa
SAE (Society of Automotive Engineers) has established a series of standards for hydraulic hoses, defining their specifications and performance requirements. The most commonly used standard for hydraulic hoses is SAE 100R. This standard covers a wide range of hose applications, including general-purpose, high-pressure, wire braid reinforced, and textile braid reinforced hoses.
For more specific information, you can refer to the following SAE standards:
Each standard specifies factors such as pressure rating, temperature range, fluid compatibility, fittings, bend radius, burst pressure, reinforcement, and markings. By adhering to SAE standards, manufacturers and users can ensure the safety, reliability, and compatibility of their hydraulic systems.
ISO (International Organization for Standardization) also has standards for hydraulic hoses, which are often used in conjunction with SAE standards. One of the most common ISO standards for hydraulic hoses is ISO 6178.
ISO 6178 provides a classification system for hydraulic hoses, based on their pressure rating, temperature range, and fluid compatibility. This standard helps to ensure that hoses are selected and used appropriately for their intended applications.
Other ISO standards related to hydraulic hoses include:
While SAE standards are widely used in North America, ISO standards are more commonly used in Europe and other parts of the world. In many cases, hydraulic hoses are required to meet both SAE and ISO standards to ensure global compatibility.
SAE (Society of Automotive Engineers) hydraulic fittings are connectors used to join hydraulic hoses to hydraulic components, such as pumps, valves, and cylinders. These fittings ensure a secure and leak-free connection, allowing hydraulic fluid to flow smoothly through the system.
SAE fittings are typically made of metal, such as steel or brass, and are available in a variety of styles and sizes to accommodate different hose diameters and pressure requirements. Common types of SAE hydraulic fittings include:
SAE fittings are essential components in hydraulic systems, and their proper selection and installation are critical for ensuring the system’s safety, reliability, and performance.
R1 and R2 are two common types of hydraulic hoses specified by SAE (Society of Automotive Engineers). They differ primarily in their pressure rating and intended applications.
SAE 100R1 is a general-purpose hydraulic hose with a lower pressure rating. It is suitable for a wide range of applications, including those involving moderate pressures and temperatures.
SAE 100R2 is a high-pressure hydraulic hose with a higher pressure rating than SAE 100R1. It is designed for more demanding applications, such as heavy-duty machinery and industrial equipment.
Key Differences:
| Feature | SAE 100R1 | SAE 100R2 |
|---|---|---|
| Pressure Rating | Lower | Higher |
| Applications | General-purpose | High-pressure |
| Reinforcement | Typically wire braid | Typically wire braid or textile braid |
In summary, SAE 100R1 is a good choice for most hydraulic applications, while SAE 100R2 is better suited for high-pressure applications. The specific hose type you should use will depend on the requirements of your particular application.
SAE 100R16 and SAE 100R17 are both high-pressure hydraulic hoses, but they differ in their reinforcement material and intended applications.
SAE 100R16 is a wire braid reinforced hose, providing enhanced strength and durability. It is suitable for a wide range of high-pressure applications, including those involving heavy-duty machinery and industrial equipment.
SAE 100R17 is a textile braid reinforced hose, offering flexibility and resistance to abrasion. It is particularly well-suited for applications where the hose needs to be bent frequently or is exposed to abrasive materials.
Key Differences:
| Feature | SAE 100R16 | SAE 100R17 |
|---|---|---|
| Reinforcement | Wire braid | Textile braid |
| Applications | General high-pressure applications | Applications requiring flexibility and abrasion resistance |
SAE 100R16 is a good choice for high-pressure applications where strength and durability are paramount, while SAE 100R17 is better suited for applications where flexibility and abrasion resistance are important. The specific hose type you should use will depend on the requirements of your particular application.
