SAE100 R2AT can be a good choice for high-pressure mobile hydraulic equipment when the circuit needs a flexible, two-wire-braid hose and the hose’s published working-pressure rating matches the system’s operating and peak pressures. Its construction is commonly used in hydraulic lines on equipment such as excavators, loaders, agricultural machinery, and mobile service vehicles. The right choice depends on hose size, pressure, temperature, fluid compatibility, routing, and movement—not on the pressure label alone. At Hengshui Xinchi Hose Manufacturing Co., Ltd., we recommend confirming these details against the specification for the exact hose and assembled line before ordering.

SAE100 R2AT is a hydraulic hose designation associated with a two-wire-braid reinforcement construction. The reinforcement helps the hose contain hydraulic pressure, while the inner tube carries the fluid and the outer cover helps protect the assembly from its working environment. Exact materials and performance values should be confirmed from the product documentation supplied for the hose being purchased.
For mobile equipment, the value of this construction is its potential fit in flexible pressure lines that move with cylinders, booms, steering systems, or other working components. A hose can still fail prematurely if it is selected only by its general type. Correct bore, pressure rating, temperature range, fluid compatibility, assembly, and routing all affect whether it is suitable for a particular circuit.
Mobile machinery often has moving assemblies and compact hose routes, so flexibility can be important for connecting pumps, valves, cylinders, and motors. SAE100 R2AT may be appropriate where the hose must accommodate normal equipment movement and the specified bend radius can be maintained. The hose should not be forced into a tighter curve than its product data allows, because sharp bends can put extra stress on the reinforcement and connections.
Compare the hose’s published working-pressure rating with the circuit’s normal operating pressure and pressure peaks. Do not treat a burst-pressure figure as an acceptable operating pressure; use the manufacturer’s working-pressure data for the exact hose size. If the equipment has frequent pressure spikes, confirm the expected impulse duty with the hose supplier or equipment designer.
For example, if a machine’s operating pressure is 180 bar, that number is only an input for selection—not proof that any SAE100 R2AT hose is suitable. The selected hose must have a documented working-pressure rating that covers the circuit’s requirements, including relevant peaks and operating conditions. If reliable pressure data is unavailable, obtain it from the machine manufacturer or measure the circuit using an appropriate method before specifying the hose.
Hydraulic fluid type and operating temperature should fall within the hose manufacturer’s stated compatibility range. The outer cover also needs to suit the equipment’s exposure to abrasion, oils, weather, and other site conditions. A standard cover may not be the best choice where hoses regularly rub against metal edges or face severe external wear; protective sleeves, guards, rerouting, or a different hose option may be needed.
| Selection factor | What to confirm | Why it matters |
|---|---|---|
| Hose size | Inside diameter and end-connection dimensions | Affects flow, fit, and connection compatibility. |
| Pressure | Published working pressure for the exact size, plus circuit peaks | Prevents selection based on a general designation rather than the actual rating. |
| Temperature and fluid | Operating range and compatibility in the product documentation | Heat or incompatible fluid can reduce service suitability. |
| Routing and movement | Minimum bend radius, movement, and potential twist | Improper installation can add stress and cause damage. |
| Assembly | Fitting type, crimp specification, and assembly instructions | A hose is only one part of a pressure-bearing assembly. |
Use actual measurements and equipment documentation rather than estimating from a similar machine. As an illustration, a routing plan that has only 150 mm of clearance for a bend must be checked against the specific hose’s minimum bend radius and the fitting arrangement. This 150 mm figure is an example of a measurement to verify, not a general SAE100 R2AT specification.

SAE100 R2AT is not automatically suitable for every high-pressure mobile application. It may be a poor fit if the required working pressure exceeds the rating for the chosen size, if the temperature or fluid is outside the documented limits, or if the hose cannot be routed within its permitted bend radius. Similarly, severe abrasion, repeated flexing, or demanding pressure impulses may call for a different hose design or additional protection.
Do not select an alternative solely because it appears heavier or has a higher nominal pressure description. Compare the applicable product standards, manufacturer ratings, size, impulse requirements, and installation conditions. Where duty is severe or uncertain, ask the equipment manufacturer or hose supplier to review the circuit requirements before replacing or specifying a hose.
This process also helps buyers compare quotations consistently. Ask suppliers to identify the hose size, applicable specification, working-pressure data, temperature and fluid limitations, fitting details, and any assembly requirements. A quotation that names only a hose family may not provide enough information to confirm application fit.
At Hengshui Xinchi Hose Manufacturing Co., Ltd., we work with buyers evaluating hydraulic hose options for equipment and industrial applications. To help us assess whether SAE100 R2AT may fit your requirement, share the hose size, required length, operating and peak pressure, fluid, temperature range, fittings, and installation conditions. We can use those details to discuss product options and provide the relevant product information available for review.
For replacement orders, a sample hose or clear photographs of the markings and fittings can help identify the existing configuration, but they do not replace a pressure and application check. Confirm critical dimensions and operating requirements with your equipment documentation before production or installation. For safety, hydraulic hose assemblies should be selected and installed by qualified personnel, and damaged assemblies should be handled according to site procedures.
SAE100 R2AT is a better option when your mobile hydraulic circuit needs a flexible, two-wire-braid hose and the exact product’s documented ratings and compatibility match the equipment’s pressure, temperature, fluid, routing, and duty. It is not the right choice merely because the machine is described as high-pressure or because an existing hose looks similar. Verify the full hose assembly against real operating data, including pressure peaks and installation limits.
Your next step is to prepare the circuit details and compare them with the supplier’s documentation for the proposed hose size and fittings. If you are sourcing SAE100 R2AT for mobile equipment, contact Hengshui Xinchi Hose Manufacturing Co., Ltd. with your application requirements to discuss suitable options and request product information before placing an order.
