SAE100 R2AT is a high-pressure hydraulic hose with a synthetic-rubber tube and two braided steel-wire reinforcement layers. Buyers commonly consider it for hydraulic circuits on mobile and industrial equipment, but the correct choice depends on hose size, working pressure, fluid, temperature, routing, and fittings. Many product specifications list a temperature range of approximately -40°C to +100°C; confirm the exact limits and fluid compatibility against the manufacturer’s datasheet before ordering. This guide explains what to verify so you can assess SAE100 R2AT for your application and request a comparable supplier quotation.

SAE100 R2AT is a hydraulic hose designation associated with SAE J517. Its typical construction consists of an oil-resistant synthetic-rubber inner tube, two braided steel-wire reinforcement layers, and a rubber outer cover. The reinforcement helps the hose contain hydraulic pressure, while the tube and cover are selected for contact with the specified fluid and operating environment.
The designation alone does not define every detail of a particular product. Hose dimensions, working pressure, minimum bend radius, cover properties, and approved fluid range can vary by size and manufacturer. Buyers should compare the product datasheet with the equipment requirements rather than relying only on the “R2AT” marking.
Confirm the nominal inside diameter and the rated working pressure for that exact size. A hose’s pressure rating is not interchangeable across sizes, and the working pressure should not be confused with burst pressure. The full assembly—including hose, fittings, and installation—must be suitable for the system’s maximum operating conditions and applicable safety requirements.
R2AT’s two-wire-braid construction is a useful identification point, but it is not a substitute for pressure data. Ask the supplier for the relevant size-specific values and for confirmation that the proposed hose meets the required standard. If the equipment manufacturer specifies a different hose type or performance level, use that requirement as the starting point.
Some SAE100 R2AT products are specified for service between approximately -40°C and +100°C. These are commonly stated product limits, not a guarantee that every hydraulic fluid or operating condition is suitable throughout that range. Fluid type, exposure duration, ambient conditions, and pressure can all affect service suitability.
Identify the hydraulic fluid by name or chemistry and share it with the supplier. If the system uses a special fluid, elevated temperatures, or conditions outside the supplier’s stated limits, request written compatibility guidance before purchase. Do not assume that a hose suitable for petroleum-based hydraulic oil is automatically appropriate for every water-based, synthetic, or biodegradable fluid.
Check whether the outer cover is appropriate for the installation environment, including exposure to abrasion, weather, oil, heat, or chemicals. Verify the minimum bend radius and ensure the hose can be routed without kinking, twisting, or being pulled taut. Tight bends and torsion can place avoidable stress on a hose assembly.
Specify fitting type, thread standard, orientation, and assembly length, including how length is measured. A correct hose with incompatible fittings will not solve a connection problem. For replacement work, provide clear photographs and the equipment or fitting reference where available, but confirm all critical dimensions before production.
SAE100 R2AT is commonly evaluated for hydraulic lines in construction, agricultural, material-handling, and industrial machinery. Typical uses include pressure lines and other hydraulic circuits where the equipment design calls for a two-wire-braid hose. Suitability depends on the actual pressure, fluid, temperature, routing, and duty cycle—not simply on the industry or machine category.

For frequent movement, vibration, or tight routing, review the specified bend radius and assembly arrangement carefully. For harsh external exposure, compare cover options and protection needs. When pressure, temperature, or impulse demands exceed the selected R2AT product’s published limits, discuss another hose type with the equipment or hose supplier instead of making an unsupported substitution.
Before requesting offers, gather the system’s maximum working pressure, fluid, expected temperature range, hose inside diameter, and installation conditions. Include pressure surges or frequent cycling if these are relevant to the equipment. If you do not have a value, mark it as unknown rather than estimating it.
Document the overall length, end connections, thread standards, fitting angles, and orientation. Note the required quantity and whether the hose will be supplied as bulk hose or a finished assembly. For replacement orders, a drawing or sample can help clarify the configuration, but it should not replace dimensional confirmation.
Request a datasheet that identifies the hose type and size, working pressure, temperature limits, bend radius, and relevant construction details. Check that quotations describe the same size, fittings, length, and delivery scope before comparing price. Ask how the supplier identifies products and handles inspection or traceability if these are requirements for your purchasing process.
Ask each supplier to state its minimum order quantity, production or dispatch lead time, packaging, shipping terms, and quotation validity. These details can vary by size, order volume, customization, and current production schedule, so they should be confirmed for the specific inquiry. Clarify whether any stated lead time includes fittings, assembly, inspection, and export preparation.
At Hengshui Xinchi Hose Manufacturing Co., Ltd., we support B2B buyers evaluating hydraulic rubber hoses, including SAE100 R2AT options. To help us review your requirement, share the hose size, working pressure, fluid, temperature range, hose length, fitting details, quantity, and delivery destination. We can then discuss the applicable product information and the details that need confirmation before a purchase decision.
For repeat or customized requirements, provide the same specification format across each requested size or assembly. This makes it easier to compare quotations and identify differences in construction, connections, and commercial terms. Where an operating limit or compatibility question is not established by the available product information, request clarification before approving the hose for service.
SAE100 R2AT is a two-wire-braid hydraulic hose that may suit applications whose pressure, size, fluid, temperature, and routing requirements match the specific product datasheet. Start by confirming the system requirements, then verify the size-specific working pressure, temperature and fluid limits, bend radius, and fittings. Avoid selecting by hose designation or price alone.
Your next step is to prepare a complete specification and request a written quotation with product details, MOQ, lead time, and delivery terms. Hengshui Xinchi Hose Manufacturing Co., Ltd. welcomes B2B inquiries for SAE100 R2AT hydraulic hoses; send your application and assembly requirements so we can discuss a suitable option for evaluation.
