SAE100 R2AT is a two-wire-braid hydraulic hose designed to carry hydraulic fluids in equipment operating under pressure. Its construction generally includes an oil-resistant inner tube, two braided steel-wire reinforcement layers, and a protective outer cover. It is commonly considered for mobile and industrial hydraulic circuits, but the correct hose must be selected by matching its size, working-pressure rating, temperature limits, fluid compatibility, and installation conditions to the application.
This guide explains the hose’s construction, the specifications buyers should verify, and how to assess supplier offers. At Hengshui Xinchi Hose Manufacturing Co., Ltd., we support B2B buyers seeking hydraulic rubber hose supply and can discuss requirements such as size, quantity, application, and documentation before a quotation is prepared.
This guide is intended for hydraulic equipment manufacturers, maintenance teams, distributors, and procurement professionals evaluating hose for a new or replacement application. It can help organize a technical inquiry, but it is not a substitute for equipment-manufacturer requirements or a qualified engineering review. If a hose is used in a safety-critical or regulated system, confirm the design and installation requirements with the responsible technical authority.
SAE100 R2AT is a hydraulic hose designation associated with a hose construction featuring two braided steel-wire reinforcement layers. The reinforcement helps the hose contain internal pressure, while the inner tube is selected to suit hydraulic fluid and the outer cover helps protect the assembly from its surrounding environment. The exact compound, dimensions, and performance limits should be confirmed from the manufacturer’s product specification.
The “R2” designation is commonly used to identify a two-wire-braid hose type, while “AT” indicates a covered hose form in the designation. Buyers should not rely on the name alone to establish suitability: published performance, test requirements, and dimensional details must be checked against the applicable SAE J517 edition and the supplier’s declared product data. A hose that looks similar may differ in construction or rating.
Typical product descriptions identify a synthetic-rubber inner tube, two layers of high-tensile steel-wire braid, and a rubber outer cover. Exact rubber formulations and cover options vary by manufacturer, so request confirmation if the hose will encounter abrasion, weather, oil, ozone, or other demanding conditions. Special requirements should be stated before production or quotation rather than assumed from a generic product name.
Some product literature gives a typical operating-temperature range of approximately -40°C to +100°C for SAE100 R2AT hose. This is a general reference, not a guarantee for every fluid, construction, or operating condition; the permitted range must be confirmed for the offered product and application. Temperature exposure can also affect hose life, particularly when pressure, bending, or external heat is present.
Before comparing offers, review the specification as a complete set rather than focusing only on the hose designation. At minimum, confirm the nominal size, working-pressure rating, burst-pressure information where required, minimum bend radius, temperature range, fluid compatibility, and dimensional tolerances. Also clarify whether the requirement is for bulk hose or a finished hose assembly with fittings.
| Specification | What to Confirm | Why It Matters |
|---|---|---|
| Nominal size and inside diameter | Required dash size or measured connection requirements | Affects flow, connection fit, and system compatibility |
| Working pressure | Supplier rating for the exact hose size and construction | Must meet or exceed the equipment requirement under the specified conditions |
| Minimum bend radius | Published value for the selected size | Helps prevent a routing plan from bending the hose too tightly |
| Temperature and fluid | Approved range and compatibility for the actual medium | Limits depend on material and service conditions |
| Fittings and assembly | End type, thread, orientation, and assembly requirements | Reduces mismatch during installation and procurement |
For example, a nominal DN 6 (1/4-inch) hose size identifies a size category, not a universal pressure rating. Pressure capability and bend-radius values are size- and product-specific; obtain them from the current datasheet for the exact item. Do not infer a rating from another diameter or from a supplier’s description of a different hose standard.
SAE100 R2AT hoses are used in hydraulic circuits on equipment such as construction machinery, agricultural machinery, industrial equipment, and material-handling systems. These are application categories, not blanket approvals: suitability depends on the machine maker’s requirements, system pressure, fluid, routing, and operating environment. The hose should be selected as part of the complete hydraulic assembly.
With competitive price and timely delivery, Hengshui Xinchi Hose Manufacturing Co., Ltd. sincerely hope to be your supplier and partner.
Start with the equipment documentation and identify the required hose standard, nominal size, and pressure rating. Next, verify fluid type and temperature, then assess external exposure such as abrasion, weather, heat, and contact with nearby components. Finally, review routing and movement, including bend radius and the hose’s behavior during machine operation.
For a replacement, record the existing hose markings and assembly details, but do not treat them as the only source of truth. A previous installation may not reflect the original design requirement, and markings can be incomplete or difficult to read. Where possible, confirm the specification against the equipment manufacturer’s parts information or engineering documentation.
A clear inquiry helps a supplier determine whether the requested product matches the application and prepare a more useful quotation. Share the required standard, nominal size, quantity, intended use, fluid, temperature range, and working-pressure requirement. For assemblies, add hose length in mm, fitting type, thread details, orientation, and any packaging or labeling requirements.
When reviewing a quotation, compare like with like: identical hose size, construction, rating, fitting details, quantity basis, and delivery terms. Ask which technical documents are available and whether the quoted item’s datasheet corresponds to the precise product being offered. If a requirement is not stated, request written clarification before approving an order.
Pricing for SAE100 R2AT hose can depend on size, order quantity, construction details, packaging, and whether fittings or assembly work are included. Minimum order quantities and production or shipping lead times also vary by supplier, item, and order schedule. Because these factors are order-specific, buyers should request a current quotation rather than rely on a general market estimate.
For a more accurate commercial response, provide target quantity, delivery location, preferred packing, and any required inspection or documentation. If your project has a required delivery date, mention it when requesting the quote and ask the supplier to confirm the schedule in writing. Avoid treating an indicative lead time as a confirmed commitment until the order details and availability are agreed.
Evaluate suppliers on product fit and communication, not price alone. Confirm that the supplier can identify the offered hose’s construction and provide applicable technical information for the requested size. For assemblies, check how fitting compatibility and assembly details will be verified.
At Hengshui Xinchi Hose Manufacturing Co., Ltd., we supply hydraulic rubber hose products for B2B customers and welcome inquiries for SAE100 R2AT requirements. To help us assess your request, send the hose size, quantity, application, operating conditions, and whether you need bulk hose or an assembly. We can then discuss product specifications, available documentation, commercial terms, and the information needed to move toward an order.
SAE100 R2AT is a two-wire-braid hydraulic hose type used in a range of mobile and industrial hydraulic applications, but the designation alone does not confirm that a particular product is right for your system. Verify the exact size, pressure rating, bend radius, temperature limits, fluid compatibility, and fitting requirements against the application and supplier data. This is the most reliable way to avoid specification gaps and sourcing mismatches.
Your next step is to gather the equipment requirements and send a complete inquiry to a qualified supplier. Include quantity, delivery destination, and documentation needs so the supplier can respond on technical and commercial details together.
