SAE100 R1AT Hydraulic Hoses: Specifications, Applications, and Selection Guide

SAE100 R1AT is a single-wire-braid hydraulic hose designed to convey hydraulic fluids under pressure. Its typical construction combines an oil-resistant synthetic rubber tube, one braided steel-wire reinforcement layer, and a protective rubber cover. It is used in hydraulic systems where the hose’s rated pressure, temperature range, fluid compatibility, and bend radius match the equipment requirements. This guide explains what to check before specifying or sourcing it, while noting that exact limits vary by hose size and manufacturer.

Key Takeaways

• R1AT identifies a hose construction with one steel-wire braid; it is not a universal pressure rating.
• Working pressure, minimum bend radius, and dimensions must be checked for the selected nominal bore against the supplier’s product data.
• A commonly specified operating temperature range for this hose category is approximately -40°C to +100°C, but confirm the exact range for the hose and fluid in use.
• Share the application, operating conditions, hose length, and end-fitting details when requesting a quotation.

Who This Guide Is For

This guide is intended for hydraulic equipment manufacturers, maintenance teams, distributors, and procurement professionals comparing hose options. It can help buyers prepare a technical specification and identify questions for a hose supplier. It is not a substitute for the equipment manufacturer’s requirements or a product-specific datasheet. Always verify the hose and assembly are suitable for the actual system.

SAE100 R1AT Construction and Basic Specifications

What the R1AT Designation Means

SAE100 R1AT is a hydraulic hose designation associated with a single steel-wire braid reinforcement. The “R1” construction indicates one wire braid, while “AT” is used in the designation for this hose type. The inner tube is generally made from oil-resistant synthetic rubber, and the cover is typically a synthetic rubber compound selected to protect against external conditions. The exact compound, dimensions, and performance limits should be confirmed from the specific manufacturer’s documentation.

The steel braid helps the hose withstand internal pressure, while the rubber tube provides the fluid-contact surface and the cover protects the reinforcement. These layers work together, so a hose should not be selected by construction name alone. A correctly chosen hose must also suit the fluid, pressure cycles, temperature, routing, and connection hardware. A complete hose assembly should be evaluated as a system, not just as a length of hose.

Specifications Buyers Should Confirm

A commonly stated temperature range for R1AT-category products is approximately -40°C to +100°C. Treat this as a point to verify rather than a guarantee for every product, fluid, or operating condition. Likewise, the hose’s working pressure is size-specific; do not assume that a single pressure value applies to every nominal bore. Request the supplier’s current technical data for the exact item under consideration.

Applications and Application Matching

R1AT hoses are considered for hydraulic lines in mobile and stationary equipment when the system design calls for a single-wire-braid hose and the product ratings meet operating requirements. Potential applications include machinery, agricultural equipment, material-handling systems, and general industrial hydraulic circuits. Actual suitability depends on pressure, temperature, movement, environment, and the equipment manufacturer’s specifications. The application name alone is not enough to establish compatibility.

Match the Hose to Its Operating Conditions

Start with the fluid and its operating temperature, then identify the system’s normal and peak pressures. Account for pressure surges and repeated cycling where the equipment design requires it, rather than selecting only against a nominal reading. Next, check how the hose will be routed, including movement, vibration, abrasion exposure, and proximity to heat sources. If these conditions exceed the intended use of a standard cover or construction, ask the supplier about an appropriate alternative.

Nominal bore also deserves careful attention. In common SAE dash sizing, -06 corresponds to a nominal bore of 3/8 inch, and -08 corresponds to 1/2 inch. Confirm the size convention and actual product dimensions on the datasheet, because nominal size is not a complete description of the hose assembly. If the hose is too small for the required flow, pressure loss and heat generation may become concerns; final sizing should follow the system design.

Selection Framework for B2B Buyers

Step 1: Define the Technical Requirements

Record the hose size, required length, fluid type, operating temperature, and system pressure. Include any known pressure pulses, equipment movement, or environmental exposure. If you are replacing an existing hose, note its markings and measure the assembly carefully, but do not rely on visual similarity as proof of equivalence. Compare the replacement against the original equipment requirements and the new supplier’s data.

Step 2: Confirm Assembly and Routing Details

Specify fitting style, connection size, orientation, and any required end configuration. Check the installed route for adequate clearance and compliance with the hose’s minimum bend radius. Avoid twisting the hose during installation, and consider whether clamps or guards are needed to manage movement or abrasion. Where routing details are uncertain, provide a drawing or clear photographs for review.

Step 3: Review the Datasheet and Order Scope

Ask for product-specific ratings and dimensional information for the exact size and construction. Confirm what is included in the quotation: hose only or assembled hose, fitting details, inspection documents, packaging, and shipping terms. If a buyer requires traceability or documentation, state those requirements before ordering and confirm availability in writing. Do not assume that a general product description covers every project requirement.

Pricing, MOQ, and Lead-Time Considerations

Pricing can depend on hose size, requested length, construction and cover options, fitting requirements, order quantity, and destination. Minimum order quantities and lead times are supplier- and order-specific, so they should be confirmed during quotation rather than inferred from a catalogue listing. For a fair comparison, send the same technical specification to each supplier and compare the full delivered scope. A lower unit price may not represent equivalent materials, fittings, documentation, or delivery terms.

Supplier Evaluation Checklist

• Can the supplier provide product-specific specifications for the requested size?
• Are working pressure, temperature limits, dimensions, and bend radius clearly stated?
• Can the supplier confirm fluid compatibility and fitting options for the application?
• Are quotation scope, MOQ, lead time, packaging, and shipping terms transparent?
• Can any required documentation or identification be confirmed before order placement?

When evaluating Hengshui Xinchi Hose Manufacturing Co., Ltd., buyers can share their required size, operating conditions, quantity, and connection details to discuss a suitable supply option. We recommend reviewing the proposed product information against the equipment specification before confirming an order. For repeat purchasing, align the approved item description and assembly details with your internal purchasing records. Clear requirements help reduce avoidable differences between quotation, production, and installation.

Conclusion: How to Choose SAE100 R1AT

SAE100 R1AT is a single-steel-wire-braid hydraulic hose option, but the designation alone does not establish that it fits a particular system. Choose it only after confirming size-specific pressure and dimensional data, temperature and fluid compatibility, bend radius, routing conditions, and fitting requirements. Treat typical figures, including the commonly cited -40°C to +100°C temperature range, as items to verify on the exact product datasheet. The practical next step is to prepare your application specification and request a product-specific quotation and technical review from your hose supplier.
