SAE100 R1AT is a medium-pressure hydraulic hose type commonly specified for conveying hydraulic fluids in mobile and industrial equipment. It typically has an oil-resistant synthetic rubber tube, one high-tensile steel-wire braid reinforcement, and a protective rubber cover. The right size cannot be selected from the hose name alone: buyers should confirm the required inside diameter, working pressure, fluid and temperature compatibility, routing, and end fittings against the supplier’s current product data.
This guide explains the construction, size conventions, application considerations, and purchasing checks that help B2B buyers assess SAE100 R1AT hose suitability. Product ranges and ratings can vary by manufacturer, so use the confirmed datasheet for the exact hose and assembly being quoted.
This guide is intended for hydraulic equipment manufacturers, maintenance teams, distributors, and procurement professionals evaluating SAE100 R1AT hose. It is useful when preparing a new hose specification, replacing an existing line, or comparing quotations from different suppliers. It is not a substitute for the equipment manufacturer’s requirements or the hose supplier’s technical documentation.
SAE100 R1AT hose is generally built around three functional layers. The inner tube is typically made from synthetic rubber selected for compatibility with the specified hydraulic fluid, the reinforcement is one braid of high-tensile steel wire, and the outer cover is rubber designed to protect the reinforcement from the service environment. The exact compounds, dimensions, and ratings should be verified for the specific manufacturer and product code.
The single wire braid provides reinforcement against internal pressure while allowing the hose to route through machinery. “AT” is commonly used to describe a hose cover suitable for applications where the hose passes through equipment or fittings designed for that cover style; confirm the required cover and fitting configuration before assembly. Do not assume that hoses with similar names have identical dimensions or performance ratings.
R1AT hoses are commonly considered for hydraulic circuits on construction, agricultural, material-handling, and industrial equipment. Typical examples include pressure lines between pumps, valves, and actuators, provided the hose’s rated pressure and other service limits meet the system requirements. Suitability depends on the complete operating conditions, including pressure peaks, temperature, fluid, motion, and external exposure.
Temperature limits are product-specific. Some R1AT product ranges publish a working temperature span around -40°C to +100°C for compatible petroleum-based hydraulic fluids, but that range must not be treated as universal or applied automatically to other fluids. Check the supplier’s stated limits for the hose, fluid, and assembly, especially when the system operates near either temperature extreme.
Hydraulic hose dash sizes are commonly expressed in sixteenths of an inch and refer to nominal inside diameter. They are a useful starting point for identifying a hose, but they do not replace confirmation of the actual dimensions and tolerances in the product data. The following examples show the usual nominal size convention.
| Dash Size | Common Nominal Inside Diameter | Buyer Check |
|---|---|---|
| -6 | 3/8 in | Confirm the actual bore and matching fittings. |
| -8 | 1/2 in | Check flow demand, pressure rating, and routing space. |
| -12 | 3/4 in | Verify line connections and required flow capacity. |
| -16 | 1 in | Confirm assembly dimensions and the system’s pressure requirement. |
These are nominal examples, not a guarantee that every supplier offers every size. A hose that is too small for the required flow can contribute to excessive pressure drop and heat, while an unnecessarily large hose may be harder to route and may require different connections. Ask the supplier for the available size range and dimensional data for the exact R1AT series.
Working pressure is one of the most important selection criteria, and it varies with hose size and product construction. Compare the system’s maximum operating pressure, including relevant pressure surges, with the hose’s published rating for that size. Also check the rated minimum bend radius, because bending tighter than the manufacturer’s stated limit can compromise hose performance.

Confirm the recommended temperature range, compatible fluids, outside diameter, and cover characteristics. For fluid compatibility, identify the actual fluid type and any additives rather than relying only on a broad label such as “hydraulic oil.” For the assembly, verify the end connection type, thread standard, orientation, and crimping requirements with the hose and fitting supplier.
Record the normal and maximum system pressure, fluid type, operating temperature, and environmental exposure. Include pressure spikes or repeated load changes where these are part of the machine’s duty cycle. If the application includes abrasion, weather, oil contact, or tight equipment spaces, describe those conditions when requesting a recommendation.
Use the equipment specification or existing assembly details to identify the nominal bore and connection sizes. Check that the hose can follow the intended route without twisting, stretching, or exceeding its minimum bend radius. Consider movement during operation, nearby heat sources, and possible contact with sharp edges or moving components.
Compare the hose’s published size-specific working pressure with the system requirement, not with a rating from another size or series. Confirm that the tube material is suitable for the fluid and that the complete assembly can operate within the stated temperature range. Where the conditions are uncertain or severe, provide the supplier with the application details before finalizing the specification.
A hose assembly is only as suitable as its hose, fittings, and installation. Provide fitting type, thread, angle or orientation, finished length, and any protective covering requirements. If replacing a hose, use the original part information where available, but verify that it remains appropriate for the current system conditions.
Quotation terms depend on hose size, requested length, fittings, order quantity, packaging, and whether the buyer needs hose only or finished assemblies. Minimum order quantities and lead times are supplier- and order-specific, so they should be confirmed in the quotation rather than assumed from a general product listing. For repeat purchasing, sharing an itemized specification can help reduce ambiguity between orders.
For a comparable quotation, send the required dash size, quantity, hose or assembly requirement, working conditions, fitting details, destination, and target delivery schedule. If you are still evaluating the product, ask for the current datasheet and available documentation before placing a production order. Buyers should confirm any requested inspection or documentation requirements at the quotation stage.
Hengshui Xinchi Hose Manufacturing Co., Ltd. supplies rubber hose products, including hydraulic hose options for B2B buyers. When requesting SAE100 R1AT hose, share your application and purchasing requirements so our team can confirm the available product details, sizes, and supply terms for your inquiry. Technical suitability should always be established from the product information and conditions applicable to the specific order.
SAE100 R1AT is generally a one-wire-braid hydraulic hose type used in medium-pressure applications, but the designation alone does not establish that a particular hose is suitable for your equipment. Start with the required bore and fittings, then verify size-specific pressure, fluid compatibility, temperature limits, bend radius, and routing conditions using the supplier’s data. These checks help you compare products on a consistent basis and reduce avoidable specification mismatches.
Before requesting a quotation, prepare your hose size, operating conditions, assembly details, order quantity, and delivery destination. Contact Hengshui Xinchi Hose Manufacturing Co., Ltd. with this information to discuss available options and confirm the relevant technical and commercial details. If a specification is uncertain, resolve it with your equipment requirements and the supplier’s documentation before ordering.
