This technical data sheet is a reference guide to the properties of this product type; it is not a quality certificate for the product you are buying. The measurements, dimensions and physical or geometric characteristics of the product supplied may vary by manufacturer, heat and lot, and may even fall outside the cited standards. If any of these figures is critical to your design or build, verify it with one of our advisors against the physical product or the lot's mill certificate, so you can be fully certain of what you are buying. · Original data sheet: tectul.com/en/conduccion-de-fluidos/mangueras/ficha-tecnica-manguera-sae-100-r1-at.html
The bar values in this table and the rest of this sheet are calculated from the manufacturer's psi figure using the exact conversion 1 psi = 0.0689476 bar. This is necessary because the bar column of this reference's original sheet has a row error at the 1″ diameter (it prints 43.1 bar, which actually belongs to the 1-1/4″ row, instead of the ≈68.9 bar corresponding to 1000 psi); the psi value on that row (1000 psi) is consistent with the rest of the table's progression and is taken as the verified figure.

The 5/16″ row of this standard reference's manufacturer sheet lists 265 psi working pressure, a value that breaks the table's decreasing progression (3150, 2880, 265, 2355…) and most likely drops a digit (a value near 2650 psi would be expected). It is not corrected because it cannot be verified with certainty: for that specific diameter, the real working pressure is confirmed on quotation.

2. Selection criteria and safety factor
What the 1:4 working-to-burst pressure ratio means
Working pressure (W/P) is the manufacturer's maximum continuous-use limit; burst pressure (B/P) is the pressure at which the hose fails in a destructive laboratory test, never an operating value. In this SAE 100R1/100R1AT family the ratio is 1:4 across all twelve sizes of both references: the 3/16″ works at 3000 psi (206.8 bar) and bursts in testing at 12000 psi (827.4 bar); the 2″ works at 375 psi (25.9 bar) and bursts at 1600 psi (110.3 bar). That 4:1 margin is the family's minimum design margin and must not be read as available service reserve: never operate above the tabulated W/P, whether continuously or during pressure spikes.
When to use R1/R1AT versus R2, R5 or R6
The single braided steel wire layer of the R1/R1AT family is the entry-level construction of the SAE 100 high-pressure line: it covers the same dimensional range as double-braid R2, but at roughly half the working pressure (for example, 2000 psi/137.9 bar at 1/2″ R1 AT versus 3500 psi/241.3 bar at 1/2″ R2 AT, see data sheet FT-TC-MAN-HIDR-R2-001). Specify R1/R1AT when the circuit's design pressure stays within that limit and a lighter hose with a smaller bend radius than double-braid is preferred. When design pressure exceeds R1's range, move up to R2/R2AT — do not push R1 above its tabulated W/P. For return, pilot or low-pressure lubrication lines where weight and bend radius matter more than maximum pressure, the textile-reinforced R5 (data sheet FT-TC-MAN-HIDR-R5-001) or R6 (data sheet FT-TC-MAN-HIDR-R6-001) families are lighter and cheaper per meter.
Why two references of the same type exist
The real, verifiable difference between R1 AT and standard R1 in this sheet is the maximum temperature declared by each manufacturer (100 °C versus 121 °C) and the tube/cover compound (nitrile versus generic synthetic rubber); working and burst pressures for both are of the same order of magnitude at each diameter. The "AT" designation in the hose market usually indicates an elevated-temperature service variant; in the manufacturer sheets available for this group, it is the standard reference (without AT) that declares the higher thermal limit, so the choice between the two should be based on the actual fluid and line temperature, not on assuming "AT" always means the wider thermal range.
3. Construction and fluid compatibility
Inner tube: nitrile (R1 AT) versus synthetic rubber (standard R1)
The inner tube is the surface in permanent contact with the fluid and defines the hose's chemical compatibility. On the R1 AT reference it is nitrile (NBR), an industry-standard elastomer for hydraulic service due to its resistance to mineral oils and aliphatic hydrocarbons. On the standard R1 reference the manufacturer declares "high quality synthetic rubber" without specifying the exact elastomer; the exact grade and compound of this tube is confirmed on quotation.
Reinforcement: a single braided steel wire layer
Both references carry a single layer of high-tensile braided steel wire over the tube. This single braid sets the family's tabulated working pressure and distinguishes it from the double-braid R2/R2AT (data sheet FT-TC-MAN-HIDR-R2-001), which doubles the reinforcement to roughly double the pressure range at the same nominal diameter.
Compatible fluids
| Fluid | Compatibility |
|---|---|
| Mineral hydraulic oils | Compatible — the primary application declared by both manufacturers |
| Low-viscosity hydraulic fluids | Compatible — application declared on the R1 AT sheet |
| Synthetic fluids and aliphatic hydrocarbons | Compatible with nitrile tube (R1 AT); on standard R1 confirmed on quotation depending on the exact elastomer |
| HFD fire-resistant hydraulic fluids (phosphate ester based) | Not compatible — no elastomer in this sheet is declared suitable for HFD; requires a special tube (EPDM or other), outside the scope of this sheet |
Fittings and ends
This sheet covers bulk hose tube, sold by the 100 m roll on the R1 AT reference; it does not include fittings or the crimping process. Fitting type, thread or flange, and exact crimp diameter are selected per the destination equipment and confirmed on quotation.
4. Frequently asked questions
What is the difference between SAE 100R1 and SAE 100R1 AT hose?
Both are single braided steel wire hoses with the same dimensional range (3/16″–2″), but with different tube and cover: R1 AT is nitrile and its manufacturer declares -40 °C to +100 °C; standard R1 is generic synthetic rubber and its manufacturer declares a wider range, -40 °C to +121 °C. Working and burst pressures for both are of the same order at each diameter.
What pressure does the SAE 100R1 AT hose in 1/2″ work at?
2000 psi (137.9 bar) working pressure and 8000 psi (551.6 bar) test burst pressure, per the manufacturer sheet for the manguera-sae-100-r1-at reference.
Can I use an R1 hose instead of an R2 if I need more pressure?
No. R1/R1AT has a single reinforcement braid and its tabulated working pressure is roughly half that of double-braid R2/R2AT at the same nominal diameter. If the circuit requires more pressure than R1's tabulated W/P, the correct choice is to move up to the R2/R2AT reference (data sheet FT-TC-MAN-HIDR-R2-001), not to operate R1 above its limit.
What does this sheet's 1:4 (W/P:B/P) ratio mean?
It means the destructive laboratory-test burst pressure is four times the declared continuous working pressure: for example, 375 psi working and 1600 psi burst on the 2″ hose. It is the SAE 100R1/R1AT family's minimum design margin and must never be read as available operating pressure.
Which EN standard corresponds to SAE 100R1 hose?
EN 853:2026, type 1SN — the European designation for single braided steel wire hydraulic hoses, the constructive equivalent of the SAE 100R1/R1AT family.
Can I bend this hose permanently at its tabulated minimum radius?
The tabulated minimum bend radius (for example 69 mm at 3/16″, 635 mm at 2″ for R1 AT) is the limit below which the steel reinforcement suffers fatigue damage; in fixed installations a radius larger than the minimum is recommended to extend hose life, and tight bends near fittings should be avoided.
5. Application notes
Installation
Respect the tabulated minimum bend radius per diameter and avoid twisting during routing: twisting the hose reduces its service life and can loosen the fitting. Do not install straight runs under tension; leave slack for the line's thermal and vibration movement. Verify that the fitting and seal rating are compatible with the tabulated W/P of the chosen diameter before commissioning.
Storage
Store rolls horizontally on a flat surface, away from ozone sources (electric motors, welding) and direct sunlight, which degrade the tube and cover elastomer over time. Keep the ends capped to prevent moisture or debris from entering before fitting crimping.
Selection
Always select based on the circuit's actual maximum working pressure, never on burst pressure. If line temperature sustainedly exceeds 100 °C, verify the chosen reference's temperature curve with the real manufacturer before specifying, since this group's manufacturer sheets declare different limits for R1 AT and standard R1.
6. Technical notice and limitation of liability
The pressures, dimensions, weights and other characteristics in this sheet are theoretical calculation values obtained from nominal properties published in the standards cited (ASME B36.10-2022, ASME B31.3-2024, ASTM A106/A106M-19a, ASTM A53/A53M-24, API Spec 5L 46th ed.). They guide selection; they are not a certificate of conformity for any given lot.
The actual behavior of each lot varies with manufacturing — wall tolerance (up to −12.5%), out-of-roundness, residual stresses — and with the raw material — chemical composition within the ranges the standard allows, heat-to-heat differences. To certify a lot, the tests defined by its product standard are required: tensile test, flattening test and hydrostatic test, documented in the manufacturer's mill test certificate (MTC), which TECTUL supplies upon request; testing of the lot in an independent laboratory can also be arranged.
These values must not be used as the sole criterion in critical or safety applications, or wherever failure of the line may compromise people, property or the environment: in such cases the design belongs to the project's responsible engineer under the applicable code (ASME B31.3, B31.1 or the one governing the installation), with the design temperature, corrosion allowance and load cases of the actual service.
