Buyers sourcing hydraulic hoses from China frequently encounter both SAE and DIN/EN standards. Understanding the difference helps avoid costly mistakes.
SAE J517 (American Standard)
SAE 100R1AT, 100R2AT, 100R12, 100R13, 100R15 are common American hose specifications. They define construction, pressure and dimensions for hydraulic hoses.
EN 853 / 856 (European Standard)
EN 853 1SN/2SN are equivalent to SAE 100R1AT/R2AT (single and two wire braid). EN 856 4SP/4SH are four-spiral hoses for very high pressure - more common in European mining and heavy equipment.
Cross Reference Table
| SAE | EN | Construction |
|---|---|---|
| 100R1AT | 853 1SN | 1 wire braid |
| 100R2AT | 853 2SN | 2 wire braid |
| 100R12 | 856 4SP | 4 wire spiral |
| - | 856 4SH | 4 wire spiral (heavy) |
Why It Matters for Buyers
Most global OEMs accept either standard. However, fitting compatibility and bend radius can differ slightly. Always specify BOTH the standard and the size when ordering to avoid ambiguity.
