Hydraulic hose ULTIMATE 1SN Blue - DN5-DN76

ULTIMATE 1SN Blue is a single wire braid hydraulic hose with increased thermal resistance - intended for medium and low pressure hydraulic systems in industry, compressors and mining, where operating temperatures do not exceed +150°C. The blue colour version offers all the same technical parameters as the standard version, but with a distinctive outer cover - making it easier to identify installations and visually distinguish hydraulic circuits. Construction: one high-strength steel wire braid, special synthetic rubber resistant to high-temperature hydraulic oils. The ULTIMATE line from a Polish manufacturer is a flagship product compliant with DIN EN 853 1SN, TS 6387, SAE 100 R1 AT/ATS, ISO 1436:2009, ISO 6805, EN 13463-1, EN 1804-3 and ISO 1307.

Applications

The ULTIMATE 1SN Blue hose is used in applications requiring increased thermal resistance: industrial compressors, hydraulic power units operating at high ambient temperatures, mining machinery, crimping machines, mine loaders, equipment requiring compliance with DIN EN 853 1SN. The temperature range of -50°C to +135°C (up to +150°C intermittently) allows operation in extreme conditions - from freezing climates to production halls and foundries. The single braid construction provides lightness and flexibility at moderate pressures (up to 250 bar in size DN5), which makes it ideal for control systems, low pressure supply lines and applications with small dynamic loads. The blue cover colour helps with visual identification of hydraulic circuits - useful in densely cabled industrial installations and during machine servicing.

Product selection

When selecting the size of the ULTIMATE 1SN Blue hose, three parameters are key: working pressure (WP), inside diameter (ID) and bend radius (R min). Smaller DN (DN5-DN10) withstand higher pressures (180-250 bar) and are used in control circuits and precision systems. Medium DN (DN13-DN25) cover most typical industrial applications (88-160 bar) - the standard choice for cylinders, crimping machines and power units. Large DN (DN32-DN76) are used to carry larger flows at lower pressures (35-63 bar) - typically in supply and return lines. The 4:1 safety factor (BP/WP) is standard for the 1SN standard and provides a margin for pressure pulses. The 1SN hose is LIGHTER and cheaper than 2SN (one braid instead of two) - choose 1SN when the application does not require high pressures. For pressures >300 bar or applications with pulses, consider the 2SN ULTIMATE version.

Compatibility

The ULTIMATE 1SN Blue hose is compatible with most mineral and synthetic hydraulic oils (phosphate esters - limited), water-glycol fluids (HFC), engine oils up to +150°C and pressurised water. Fittings are crimped onto standard BSP, JIC 37°, ORFS, METRIC and NPT clamps - the full list of compatible crimp fittings is available in the manufacturer catalogue. Certificates: PG (Russian Gosgortechnadzor - mining), ABS (American Bureau of Shipping - marine), ISO 9001 (quality). Compliance with DIN EN 853 1SN and SAE 100 R1 AT/ATS guarantees interchangeability while retaining the parameters of competing industrial brands. Additionally, compliance with EN 13463-1 (ATEX - explosive atmospheres) and EN 1804-3 (mining). The manufacturer runs a full hose assembly service based on ULTIMATE 1SN - with crimp fittings matched to the specific customer application.

The difference is the number of steel wire braids: 1SN has ONE braid, 2SN has TWO. This translates into working pressures: 1SN up to 250 bar (DN5), 2SN up to 415 bar (DN5). 1SN is LIGHTER, cheaper and more flexible - ideal for medium to low pressures. 2SN is for high pressures and more demanding applications. The choice depends on the WP of the customer hydraulic system.

Yes, ULTIMATE 1SN complies with DIN EN 853 1SN, TS 6387 EN 853 1SN, SAE 100 R1 AT / R1 ATS, ISO 1436:2009, ISO 6805, EN 13463-1 (ATEX), EN 1804-3 (mining) and ISO 1307. This allows direct replacement of hoses from other manufacturers meeting these standards.

The ratio of burst pressure (BP) to working pressure (WP) is 4:1 in all sizes (e.g. DN10: 720 bar BP / 180 bar WP = 4:1). This is the standard safety factor for the EN 853 1SN standard, providing a margin for pressure pulses in dynamic systems.

Yes - ULTIMATE 1SN meets EN 13463-1 (ATEX, non-electrical equipment in explosive atmospheres) and EN 1804-3 (underground mining). It also holds PG (Russian Gosgortechnadzor) and ABS (American Bureau of Shipping) certificates. Full documentation of approvals is available on request.

Standard crimped fittings BSP, JIC 37°, ORFS, METRIC and NPT in all sizes DN5-DN76. The manufacturer offers a full hose assembly service - complete solutions with crimp fittings matched to the specific customer application.
