Hydraulic hose for railways DN10 1SN 180 bar (EN 45545-2)

Specialist hydraulic hose for railways DN10 1SN with a working pressure of 180 bar is a flexible pressure hose with a single steel braid, designed for the rigorous requirements of rail transport and rolling stock. The hose meets the European fire protection standard EN 45545-2, which qualifies it for use in locomotives, passenger carriages, power units, as well as trams and track machinery. The outer cover made of flame-retardant, self-extinguishing synthetic rubber is characterized by very low smoke and toxic gas emissions in the event of a fire. The hose is designed for the leak-free transport of mineral and synthetic oils, hydraulic fluids, water-glycol solutions, water, and compressed air in drive, control, and auxiliary systems.

Application, construction, and advantages of the DN10 1SN railway hose

In rail vehicle installations, flexible pressure connections are subjected to vibrations, temperature changes, and atmospheric influences. The DN10 1SN 180 bar railway hose combines mechanical strength with the fire safety requirements of the railway industry.

EN 45545-2 fire certification: The outer synthetic rubber meets the requirements for flammability and low exhaust toxicity (HL1, HL2, HL3 levels).
Compliance with hydraulic standards: Manufactured according to EN 853 1SN and SAE 100 R1AT standards, allowing use with standard crimp fittings.
Single-braid steel construction: Reinforcement with a single high-tensile steel braid provides flexibility and a small bending radius at a working pressure of 180 bar.
Wide operating temperature range: From -40°C to +100°C (periodically up to +125°C), enabling stable operation in winter conditions and with hot oil.
Environmental resistance: The rubber cover is resistant to abrasion, ozone, UV radiation, petroleum fluids, and atmospheric factors.

What to connect the DN10 1SN railway hose with and how to avoid assembly errors?

Hydraulic hose for railways DN10 1SN (inner diameter 3/8" – approx. 9.5 mm) works with standard power hydraulic fittings:

Hose crimp fittings: Standard metric fittings (DKOL/DKOS, CEL/CES), inch BSP (DKR, AGR), JIC, and ORFS sealed with T20 or T21 DN10 (3/8") crimp sleeves.
Working media: Petroleum-based hydraulic oils, synthetic esters, cooling fluids (glycol), water, and compressed air.

When selecting and installing railway hoses, the required system working pressure must be carefully verified. For DN10 (3/8") diameter, the 1SN version offers a working pressure of 180 bar with a 4:1 safety factor (burst pressure is min. 720 bar). If the system requires higher pressure (e.g., up to 330 bar), the double-braid 2SN version should be used. Correct sleeve crimping on the crimping machine depends on the crimping table provided by the fittings and hose manufacturer.

Frequently Asked Questions (FAQ)

What does the EN 45545-2 standard mean for a hydraulic hose?

The EN 45545-2 standard defines the fire performance requirements for materials used in rail vehicles. A hose meeting this standard has a flame-retardant outer cover that limits the spread of fire and emits a small amount of smoke and toxic gases.

Do standard fittings and sleeves fit the DN10 1SN railway hose?

Yes, the geometric dimensions of the 1SN hose compliant with the EN 45545-2 standard correspond to standard EN 853 norms. Common hydraulic fittings and T20 or T21 DN10 crimp sleeves are used for crimping.
