- 01Its main advantages are:
- 02High pressure resistance
- 03Double steel reinforcement: two layers of high-strength braided steel withstand working pressures from 80 to 415 bar, depending on diameter.
- 04High safety factor: a 4:1 safety margin means the burst pressure is four times higher than the maximum working pressure.
- 05Impulse resistance: withstands sudden pressure spikes and continuous dynamic loads.
- 06Construction flexibility
- 07Flexible braided structure: compared with four-layer spiral hoses, 2SN hose is much more flexible and has a smaller bend radius.
- 08Light weight: provides the required strength while remaining easy to install and route through the system.
- 09Wide compatibility
- 10Oil-resistant inner tube: the synthetic-rubber inner tube is compatible with hydraulic oils, lubricants, and water-oil emulsions.
- 11Temperature range: operates stably from -40°C to +100°C, with short-term peaks up to +120°C.
- 12Outer protective layer
- 13Environmental resistance: the durable synthetic-rubber outer cover protects the steel reinforcement against ozone, sunlight, abrasion, and mechanical damage.
