R 7 - HYDRAULIC PLASTIC DOUBLE BRAID HOSE
| R 7 (SAE J517, EN 855, ISO 3949)
|
Double braided plastic hose, conforms to SAE J517, EN 855, ISO 3949, designed for systems using the following fluids:
Mineral-based oils, mineral-based oils with up to 40% aromatics added, rapeseed oils, bio-oils, polyglycol-based oils, water and water-oil emulsions, water-glycol emulsions, air, gas.
|
| STRUCTURE OF THE SLEEVE: |
| Inner layer: |
polyester or polyamide |
| Gain: |
two high tenacity polyester braids |
| Outer layer: |
extremely wear-resistant polyurethane, oil, ozone, grease and weather resistant |
| Working temperature: |
- 40° Ñ to + 100° Ñ (use with air, water and water emulsions + 65° Ñ) |
| The advantage of this sleeve is wear resistance without stretching along the length and low weight. |

Note: It must be remembered that due to prolonged use of the hose at the operating limits (maximum working pressure, maximum temperature, minimum bending radius), the service life of the hose is reduced!
