STANDARD: SAE 100 R19
TUBE:  oil resistant synthetic rubber  
REINFORCEMENT: one or two layers of braided high-strength super-flexible steel wire
COVER:oil, wear, & extreme weather resistant synthetic rubber
TEMPERATURE RANGE:   -40ºC /+100ºC ; -40 °F/+212°F   LT-55 & HT150ºC customizable
APPLICATION: suitable for machine tools, agricultural applications, construction machinery, oil drilling, mining machinery, steel, chemical industry, energy, rail transit, food processing and shipbuilding


Construction:

The hose is composed of an inner tube of oil resistant synthetic rubber, 4 layers of spiral wire reinforcement, and an oil and weather resistant synthetic rubber cover. The internal rubber bears the pressure of delivery medium in order to protect the steel wire from corrupting while the enforced wire-wood layer increases the firmness of the hose.

Recommended For: extremely high pressure&high impulse hydraulic systems. 4SH series are the most flexible hoses among standard EN856 series with outstanding impulse performance.They are used for biodegradable hydraulic fluid, such as: synthetic esters, polyethylene glycol, vegetable oils and petroleum-based fluids.

Advantages:
1.Selection of synthetic rubber hose with special made, with excellent oil resistance, heat resistance, anti-aging properties.
2. Hose for the high-pressure and superior pulse properties.
3. Hose combination of close, use soft, small deformation under pressure.
4. Hose has an excellent circumnutate resistance and fatigue resistance.
