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.
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.
