When should you replace the rubber oil hose
Environment and storage
Suitable temperature
Rubber oil hose is sensitive to temperature and are generally suitable for use in an environment of -20℃ to 80℃. If the temperature is too high, the rubber will age and soften faster. This will cause the strength of the oil hose to decrease and leak easily. If the temperature is too low, the rubber will become hard and brittle and lose its elasticity. Therefore, it is easy to break when bent or impacted.
Avoid exposure and moisture
Rubber oil hoses should be stored in a cool, dry and well-ventilated place. Avoid direct sunlight and humid environments. Ultraviolet rays in sunlight can cause photoaging of rubber and reduce its performance. Humid environments may cause mildew on the surface of rubber and affect its service life.
Keep away from chemicals
Rubber oil hoses should not come into contact with chemicals such as acids, alkalis, and organic solvents. Because these substances will react chemically with rubber. Then the rubber will swell, dissolve or embrittle, damaging the oil hose. For example, although organic solvents such as gasoline and diesel can be transmitted through rubber oil hoses, it is necessary to ensure that there is no leakage. And the oil hose cannot be immersed in it for a long time.
Installation and operation
Correct installation
Make sure the oil hose is firmly connected during installation. At the same time, avoid twisting, bending or excessive stretching. If installed improperly, stress concentration will occur inside the oil pipe. While this is prone to rupture or leakage during use. For example, when installing the engine rubber oil pipe, it must be installed in accordance with the specified direction and angle, and fastened with clamps and other fixings.
Prevent friction
During use, prevent the rubber oil pipe from rubbing or colliding with other objects. Friction will wear the outer surface of the rubber oil pipe, thin the rubber layer, and reduce the strength and sealing of the oil pipe. The oil pipe can be prevented from contacting with sharp objects or moving parts by adding a hose sheath.
