What is the typical lifespan of a hydraulic rubber hose?

The lifespan of a hydraulic rubber hose is affected by various factors, including material quality, operating conditions, working pressure, temperature, media type, and maintenance.

Here are some general guidelines:
Material Quality: High-quality rubber and reinforcing layers can significantly improve hose lifespan.
Working Pressure: Higher working pressures may shorten the hose's lifespan.
Temperature: Hoses exhibit varying durability at different temperatures. High temperatures accelerate the aging process, while low temperatures may cause the rubber to harden and become brittle.
*Media Type: Different hydraulic oils or media have varying degrees of corrosiveness to rubber, also affecting hose lifespan.

Generally, the lifespan of a hydraulic rubber hose is as follows:
Indoor Environment: Under normal operating conditions, the lifespan of a hydraulic rubber hose is approximately 5 to 10 years.
Outdoor Environment: Due to factors such as ultraviolet radiation, ozone, and temperature fluctuations, the lifespan of hoses used outdoors may be shorter, possibly around 3 to 5 years.

To extend the lifespan of hydraulic rubber hoses, the following maintenance recommendations are provided:
Regularly inspect the hose to ensure there are no cracks, wear, or other damage.

Avoid excessive bending or twisting of the hose, as this may cause the inner rubber layer to crack.

Keep the hose away from sharp objects and high-temperature areas.

Use appropriate hoses and fittings, ensuring they are compatible with the hydraulic system.

Please note that these are only approximate estimates; actual lifespan may vary depending on specific usage conditions.
