How Often To Replace Hydraulic Hoses?

September 08, 2023

Hydraulic hoses might not be something you think about every day, but they're like the veins of many machines and systems that power our world. They are significant in transmitting power within hydraulic systems, especially in construction equipment, manufacturing machinery, and your car's brake system.

Yet, despite their importance, they are often overlooked until something goes wrong.

This blog post explores when and why you should replace hydraulic hoses to avoid costly downtime, environmental hazards, and safety risks.

 

Hydraulic Hoses Lifespan

Sometimes, hydraulic hoses don't develop any apparent issues—they simply age over time. Whether they're actively in use or sitting on a shelf as spares, both scenarios can lead to hose failure due to aging alone. Generally, a hydraulic hose's lifespan falls in the range of about five to six years, though some can endure for as long as ten years.

The most telling sign that your hose has reached the end of its lifespan is when it becomes brittle and starts cracking. This aging process can happen gradually, and it's a clear indicator that it's time to consider replacing the hose.

 

Other Signs that Indicate End of Hydraulic a Hose Lifespan

Hydraulic hoses operate under demanding conditions, subjected to high pressures, extreme temperatures, and constant movement. Over time, wear and tear can occur, compromising the efficiency and safety of the entire hydraulic system. Common signs of hose wear and damage include:

#1 Leakage

Hydraulic fluid leakage is a telltale sign of a compromised hydraulic hose. Even small leaks can lead to significant problems if not addressed.


#2 Cracks

Visual inspections may reveal cracks in the hose's outer cover. These cracks often occur due to factors such as age, exposure to harsh environmental conditions, or excessive bending during operation.


#3 Bulges

Bulging areas on the surface of a hydraulic hose suggest a potential weakening of the inner layers. These bulges can result from various factors, such as pressure spikes or prolonged exposure to extreme temperatures. When the inner layers weaken, it can lead to a catastrophic failure of the hose, which can be dangerous and costly.


#4 Abrasions

Hoses in contact with abrasive materials or surfaces can develop abrasions on their outer layer. These abrasions wear down the protective covering of the hose, reducing its overall lifespan.


#5 Kinks

Improper hose installation or routing can lead to kinks in hydraulic hoses. Kinks obstruct the smooth flow of hydraulic fluid, causing inefficiencies and potentially damaging the hose over time. Furthermore, they can create pressure points within the hose, increasing the risk of fatigue and eventual failure.


#6 Corrosion or Cracked Fittings

In addition to issues directly affecting the hose itself, corrosion on fittings or cracked fittings can signal potential problems. Corrosion can weaken the connection and compromise its ability to seal properly, leading to fluid leaks and reduced efficiency.

 

General Guidelines for Replacing Hydraulic Hoses

Now that we've explored the factors influencing a hose’s lifespan, let's discuss some general guidelines for replacing hydraulic hoses. While specific replacement intervals can vary based on factors like the type of hydraulic system and its usage, it's essential to have a proactive approach. Waiting until a hose fails can result in costly downtime and repairs.

A common rule of thumb is to replace hydraulic hoses every 2 to 5 years, even if they appear to be in good condition.

Additionally, you can replace them after reaching a certain number of hours of operation, as the hydraulic hoses manufacturer recommends.

Why is proactive replacement a good strategy? Because hoses may deteriorate from the inside, weakening internal layers over time. And since internal wear is not always visible, preventive replacement becomes the safest choice.


Conclusion

In the grand scheme of machinery, hydraulic hoses may not grab the spotlight, but they're the quiet heroes that ensure your systems run smoothly and safely. Knowing when to replace them can prevent unexpected disruptions and potential hazards. Watch for signs like leakage, bulging, cracking, and even check fittings for corrosion or cracks, as these can jeopardize your hydraulic system's integrity.

Hydraulic Hose Replacement FAQs

How often should I replace hydraulic hoses?

Hydraulic hoses typically have a lifespan of about 5 to 6 years, but this can vary depending on factors like usage, operating conditions, and maintenance. However, we recommend you inspect your hoses regularly and replace them if you notice signs of wear, damage, or aging, even before reaching their maximum lifespan.


What are the signs that my hydraulic hoses need replacement?

Signs of hydraulic hose wear and damage include leakage, cracks in the hose's outer cover, bulges on the surface, abrasions, kinks, and corrosion or cracked fittings. If you observe any of these issues during the inspection, it's a clear indicator that it's time to consider replacing the hose.


Can I extend the lifespan of my hydraulic hoses through maintenance?

Yes, regular maintenance can help prolong the life of hydraulic hoses. This includes visual inspections, proper hose routing, securing hoses, using protective covers in high-wear areas, and following hydraulic hose manufacturer recommendations for maintenance practices. Proactive maintenance can prevent premature hose failure.


Is it necessary to replace hydraulic hoses proactively, even if they seem fine?

Yes, we recommend proactive hose replacement as a preventive measure. Hoses can deteriorate from the inside without visible external signs. Waiting for them to fail can lead to costly downtime, system damage, and safety risks. Replacing hoses within their recommended intervals or when they reach a certain age is a proactive approach.


Are there industry-specific guidelines for hydraulic hose replacement?

Yes. Some industries have specific regulations and standards related to hydraulic hose replacement intervals. For example, the aviation sector has stringent regulations regarding hydraulic hose replacement based on flight hours or calendar time, whichever comes first.
