We know how helpful a hydraulic seal could be, especially for transforming fluid on a hydraulic system. The problem is it could work in uncertain ways. Well, failure is a common thing when we are talking about heavy industries. Even hydraulic seal plays a crucial role in a hydraulic system, a faulty seal design can be complicated.

In this article, we are going to cover seven common causes of hydraulic seal failure. So, it will be helpful for you to repair the seal failure by your self or be knowledgeable when asking for help.

  1. Wear

Due to insufficient lubrication and excessive lateral load, wear could be the cause of hydraulic seal failure. You can find excessive damage on the hydraulic seal because of wear. This could be the cause of other problems. To avoid this problem, you need to maintain regular lubrication for better performance. 

  • Scarring

When the installation is improper, it could cause dents and cuts to the sealing surface. On the other hand, scarring can be identified because of the presence of foreign material on the sealing surface. To prevent scarring, you have to check the hydraulic seals before installation.

  • Hardening

If hydraulic seals are exposed to high fluid temperature or high heat generation, the seals could harden. So, you will see cracks on those seals and it can permanently damage the system. Well, you can easily prevent this issue by reducing the temperature of the hydraulic seal failure.

  • Fracture

Fracture is also a common reason for hydraulic seal failure. Basically, it happens when the system is broken off or the seals are burned. On the other hand, a fracture could occur when there’s excessive backpressure. This is why you need to set the pressure limit. 

  • Improper Installation

As we have mentioned before, improper installment causes a hydraulic seal failure. Because of the improper installment, those seals could create wear, scarring, and fracture. In fact, you will find major damage after some time. Make sure you are hiring an expert team for proper installation.

  • Chemical Erosion

Hydraulic seals could get affected when you are transforming foreign materials throughout the system. Choosing foreign materials could be the cause of hydrolysis, and oil additives. The system will lose the lip seals by chemical erosion. So, make sure you are choosing hydraulic system-compatible materials.

  • Contamination

Some industries don’t even clean the hydraulic system regularly. As various dirt particles like mud and powder get attached to the piston, it could damage the seals. The dirtier these seals become, the more they are losing the ability to transform fluids. To prevent this issue, you need to do regular maintenance.


As a hydraulic seal is a crucial part of a hydraulic system, you need to repair the seal failure as soon as possible. Make sure you are hiring an expert team for the maintenance. However, you need to figure out the actual cause of seal failure first.
