Hydraulic seals are soft, non-metallic rings that are used to contain and prevent the leakage of fluid between components. While these seals are created to be highly durable, when used improperly, it can result in serious issues with your equipment. R. A. Heller Co.,  is the leading machine shop in Cincinnati, OH, offering a wide range of services, from piston rod repairs to hard chrome plating. They are here to discuss a few of the causes of hydraulic seal failure.  

5 Reasons for Hydraulic Seal Failures

1. Hardening

Exposure to high temperatures can significantly decrease the life span of a hydraulic seal. Heat causes them to melt and re-harden, leading to cracks and erosion. You can prevent this by purchasing rings that are made from heat-resistant material.

2. Fractures

Fractures can occur when there is a burn, break, or crack on the dynamic side of the hydraulic seal. These are usually the result of high-pressure shocks or the usage of low-quality materials during the manufacturing process.

3. Improper Installations

Improper installation may cause a wide variety of problems that shorten the life span of a hydraulic seal, such as unsafe handling and incorrect sizing. This issue can be prevented by ensuring the hydraulic seal is built according to the size before the sealing.

4. Contamination

Contamination occurs when external flotsam and jetsam is introduced into the hydraulic rod. The hydraulic piston is then covered with dirt and mud, and it reaches the seal. A dirty seal is unable to prevent contaminants from entering the piston area, which is why it’s important to ensure it is always clean and free from dust, especially upon installation.

5. Chemical Erosion

Chemical erosion occurs when the seal is exposed to various types of materials that cause degradation. This can easily be prevented by ensuring the seal material is a good match for the chemicals that will be introduced during the application. 

Keeping the above causes in mind can help to reduce the damage inflicted upon your hydraulic seals. When it’s time to purchase industrial parts or schedule piston rod repairs, turn to the team at R.
