Hydraulic Cylinder Seal Replacement: When and How to Do It
Hercules Sealing Products
Hercules Sealing Products is the leading distributor of hydraulic and pneumatic seals, seal kits and cylinders.
Hydraulic cylinders are essential components in many industrial and mobile applications, responsible for converting fluid power into mechanical force. However, the seals within these cylinders play a critical role in ensuring efficient operation by preventing fluid leaks. Over time, these seals wear out, leading to performance issues and potential system failure.
In this article, we’ll explore when hydraulic cylinder seals should be replaced and how to do it effectively, with tips from Hercules Sealing Products, your trusted source for hydraulic seal kits and hydraulic parts.
Why Hydraulic Cylinder Seals Need Replacing
Hydraulic cylinder seals are constantly subjected to high pressure, temperature fluctuations, and friction. This wear and tear can lead to diminished performance or even complete failure if not addressed promptly.
Common Signs of Seal Wear and Failure
Knowing the warning signs of seal wear can save you from costly downtime. Some of the most common indicators include:

When to Replace Hydraulic Cylinder Seals
Replacing hydraulic seals at the right time is crucial for preventing more severe damage to your hydraulic system.
Recommended Maintenance Intervals
No single answer exists for how often you should replace hydraulic seals. It depends on the cylinder's environment, workload, and application type. However, you should inspect seals every 1,000 hours of operation or annually, whichever comes first. Keep in mind that exposure to extreme temperatures, contamination, or overpressure can shorten seal life significantly.
Emergency Repairs vs. Scheduled Maintenance
Emergency repairs can be costly and time-consuming. Proactively scheduling seal replacement during regular maintenance intervals helps avoid unexpected breakdowns. Hercules Sealing Products provides different replacement seal kits. These kits help you plan for maintenance and reduce downtime.

Step 1: Disassembly of the Hydraulic Cylinder
Start by safely disconnecting the hydraulic cylinder from the system. Next, disassemble the cylinder according to the manufacturer’s specifications. Carefully remove the piston and gland from the cylinder barrel, and then extract the old seals.
Step 2: Inspecting Components
Once disassembled, thoroughly inspect the piston rod, gland, and cylinder bore for signs of wear, scoring, or corrosion. If any component shows damage, replacing it with new parts from Hercules Sealing Products ensures optimal performance after the seal replacement.

Step 3: Installing the New Seals
Before installing new seals, apply a small amount of hydraulic oil or lubricant to them. Gently slide the new seals into the right grooves on the piston and gland. Make sure they fit well without twisting or stretching.

Step 4: Reassembling the Cylinder
After the new seals are installed, reassemble the hydraulic cylinder in the reverse order of disassembly. Make sure to tighten all fasteners correctly. Test the cylinder by cycling through several strokes. This will help check for leaks or problems.
Tips to Extend the Life of Hydraulic Cylinder Seals
While replacing seals is an inevitable part of hydraulic cylinder maintenance, taking proactive steps can help extend their lifespan.
Proper Lubrication
One of the simplest ways to protect your seals is by keeping them well-lubricated. This reduces friction, minimizing wear and tear.
Regular Maintenance
Regularly inspecting your hydraulic cylinder performance for early signs of wear helps prevent costly breakdowns. Keep the hydraulic fluid clean and free from contaminants to reduce the risk of seal damage.
