At Union Hydraulics, we know how frustrating it can be when a hydraulic motor starts leaking, losing efficiency, or simply not performing as it should. In many cases, the issue isn’t the motor itself—it’s worn or failing seals. That’s where our Parker® Motor Seal Kits come in.
These kits are designed to restore performance, extend the life of your motor, and get your equipment back up and running without the cost of a full replacement.
What Are Parker® Motor Seal Kits?
Parker® Motor Seal Kits include the essential sealing components needed to rebuild and reseal hydraulic motors. Over time, seals break down due to pressure, heat, contamination, and normal wear. When that happens, you’ll typically notice leaks, reduced torque, or inconsistent operation.
Instead of replacing the entire motor, a properly matched seal kit allows you to rebuild it—bringing it back to optimal working condition.
At Union Hydraulics, we supply high-quality seal kits designed to meet or exceed OEM specifications, so you can trust the fit, performance, and durability.
When Should You Replace Motor Seals?
If you're on the fence about whether you need a seal kit, here are a few common signs we see from customers:
- Hydraulic fluid is leaking around the motor housing
- Loss of pressure or reduced motor efficiency
- Sluggish or inconsistent motor performance
- Visible wear or damage during routine maintenance
- Equipment downtime caused by seal failure
In real-world applications—whether you're running skid steers, agricultural equipment, or industrial machinery—these issues tend to show up at the worst possible time. Having the right seal kit on hand can save you both time and money.
What’s Typically Included in a Seal Kit?
While contents can vary depending on the motor model, most Parker® Motor Seal Kits include:
- O-rings
- Shaft seals
- Backup rings
- Wear rings
- Gaskets or specialty seals specific to the motor design
Each component plays a critical role in maintaining proper pressure, preventing leaks, and ensuring smooth operation under load.

Tips for a Successful Seal Replacement
If you’re planning to install a seal kit yourself, here are a few practical tips:
- Always clean all components thoroughly before installation
- Inspect shafts and housings for scoring or damage
- Use proper lubrication during installation to prevent seal damage
- Follow the manufacturer's torque and assembly specifications
- Replace all seals in the kit—not just the failed one
Taking a little extra time during installation can make a big difference in long-term performance.
