Description

When your hydraulic system starts leaking or you notice that three-point hitch dropping overnight, a worn piston O-ring is often the culprit. This small but critical seal keeps hydraulic pressure where it belongs – inside your cylinders and pistons, not on the shop floor. It’s one of those parts that you don’t think about until it fails, but when it does, you’ll know it right away.

What You’re Getting

Perfect fit for hydraulic pistons in multiple Massey Ferguson series
Quality rubber compound that stands up to hydraulic fluid and temperature swings
Proper sealing to prevent internal bypass and maintain system pressure
Direct replacement – no modifications needed

Built for Real Farm Work

These compatible tractors represent some of the most popular and reliable agricultural machines ever produced, used as workhorses across diverse farming operations including row crop cultivation, hay production, livestock farming, and general farm maintenance. Whether you’re running a loader on your 175, operating a three-point hitch on your 275, or using hydraulic remotes on your 590, this O-ring helps maintain the pressure that makes it all work smoothly.

Made to Last

Farm hydraulics take a beating with constant pressure cycles, temperature changes, and dirty conditions. This O-ring is built with the right rubber compound to handle hydraulic fluid without swelling or cracking over time. When one O-ring fails, others aren’t far behind since they’ve all aged together in the same hydraulic fluid, dealt with the same heat cycles, and endured the same years of pressure.

Installation Notes

Clean the piston groove thoroughly before installing the new O-ring – old rubber fragments left behind cause leaks. Use a bit of hydraulic fluid on new O-rings during installation; never force them. If you’re doing one piston, it’s worth checking the others while you’re at it. They often wear out together, and it saves you from tearing back into the same job next season.
