Description
If you’ve noticed hydraulic fluid seeping around connections or drops under your tractor, chances are it’s a worn O-ring that’s the culprit. These little rubber rings might look simple, but they’re working hard every day to keep your hydraulic system sealed tight under thousands of pounds of pressure. When one starts to leak, it’s not just messy—it can lead to air in the system, poor implement performance, and expensive hydraulic fluid loss.
What You’re Getting
- Precision-sized to maintain tight seals in New Holland and Case IH hydraulic systems
- High-quality rubber compound that resists hydraulic fluids, heat, and pressure cycling
- Factory specifications ensure proper fit without over-compression or gaps
- Direct replacement for original equipment—no guesswork on sizing
Built for Real Farm Work
This O-ring fits a wide range of New Holland tractors from utility T4 models up through the bigger T6 and T7 series, plus Case IH Farmall, Puma, and Vestrum tractors. Whether you’re running a loader, operating hydraulic remotes for implements, or just need reliable power steering, your hydraulic system depends on proper sealing to maintain pressure and keep contaminants out.
Made to Last
Farm hydraulics take a beating with constant pressure changes, temperature swings, and exposure to different fluids. This O-ring is built with the right rubber compound to handle modern hydraulic fluids without swelling, cracking, or hardening. It maintains flexibility through temperature extremes and keeps its sealing properties season after season.
Good to Know
When replacing hydraulic O-rings, clean the groove thoroughly and check for any sharp edges that could cut the new ring. A light coating of hydraulic fluid on the O-ring helps installation and prevents damage. If you’re seeing multiple leaks, it’s often worth replacing several O-rings while you have things apart—they tend to age together.
