When your hydraulic couplers start leaking or getting hard to connect, those little O-rings inside the coupling liners are usually the culprit. Quick release coupling insert internal O-rings take a beating from constant connect-disconnect cycles, hydraulic pressure, and contamination. This complete kit gives you the seals needed to rebuild several coupling inserts and get your hydraulic connections working like new again. What You're Getting Complete O-ring set for multiple coupling liner rebuilds - covers several units at once Works with the liner inserts in your existing quick release couplings - no need to replace entire assemblies Precision-molded rings that maintain proper sealing under hydraulic pressure Designed to handle the repeated flexing and pressure cycling of daily farm use Built for Real Farm Work This kit covers an impressive range of John Deere tractors across multiple generations, from the compact 30 Series through the powerful 7010 Series machines. Whether you're running a 1350 on hay equipment, using a 4050 for heavy tillage, or operating a 6910 with a loader, these are the same seals that keep your hydraulic connections tight and leak-free. Made to Last Farm hydraulics see constant use and abuse - dust, dirt, pressure spikes, and temperature swings. These O-rings are built from hydraulic-grade compounds that resist hydraulic fluid, maintain flexibility in cold weather, and stand up to the pressure cycles that come with connecting implements all day long. Good to Know When rebuilding coupling liners, cleanliness is critical - any dirt that gets inside will damage your new seals. Clean everything thoroughly with hydraulic fluid before assembly. If one coupling is showing wear, the others aren't far behind - this kit lets you service several at once during winter maintenance instead of dealing with failures during busy seasons.
