We’ve all been there—hydraulic fluid dripping under your tractor, loader cylinders that won’t hold pressure, or fittings that seep just enough to make a mess in the shop. Often it’s not the big, expensive components that fail, but something as simple as a worn O-ring letting you down. This 10-pack of 2-1/4 inch inside diameter Buna-N rubber O-rings gives you the reliable seals you need to stop those leaks and keep your hydraulic systems running tight.
What You’re Getting
- Quality 70 durometer Buna-N rubber that handles hydraulic fluid and temperature swings
- Precise 2-1/4 inch inside diameter fits common hydraulic cylinders and fittings
- 3/32 inch cross-section provides the right seal without over-compression
- 10-pack quantity means you’ll have spares when you need them most
- Fits a wide range of hydraulic applications from loader cylinders to valve assemblies
Built for Real Farm Work
These O-rings are sized for the hydraulic components you see every day on tractors and implements. Whether it’s sealing a cylinder on your three-point hitch, fixing a leaky fitting on your loader, or rebuilding a hydraulic valve, this size shows up in everything from utility tractors to large row-crop machines. The 2-1/4 inch bore size is common in mid-size hydraulic cylinders and various valve bodies.
Made to Last
Buna-N rubber stands up to hydraulic oil, temperature changes, and the pressure cycles that come with farm work. The 70 durometer rating gives you the right balance of flexibility for sealing and firmness to resist extrusion under pressure. These aren’t the cheap substitutes that get hard and crack after a season—they’re built for the demanding conditions of agricultural hydraulics.
Good to Know
Keep the O-ring groove clean when installing—old rubber bits or dirt cause new seals to fail quickly. A light coating of hydraulic fluid on the O-ring makes installation easier and prevents tearing. Don’t stretch the ring more than necessary during installation, and always replace the O-ring if you nick it with a tool. Having a 10-pack on hand means you’re ready for the next seal job without a trip to town.
