When you’re elbow-deep in a hydraulic repair or doing routine maintenance, the last thing you want is to be held up by a missing O-ring. These 2-3/4″ inside diameter Buna-N O-rings are the workhorse seals you need for keeping hydraulic cylinders, fuel systems, and equipment connections tight. Whether it’s a leaky loader cylinder or a fuel filter housing that’s weeping diesel, having the right size O-ring on hand keeps your repair moving.
What You’re Getting
- 70 durometer Buna-N rubber that handles the heat and pressure of hydraulic systems without breaking down
- 1/8″ cross-section width provides reliable sealing in standard agricultural equipment grooves
- 10-pack quantity means you’ll have spares for future repairs and maintenance
- Chemical resistance to hydraulic fluids, diesel fuel, and most agricultural chemicals you’ll encounter
- Precise 2-3/4″ inside diameter fits common cylinder bores and equipment housings
Built for Real Farm Work
This O-ring size shows up in hydraulic cylinders on front-end loaders, three-point hitch systems, and implement connections across many tractor brands. You’ll also find this dimension in fuel filter housings, hydraulic valve bodies, and various equipment fittings. It’s the kind of seal that keeps hydraulic fluid where it belongs and prevents the air leaks that cause spongy operation.
Made to Last
Buna-N rubber stands up to the temperature swings and chemical exposure that destroy cheaper seals. The 70 durometer rating gives you the right balance of flexibility for sealing and firmness for durability. These seals maintain their shape and sealing properties through countless pressure cycles and temperature changes.
Good to Know
Keep O-ring grooves clean and lightly lubricated during installation to prevent nicking the seal. A light coating of the system fluid helps the O-ring slide into place without twisting or pinching. Store unused O-rings in a cool, dry place away from direct sunlight to keep the rubber in top condition for years.
