Description

When you’re dealing with hydraulic leaks on your tractor or implement, it’s usually not the big dramatic failure that gets you—it’s that annoying little seep that gets worse and worse until you’re losing hydraulic fluid all over the barn floor. These Buna-N o-rings are the workhorses of hydraulic sealing, designed to stop those leaks before they turn into expensive downtime.

What You’re Getting

Pack of 10 high-quality Buna-N rubber o-rings for multiple repairs or keeping spares on hand
70 durometer rating provides the right balance of flexibility and strength for farm equipment pressures
Chemical resistance to hydraulic fluids, oils, and the dirt and grime that comes with farm work
Standard 1/8 inch cross-section fits common hydraulic fittings and cylinder applications
Temperature range that handles everything from winter startups to summer heat

Built for Real Farm Work

These o-rings are sized for hydraulic cylinders, lift arms, and implement connections found on tractors, loaders, and attachments. The 2 inch inside diameter makes them perfect for mid-size hydraulic components—not too small for serious equipment, not oversized for compact applications. You’ll find this size in everything from cylinder rod seals to hydraulic motor housings.

Made to Last

Buna-N rubber is the go-to material for hydraulic seals because it handles petroleum-based fluids without swelling or breaking down. The 70 durometer rating means these rings are firm enough to maintain their seal under pressure but flexible enough to handle the constant movement and vibration of working equipment.

Good to Know

Always keep your hydraulic system clean when replacing o-rings—even tiny particles of dirt will cut new seals. A light coating of hydraulic fluid on the o-ring helps with installation and prevents nicking. Having a 10-pack means you’ll have spares when that seal decides to fail at the worst possible moment.
