Buna-N Rubber O-Ring 3/16 Inch Wide – Universal Hydraulic and Equipment Applications

Description

When your hydraulic system starts weeping fluid or your loader begins feeling sluggish, it’s often a simple o-ring that’s causing the trouble. These little rubber seals work overtime in your tractor’s hydraulic systems, keeping pressure where it belongs and contaminants out. For use in plumbing, hydraulics, heavy equipment, automotive, irrigation and more. This handy 10-pack means you’ll have spares on hand when you need them most.

What You’re Getting

• Made of 70 Durometer Buna-N Rubber that handles the temperature swings and chemical exposure common in farm hydraulics
• Precision 3/16-inch width with 1-5/8-inch inside diameter gives you the exact fit for proper sealing
• Ten o-rings per package means you can fix the problem and have spares for future repairs
• Universal size that fits a wide range of hydraulic fittings and connections across different equipment brands

Built for Real Farm Work

These o-rings are the workhorses of hydraulic systems – from your tractor’s three-point hitch cylinders to loader valve stacks and remote hydraulic outlets. The cylinder construction stands up to the bumps and vibration that come with field operations, while the seals keep working season after season. You’ll find this size in everything from compact utility tractors to full-size row crop machines, making them a smart addition to your parts inventory.

Made to Last

Buna-N rubber is the gold standard for agricultural hydraulic seals because it resists the petroleum-based fluids, temperature extremes, and constant pressure cycling that destroy cheaper materials. The 70 durometer rating gives you the perfect balance of flexibility for sealing and firmness for durability under pressure.

Good to Know

Always replace o-rings in sets when doing hydraulic work – if one failed, the others have endured the same conditions and won’t be far behind. Keep the seal kit handy for future maintenance—hydraulic cylinders work hard in dirty farm conditions and occasional seal replacement keeps them working smooth. A dab of hydraulic fluid on the o-ring makes installation easier and prevents damage during assembly.
