Description
When you’re dealing with hydraulic leaks or equipment downtime, the last thing you want is to be searching for the right o-ring. This set of 10 high-quality Buna-N o-rings gives you exactly what you need to get your equipment sealed up tight and back to work. Whether it’s a stubborn hydraulic fitting or a critical seal in your tractor’s system, these o-rings deliver the reliable seal you’re counting on.
What You’re Getting
- Ten precision-sized o-rings that fit exactly where they’re supposed to—no guesswork
- 70 durometer Buna-N rubber that flexes with temperature changes but keeps its sealing power
- Versatile design works in plumbing, hydraulics, heavy equipment, automotive, and irrigation systems
- 1/8-inch cross-section provides excellent sealing force without taking up too much groove space
- Smart 10-pack quantity means you’ve got spares when you need them most
Built for Real Farm Work
These o-rings are sized for larger hydraulic fittings and equipment connections that see serious use. The 3-7/8-inch inside diameter makes them perfect for bigger cylinders, pumps, and hydraulic components on tractors, combines, and other heavy equipment. Whether you’re fixing a leaky loader valve or resealing a hydraulic motor, these rings handle the pressure and abuse that comes with farm work.
Made to Last
The 70 durometer Buna-N rubber construction means these o-rings stay flexible in cold weather but won’t get soft and fail when things heat up. They resist oil, fuel, and hydraulic fluid—the stuff that destroys cheap seals. This is the same quality material used in OEM applications, so you know it’ll hold up to whatever your equipment dishes out.
Installation Notes
Measure carefully to ensure both diameter and cross-section match exactly, clean sealing surfaces thoroughly, and lubricate with compatible fluid before installation to prevent rolling or tearing. Having ten in the pack means you can fix what’s broken today and still have spares for the next time something needs attention.
