Description
When your hydraulic fittings start weeping fluid or that valve isn’t sealing quite right, a fresh O-ring can often solve the problem for just a few dollars. These little rubber rings might seem simple, but they’re what keep your hydraulic systems running tight—and fluid where it belongs instead of on the ground under your tractor.
What You’re Getting
- Buna-N rubber construction that resists hydraulic oil, diesel, and most farm chemicals
- 70 durometer hardness strikes the right balance between flexibility and durability
- Precise 9/16 inch inside diameter and 11/16 inch outside diameter for proper sealing
- Thin 1/16 inch cross-section fits in standard O-ring grooves
- Ten O-rings per pack so you’ve got spares on hand for the next repair
Built for Real Farm Work
These O-rings work in plumbing, hydraulics, heavy equipment, automotive, and irrigation applications where you need a reliable seal. Whether you’re rebuilding a hydraulic cylinder, fixing a leaky fitting, or replacing worn seals in implements, this size handles many common repair jobs around the farm.
Made to Last
Made of 70 Durometer Buna-N Rubber, these O-rings handle temperature swings from winter shop work to summer field operations. The Buna-N material resists swelling in hydraulic oil and won’t crack from repeated pressure cycles like cheaper rubber compounds might.
Good to Know
Always clean the O-ring groove thoroughly before installing a new seal—old rubber bits or debris cause leaks. A light coating of hydraulic fluid helps the O-ring slip into place without nicking or twisting. Keep extras in your toolbox since O-rings have a way of disappearing when you drop them.
