Description
Nothing stops a productive day faster than a hydraulic leak dripping fluid all over your work area. Whether you’re dealing with a loader that’s lost its lift or an implement that won’t angle right, a worn o-ring is often the culprit. This 3-3/8 inch ID Buna-N o-ring gets your equipment sealed back up and running like it should.
What You’re Getting
- Heavy-duty Buna-N rubber that handles the pressure and temperature swings of hydraulic systems
- 70 durometer hardness that stays flexible but won’t tear or deform under pressure
- Precise 3-3/8 inch inside diameter and 3-3/4 inch outside diameter for an exact fit
- Ten rings per package so you’ll have spares when the next repair comes up
Built for Real Farm Work
These o-rings handle the tough conditions you’ll find in hydraulic cylinders, valve blocks, and pump housings across all kinds of farm equipment. Whether you’re fixing a leaky hydraulic line on your loader tractor or rebuilding cylinders on your hay equipment, this size fits a wide range of applications where a reliable seal makes all the difference.
Made to Last
Buna-N rubber is the go-to material for hydraulic systems because it resists hydraulic oil, diesel fuel, and the temperature extremes your equipment faces. The 70 durometer rating means these rings stay soft enough to seal properly while being firm enough to handle high pressures without extruding or tearing.
Good to Know
When replacing o-rings, clean the groove thoroughly and check for any scratches or burrs that could damage the new seal. A light coat of hydraulic fluid on the ring makes installation easier and helps prevent tearing during assembly. Keep the extras in your toolbox—you’ll be glad to have them when you need a quick fix.
