Description
When hydraulic fluid starts showing up where it shouldn’t be, you’re probably looking at a worn o-ring somewhere in the system. These little rubber rings might be small, but they’re doing big work—keeping hydraulic pressure where it belongs and preventing costly fluid loss. A failed o-ring can turn a simple job into a messy headache, so having the right replacement on hand makes all the difference.
What You’re Getting
- Made from 70 durometer Buna-N rubber that handles hydraulic fluid and temperature changes like a champ
- Black color resists UV degradation better than clear or colored rings
- Precision molded for consistent sealing—no more guessing if it’ll hold pressure
- Chemical resistance that won’t break down from contact with hydraulic oil, diesel fuel, or cleaning solvents
- Temperature range that handles everything from cold morning startups to hot summer field work
Built for Real Farm Work
This o-ring works in hydraulic systems, fuel lines, and other sealing applications across all types of farm equipment. Whether you’re fixing a loader valve, repairing a hydraulic cylinder, or rebuilding a fuel injection pump, Buna-N rubber is the go-to material because it holds up to the fluids and pressures found on working tractors and implements.
Made to Last
Buna-N rubber is the standard for agricultural hydraulics because it stays flexible in cold weather but won’t swell up or deteriorate when exposed to petroleum-based fluids. This material is specifically chosen for farm equipment because it handles the temperature swings and chemical exposure that comes with real farm use.
Good to Know
Always clean the groove thoroughly before installing a new o-ring—dirt or old rubber bits will cause leaks even with a perfect new seal. A light coating of hydraulic fluid helps the ring seat properly during installation. If you’re doing hydraulic work, it’s smart to order a few different sizes since you’ll likely find more than one that needs replacing once you start digging into the system.
