Description
When you’re dealing with hydraulic leaks or sealing problems on your tractor or equipment, having the right O-ring can save you from bigger headaches down the road. This black Buna-N rubber O-ring is designed to handle the pressures and temperatures you’ll find in agricultural hydraulic systems, keeping fluid where it belongs so your equipment keeps working when you need it most.
What You’re Getting
- Black Buna-N rubber construction that resists oil, fuel, and hydraulic fluid breakdown
- Designed to handle temperature swings from cold mornings to hot summer field work
- Maintains flexibility and sealing properties under pressure and vibration
- Standard sizing that fits a wide range of agricultural equipment applications
Built for Real Farm Work
This O-ring works well in plumbing, hydraulics, heavy equipment, automotive, and irrigation applications. From hydraulic cylinders and valve blocks to transmission seals and hydraulic pumps, it’s the kind of basic seal that keeps tractors, combines, and implements functioning properly across all types of farm operations.
Made to Last
Buna-N rubber stands up to the harsh conditions found on working farms—diesel fuel contact, hydraulic oil exposure, temperature extremes, and constant vibration. The 70 durometer rating gives you the right balance of flexibility for sealing and firmness to resist extrusion under pressure.
Good to Know
Always clean the groove thoroughly before installing a new O-ring—any dirt or old seal material will cause premature failure. A light coating of hydraulic fluid or compatible grease helps with installation and prevents the seal from twisting or cutting during assembly.
